Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure	Business Description Amcor plc ("Amcor" or the "Company") is a holding company incorporated under the name Arctic Jersey Limited as a limited company incorporated under the laws of the Bailiwick of Jersey in July, 2018, in order to effect the Company's combination with Bemis Company, Inc. On October 10, 2018, Arctic Jersey Limited was renamed "Amcor plc" and became a public limited company incorporated under the Laws of the Bailiwick of Jersey. The Company develops and produces a broad range of packaging products including flexible packaging, rigid containers, specialty cartons, and closures. On June 11, 2019, the Company completed its acquisition of Bemis Company, Inc ("Bemis").

Significant Accounting Policies

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Significant Accounting Policies Basis of Presentation and Principles of Consolidation: The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All intercompany transactions and balances have been eliminated. The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). Business Combinations: The Company uses the acquisition method of accounting, which requires separate recognition of assets acquired and liabilities assumed from goodwill, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the fair value of any non-controlling interests in the acquiree over the net of the acquisition date fair values of the assets acquired and liabilities assumed. During the measurement period, which may be up to one year from the acquisition date, the Company has the ability to record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded in the consolidated income statement. Discontinued Operations Presentation: The consolidated financial statements and related notes reflect the three plants in Europe acquired as part of the Bemis acquisition as a discontinued operation (see Note 5 , " Discontinued Operations ") as the Company agreed to divest of these plants as a condition of approval from the European Commission. Estimates and Assumptions Required: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. These estimates are based on historical experience and various assumptions believed to be reasonable under the circumstances. Management evaluates these estimates on an ongoing basis and adjusts or revises the estimates as circumstances change. As future events and their impacts cannot be determined with precision, actual results may differ from these estimates. In the opinion of management, the consolidated financial statements reflect all adjustments necessary to fairly present the results of the periods presented. Translation of Foreign Currencies: The reporting currency of the Company is the U.S. dollar. The functional currency of the Company’s subsidiaries is generally the local currency of such entity. Transactions in currencies other than the functional currency of the entity are recorded at the rates of exchange prevailing at the date of the transaction. Monetary assets and liabilities in currencies other than the entity’s functional currency are remeasured at the exchange rate as of the balance sheet date to the entity’s functional currency. Foreign currency transaction gains and losses related to short-term and long-term debt are recorded in other non-operating income (loss), net in the consolidated income statements. The Company recorded such foreign currency transaction net gains (losses) of $1.1 million , $(82.7) million and $40.7 million during the years ended June 30, 2019, 2018 and 2017, respectively. All other foreign currency transaction gains and losses are recorded in other income, net in the consolidated income statements. These foreign currency transaction net gains (losses) amounted to $8.9 million , $1.0 million and $1.0 million during the years ended June 30, 2019, 2018 and 2017, respectively. Upon consolidation, the results of operations of subsidiaries whose functional currency is other than the reporting currency of the Company are translated using average exchange rates in effect during each year. Assets and liabilities of operations with a functional currency other than the U.S. dollar are translated at the exchange rate as of the balance sheet date, while equity balances are translated at historical rates. Translation gains and losses are reported in accumulated other comprehensive income (loss) as a component of shareholders’ equity. Revenue Recognition: The Company generates revenue by providing its customers with flexible and rigid packaging serving a variety of markets including food, consumer products and healthcare end markets. The Company enters into a variety of agreements with customers, including quality agreements, pricing agreements and master supply agreements which outline the terms under which the Company does business with a specific customer. The Company also sells to some customers solely based on purchase orders. The Company has concluded for the vast majority of its revenues, that its contracts with customers are either a purchase order or the combination of a purchase order with a master supply agreement. All revenue recognized in the income statement is considered to be revenue from contracts with customers. The Company typically satisfies the obligation to provide packaging to customers at a point in time upon shipment when control is transferred to customers. Revenue is recognized net of allowances for returns and customer claims and any taxes collected from customers, which are subsequently remitted to governmental authorities. The Company does not have any material contract assets or contract liabilities. The Company disaggregates revenue based on geography. Disaggregation of revenue is presented in Note 20 , " Segments ". Significant Judgments Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. The Company identified potential performance obligations in its customer master supply agreements and determined that none of them are capable of being distinct as the customer can only benefit from the supplied packaging. Therefore, the Company has concluded that it has one performance obligation to supply packaging to customers. The Company may provide variable consideration in several forms which are determined through its agreements with customers. The Company can offer prompt payment discounts, sales rebates or other incentive payments to customers. Sales rebates and other incentive payments are typically awarded upon achievement of certain performance metrics, including volume. The Company accounts for variable consideration using the most likely amount method. The Company utilizes forecasted sales data and rebate percentages specific to each customer agreement and updates its judgment of the amounts to which the customer is entitled each period. The Company enters into long term agreements with certain customers, under which it is obligated to make various up-front payments for which it expects to receive a benefit in excess of the cost over the term of the contract. These up-front payments are deferred and reflected in prepaid expenses and other current assets or other non-current assets on its consolidated balance sheet. Contract incentives are typically recognized as a reduction to revenue over the term of the customer agreement. Practical Expedients The Company sells primarily through its direct sales force. Any external sales commissions are expensed when incurred because the amortization period would be one year or less. External sales commission expense is included in selling, general and administrative expense in the consolidated statement of income. The Company accounts for shipping and handling activities as fulfillment costs. Accordingly, shipping and handling costs are classified as a component of cost of products sold while amounts billed to customers are classified as a component of net sales. The Company excluded from the measurement of the transaction price all taxes assessed by a government authority that are both imposed on and concurrent with a specific revenue producing transaction and collected from the customer, including sales taxes, value added taxes, excise taxes and use taxes. Accordingly, the tax amounts are not included in net sales. The Company will not adjust the promised consideration for the time value of money for contracts where the difference between the time of payment and performance is one year or less. Research and Development: Research and development expenditures are expensed as incurred. Restructuring Costs: Restructuring costs are recognized when the liability is incurred. The Company calculates severance obligations based on its standard customary practices. Accordingly, the Company records provisions for severance when probable and estimable and the Company has committed to the restructuring plan. In the absence of a standard customary practice or established local practice, liabilities for severance are recognized when incurred. If fixed assets are to be disposed of as a result of the Company’s restructuring efforts, the assets are written off when the Company commits to dispose of them and they are no longer in use. Depreciation is accelerated on fixed assets for the period of time the asset continues to be used until the asset ceases to be used. Other restructuring costs, including costs to relocate equipment, are generally recorded as the cost is incurred or the service is provided. Cash and Cash Equivalents: The Company considers all highly liquid temporary investments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents include certificates of deposit that can be readily liquidated without penalty at the Company’s option. Cash equivalents are carried at cost which approximates fair market value. Trade Receivables, Net: Trade accounts receivable, net, are stated at the amount the Company expects to collect, which is net of an allowance for sales returns and the estimated losses resulting from the inability of its customers to make required payments. When determining the collectability of specific customer accounts, a number of factors are evaluated, including: customer creditworthiness, past transaction history with the customer and changes in customer payment terms or practices. In addition, overall historical collection experience, current economic industry trends and a review of the current status of trade accounts receivable are considered when determining the required allowance for doubtful accounts. The Company has an allowance for doubtful accounts of $34.4 million and $16.9 million recorded at June 30, 2019 and 2018 , respectively, in trade receivables, net, on the consolidated balance sheet. The current year expense to adjust the allowance for doubtful accounts is recorded within selling, general and administrative expenses in the consolidated statement of income. The Company enters into factoring arrangements from time to time to sell trade receivables to third-party financial institutions. Sales of receivables are accounted for in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 860, Transfers and Servicing ("ASC 860"). Agreements which result in true sales of the transferred receivables, as defined in ASC 860, which occur when receivables are transferred without recourse to the Company, are reflected as a reduction of trade receivables, net on the consolidated balance sheets and the proceeds are included in the cash flows from operating activities in the consolidated statements of cash flows. Agreements that allow the Company to maintain effective control over the transferred receivables and which do not qualify as a true sale, as defined in ASC 860, are accounted for as secured borrowings and recorded in the consolidated balance sheets within trade receivables, net and short-term debt. The expenses associated with receivables factoring are recorded in the consolidated income statements within interest expense. As of June 30, 2019 , $24.7 million of trade receivables were factored qualifying as a true sale and the associated discount on sale was not significant. Factored receivables not qualifying as a true sale were accounted for as secured borrowings. As of June 30, 2018, none of the factoring arrangements the Company entered into qualified as true sales and thus were accounted for as secured borrowings. As of June 30, 2019 and 2018 , amounts factored recorded under trade receivables, net and short-term debt, were $152.7 million and $335.6 million , respectively. Inventories: Inventories are valued at the lower of cost, as determined by the first-in, first-out ("FIFO") method, or net realizable value. Inventory values using the FIFO method of accounting approximate replacement cost. Inventories are summarized at June 30, as follows: (in millions) 2019 2018 Raw materials and supplies $ 864.6 $ 640.8 Work in process 348.9 200.9 Finished goods 832.0 573.0 Less: inventory reserves (91.7 ) (55.9 ) Total inventories (1) $ 1,953.8 $ 1,358.8 (1) Increase primarily attributable to the acquisition of Bemis Company. Refer to Note 4, "Acquisitions," for more information about the Company's acquisition of Bemis. Property, Plant and Equipment, Net: Property, plant and equipment ("PP&E"), net is carried at cost less accumulated depreciation and impairment and includes expenditures for new facilities and equipment and those costs which substantially increase the useful lives or capacity of existing PP&E. Cost of constructed assets includes capitalized interest incurred during the construction period. Maintenance and repairs that do not improve efficiency or extend economic life are expensed as incurred. PP&E is depreciated using the straight-line method over the estimated useful lives of assets or, in the case of leasehold improvements and leased assets, over the period of the lease or useful life of the asset, whichever is shorter, as described below. The Company periodically reviews these estimated useful lives and, when appropriate, changes are made prospectively. Leasehold land Over lease term Land improvements Shorter of lease term or 20 - 33 years Buildings 14 - 40 years Plant and equipment 3 - 25 years Capital leases Shorter of lease term or 5 - 25 years For tax purposes, the Company generally uses accelerated methods of depreciation. The tax effect of the difference between book and tax depreciation has been provided for as deferred income taxes. Impairment of Long-lived Assets: The Company reviews long-lived assets, primarily PP&E and certain identifiable intangible assets with finite lives, for impairment when facts or circumstances indicate the carrying amount of an asset or asset group may not be recoverable. If impairment indicators are present and the estimated future undiscounted cash flows are less than the carrying value of the assets, the carrying values are reduced to the estimated fair value. Fair values are determined based on quoted market values, discounted cash flows or external appraisals, as applicable. Impairment losses recognized in the consolidated income statement were as follows: Years ended June 30, (in millions) 2019 2018 2017 Selling, general and administrative expenses (SG&A) $ 47.7 $ 0.4 $ — Restructuring related costs 27.4 4.0 22.4 Total impairment losses recognized in the consolidated income statements $ 75.1 $ 4.4 $ 22.4 Goodwill: Goodwill represents the excess of cost over the fair value of net assets acquired in a business combination. Goodwill is not amortized, but instead tested annually or whenever events and circumstances indicate an impairment may have occurred during the year. Among the factors that could trigger an impairment review are a reporting unit’s operating results significantly declining relative to its operating plan or historical performance, and competitive pressures and changes in the general markets in which it operates. All goodwill is assigned to a reporting unit, which is defined as the operating segment, or one level below the operating segment. The Company has 5 reporting units with goodwill that are assessed for potential impairment. In performing the required impairment tests, the Company has the option to first assess qualitative factors to determine if it is necessary to perform a quantitative assessment for goodwill impairment. If the qualitative assessment concludes that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value, a quantitative assessment is performed. A quantitative assessment primarily consists of a present value (discounted cash flow) method to determine the fair value of the reporting units with goodwill. The Company performs its annual impairment analysis in the fourth quarter of each year. A qualitative impairment analysis was performed on all reporting units for the fiscal year ended 2019, while a quantitative analysis was performed for fiscal years ended 2018 and 2017. The analysis concluded that goodwill was not impaired. Other Intangible Assets, Net: Contractual or separable intangible assets that have finite useful lives are amortized against income using the straight-line method over their estimated useful lives, with original periods ranging from one to 20 years. The straight-line method of amortization reflects an appropriate allocation of the costs of the intangible assets to earnings in proportion to the amount of economic benefits obtained by the Company in each reporting period. The Company tests finite-lived intangible assets for impairment when facts and circumstances indicate carrying value may not be recoverable from their undiscounted cash flows. If impaired, the assets are written down to fair value based on either discounted cash flows or appraised values. Costs incurred to develop software programs to be used solely to meet the Company's internal needs have been capitalized as computer software within other intangible assets. Financial Instruments: The Company recognizes all derivative instruments on the balance sheet at fair value. The impact on earnings from recognizing the fair values of these instruments depends on their intended use, their hedge designation and their effectiveness in offsetting changes in the fair values of the exposures they are hedging. Derivatives not designated as hedging instruments are adjusted to fair value through income. Depending on the nature of derivatives designated as hedging instruments, changes in the fair value are either offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings or recognized in shareholders’ equity through other comprehensive income until the hedged item is recognized. Gains or losses, if any, related to the ineffective portion of any hedge are recognized through earnings in the current period. Note 11 , " Derivative Instruments ," contains expanded details relating to specific derivative instruments included on the Company’s balance sheet, such as forward foreign currency exchange contracts, currency swap contracts, and interest rate swap arrangements. Employee Benefit Plans: The Company sponsors various defined contribution plans to which it makes contributions on behalf of employees. The expense under such plans was $39.9 million , $39.8 million and $39.9 million for the years ended June 30, 2019 , 2018 and 2017 , respectively. The Company sponsors a number of defined benefit plans that provide benefits to current and former employees. For the company-sponsored plans, the relevant accounting guidance requires that management make certain assumptions relating to the long-term rate of return on plan assets, discount rates used to determine the present value of future obligations and expenses, salary inflation rates, mortality rates and other assumptions. The Company believes that the accounting estimates related to its pension plans are critical accounting estimates because they are highly susceptible to change from period to period based on the performance of plan assets, actuarial valuations, market conditions and contracted benefit changes. The selection of assumptions is based on historical trends and known economic and market conditions at the time of valuation, as well as independent studies of trends performed by the Company’s actuaries. However, actual results may differ substantially from the estimates that were based on the critical assumptions. The Company recognizes the funded status of each defined benefit pension plan in the consolidated balance sheet. Each overfunded plan is recognized as an asset and each underfunded plan is recognized as a liability. Pension plan liabilities are revalued annually, or when an event occurs that requires remeasurement, based on updated assumptions and information about the individuals covered by the plan. Accumulated actuarial gains and losses in excess of a 10 percent corridor and the prior service cost are amortized on a straight-line basis from the date recognized over the average remaining service period of active participants or over the average life expectancy for plans with significant inactive participants. The service costs related to defined benefits are included in operating income. The other components of net benefit cost are presented in the consolidated income statements separately from the service cost component and outside operating income. Equity Method Investments: Investments in ordinary shares of companies, in which the Company believes it exercises significant influence over operating and financial policies, are accounted for using the equity method of accounting. Under this method, the investment is carried at cost and is adjusted to recognize the investor’s share of earnings or losses of the investee after the date of acquisition and is adjusted for impairment whenever it is determined that a decline in the fair value below the cost basis is other than temporary. See Note 7 , " Equity Method Investments ," for more information regarding the Company's equity method investments. Share-Based Compensation: Amcor has a variety of equity incentive plans. For employee awards with a service or market condition, compensation expense is recognized over the vesting period on a straight-line basis using the grant date fair value of the award and the estimated number of awards that are expected to vest. For awards with a performance condition, the Company must reassess the probability of vesting at each reporting period and adjust compensation cost based on its probability assessment. The Company also has cash-settled share-based compensation plans which are accounted for as liabilities. Such share-based awards are remeasured to fair value at each reporting period. The Company estimates forfeitures based on employee level, economic conditions, time remaining to vest and historical forfeiture experience. Income Taxes: The Company uses the asset and liability method to account for income taxes. Deferred income taxes reflect the future tax consequences of differences between the tax bases of assets and liabilities and their financial reporting amounts at each balance sheet date, based upon enacted income tax laws and tax rates. Income tax expense or benefit is provided based on earnings reported in the financial statements. The provision for income tax expense or benefit differs from the amounts of income taxes currently payable because certain items of income and expense included in the consolidated financial statements are recognized in different time periods by taxing authorities. Deferred tax assets, including operating loss, capital loss and tax credit carryforwards, are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that any portion of these tax attributes will not be realized. In addition, from time to time, management must assess the need to accrue or disclose uncertain tax positions for proposed adjustments from various tax authorities who regularly audit the Company in the normal course of business. In making these assessments, management must often analyze complex tax laws of multiple jurisdictions. Accounting guidance prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company records the related interest expense and penalties, if any, as tax expense in the tax provision. See Note 16 , " Income Taxes ," for more information.

New Accounting Guidance

New Accounting Guidance	12 Months Ended
	Jun. 30, 2019
New Accounting Guidance [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	New Accounting Guidance Recently Adopted Accounting Standards In May 2017, the FASB issued guidance that provides clarity and reduces diversity in practice, cost and complexity when applying existing accounting guidance for modifications to the terms or conditions of a share-based payment award. The amendments specify that all changes to the terms and conditions of a share-based payment award will require an entity to apply modification accounting, unless all of the following are met: (1) the fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified, (2) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified and (3) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments in ASU 2017-09 are effective for annual periods and interim periods within those annual periods, beginning after December 15, 2017, for all entities. Early adoption is permitted, including adoption in any interim period for which financial statements have not been issued. The new guidance is to be applied prospectively to awards modified on or after the adoption date. This guidance was effective for the Company on July 1, 2018 and did not have a material impact on the Company's consolidated financial statements. In January 2017, the FASB issued guidance that clarifies the definition of a business by adding a framework to assist entities in evaluating whether transactions should be accounted for as acquisitions of assets or businesses. In order to be considered a business under the new guidance, the assets in the transaction need to include an input and a substantive process that together significantly contribute to the ability to create outputs. Public business entities should apply the amendments in this update to annual periods beginning after December 15, 2017, including interim periods within those periods. The amendments in this update should be applied prospectively on or after the effective date. The guidance was effective for the Company on July 1, 2018. The Company followed the new guidance with respect to its acquisition of Bemis Company, Inc. and will apply the guidance to all future business combinations. In May 2014, the FASB issued new guidance which supersedes current revenue recognition requirements. This guidance is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company adopted the new revenue guidance on July 1, 2018 using the modified retrospective application transition method. The Company elected the practical expedient to apply the new revenue standard to only contracts that were not completed as of July 1, 2018. Adoption did not have an impact on the Company's financial statements, but did significantly impact the Company's disclosures for revenue. Refer to Note 2 , " Significant Accounting Policies ," for updated revenue disclosures which are required by the new guidance. Accounting Standards Not Yet Adopted In February 2018, the FASB issued guidance that requires the Company to disclose a description of the Company’s accounting policy for releasing income tax effects from accumulated other comprehensive income and whether the Company elects to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act (‘‘The Act’’), along with information about other income tax effects that are reclassified. For all entities, the guidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted for periods for which financial statements have not yet been issued. Entities can choose whether to apply the amendments retrospectively to each period in which the effect of the Act is recognized or to apply the amendments in the period of adoption. This guidance will be effective for the Company on July 1, 2019. The Company does not expect the standard to have a material impact on its consolidated financial statements. In August 2017, the FASB issued guidance which simplifies existing guidance in order to allow companies to more accurately present the economic effects of risk management activities in the financial statements. For public business entities, the amendments in ASU 2017-12 are effective for financial statements issued for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. This guidance will be effective for the Company on July 1, 2019 using the modified respective approach, with the exception of presentation and disclosure guidance which will be adopted prospectively. The Company does not expect the standard to have a material impact on its consolidated financial statements. In June 2016, the FASB issued guidance which requires financial assets or a group of financial assets measured at amortized cost basis to be presented at the net amount expected to be collected when finalized. The allowance for credit losses is a valuation account that will be deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. This guidance affects loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables and any other financial assets not excluded from the scope that have the contractual right to receive cash. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The guidance will be effective for the Company on July 1, 2020 and will be adopted using the modified retrospective approach. The Company is currently assessing the impact that the adoption of this new guidance will have on its consolidated financial statements. In February 2016, the FASB issued guidance that required lessees to put most leases on their balance sheets but recognize expenses on their income statements in a manner similar to today’s accounting. The guidance also eliminates today’s real estate-specific provisions and changes the guidance on sale-leaseback transactions, initial direct costs and lease executory costs for all entities. Lease classification will determine how to recognize lease-related revenue and expense. The Company will elect the optional transition method that allows for a cumulative-effect adjustment in the period of adoption and will not restate prior periods. The Company has formed a cross-functional project team to implement the new guidance. The project team is working to implement a lease accounting software solution and resolve the vendor's identified software issues. The Company will adopt the guidance on July 1, 2019. Based on our current lease portfolio, adoption of the standard will result in an increase in operating lease assets and liabilities in a range of $600 million to $800 million with an immaterial impact on our Consolidated Statement of Income; however, this estimate is subject to change as we finalize our implementation. In addition, we expect to de-recognize existing deferred gains on sale leasebacks of approximately $75.0 million as a cumulative-effect adjustment to retained earnings as of July 1, 2019.

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	Acquisitions Year ended June 30, 2019 Bemis Company, Inc. On June 11, 2019, the Company completed the acquisition of 100% of the outstanding shares of Bemis Company, Inc ("Bemis"), a global manufacturer of flexible packaging products based in the United States. Pursuant to the Transaction Agreement, dated as of August 6, 2018, each outstanding share of Bemis common stock that was issued and outstanding upon completion of the transaction was converted into the right to receive 5.1 ordinary shares of the Company traded on the NYSE. The following table summarizes the fair value of consideration exchanged: Bemis shares outstanding at June 11, 2019 (in millions) 91.7 Share Exchange Ratio 5.1 Price per Share (Based on Amcor’s closing share price on June 11, 2019) 11.18 Total Equity Consideration 5,229.6 The acquisition of Bemis positions the Company as a global leader in consumer packaging with a comprehensive global footprint in flexible packaging and greater scale in key regions of North America, Latin America, Asia Pacific and Europe, along with industry-leading research and development capabilities. The Bemis acquisition contributed $215.4 million in net sales and a $12.4 million net loss, which includes transaction related costs, to the Company's consolidated fiscal year 2019 results. The acquisition of Bemis was accounted for as a business combination in accordance with ASC 805, "Business Combinations," which required allocation of the purchase price to the estimated fair values of assets acquired and liabilities assumed in the transaction. The following is a summary of the preliminary allocation of the purchase price: (in millions) Cash and cash equivalents $ 3.3 Trade receivables 436.4 Inventories 665.1 Prepaid expenses and other current assets 83.8 Assets held for sale 415.6 Property, plant and equipment 1,390.7 Deferred tax assets 35.5 Other intangible assets 2,030.2 Other non-current assets 34.5 Total identifiable assets acquired 5,095.1 Current portion of long-term debt 1.7 Short-term debt 8.6 Trade payables 287.7 Accrued employee costs 158.0 Other current liabilities 275.9 Liabilities held for sale 21.9 Long-term debt, less current portion 1,365.3 Deferred tax liabilities 782.6 Employee benefit obligation 62.6 Other non-current liabilities 38.9 Total liabilities assumed 3,003.2 Net identifiable assets acquired 2,091.9 Goodwill 3,137.7 Net assets acquired $ 5,229.6 The following table details the preliminary identifiable intangible assets acquired from Bemis, their fair values and estimated useful lives: Fair Value Weighted-average Estimated Useful Life (in millions) (Years) Customer relationships $ 1,730.0 15 Technology 131.0 7 Other 169.2 8 Total other intangible assets $ 2,030.2 The initial purchase price allocation is preliminary in nature and subject to adjustments, which could be material. Any necessary adjustments will be finalized within one year from the date of acquisition. The preliminary allocation of the purchase price resulted in $3,137.7 million of goodwill for the Flexibles Segment, which is not tax deductible. The goodwill on acquisition represents the future economic benefit expected to arise from other intangible assets acquired that do not qualify for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. As the Company finalizes the valuation of assets acquired and liabilities assumed, it will determine to which reporting units within the Company's segments any changes in goodwill should be recorded. The fair value measurement of tangible and intangible assets and liabilities was based on significant inputs not observable in the market and thus represent Level 3 measurements within the fair value measurement hierarchy. Level 3 fair market values were determined using a variety of information, including estimated future cash flows, appraisals and market comparables. Closing of the Bemis acquisition was conditional upon the receipt of regulatory approvals, approval by both Amcor and Bemis shareholders, and satisfaction of other customary conditions. In order to satisfy certain regulatory approvals, the Company was required to divest three of Bemis' medical packaging facilities located in the United Kingdom and Ireland ("EC Remedy") and three Amcor medical packaging facilities in the United States ("U.S. Remedy"). The U.S. Remedy was completed during the fourth quarter of 2019 and the Company received $214.2 million resulting in a gain of $159.1 million which is included in other income, net in the consolidated statement of income. See Note 5 , " Discontinued Operations ," for more information on the EC Remedy. The following unaudited pro forma information has been prepared as if the acquisition of Bemis and the sale of the EC Remedy and U.S. Remedy had occurred as of July 1, 2017. The unaudited pro forma information combines the historical results of Amcor and Bemis. Years ended June 30, (in millions) 2019 2018 Net sales $ 12,972.4 $ 13,146.3 Income from continuing operations $ 565.5 $ 535.0 Pro forma adjustments to net sales are as follows: • Excludes net sales of the EC Remedy and U.S. Remedy. Pro forma adjustments to income from continuing operations attributable to Amcor plc are as follows: • Excludes income from the EC Remedy which has been accounted for as a discontinued operation and the U.S. Remedy which has been reported in U.S. GAAP income from continuing operations; • excludes acquisition related charges; • includes preliminary acquisition accounting adjustments, including amortization and depreciation adjustments as a result of the fair value adjustment to property, plant and equipment; and • excludes the impact on net income attributable to purchase accounting related inventory effects and sales backlog amortization given these charges do not have a continuing impact on the consolidated results. The pro forma results are not necessarily indicative of the actual results that would have occurred had the acquisition been in effect for the periods presented, nor is it intended to be a projection of future results. For example, the pro forma results do not include the expected synergies from the transactions, nor the related costs to achieve. Year ended June 30, 2017 Sonoco's Blow Molding Operations On November 8, 2016, the Company acquired the North American blow molding operations of Sonoco Products Company ("Sonoco"), a global packaging company based in the United States, for the purchase price of $271.7 million in cash. The Company acquired six production sites in the United States and one in Canada and customer relationships. The acquisition allowed the Company to expand its operations in the personal care and specialty food market. The acquisition of Sonoco's blow molding operations was accounted for as a business combination in accordance with ASC 805, Business Combinations, which required allocation of the purchase price to the estimated fair values of assets acquired and liabilities assumed in the transaction. The following is a summary of the final allocation of the purchase price: (in millions) Trade receivables $ 35.8 Inventories 13.5 Property, plant and equipment 45.7 Deferred tax assets 1.9 Other intangible assets 11.5 Total identifiable assets acquired 108.4 Trade payables 19.4 Other current liabilities 4.4 Deferred tax liabilities 1.9 Other non-current liabilties 4.0 Total liabilities assumed 29.7 Net identifiable assets acquired 78.7 Goodwill 193.0 Net assets acquired $ 271.7 The following table details the identifiable intangible assets acquired from Sonoco, their fair values and estimated useful lives: Fair Value Weighted-average Estimated Useful Life (in millions) (Years) Customer relationships $ 11.5 12 Total other intangible assets $ 11.5 The allocation of the purchase price resulted in $193.0 million of goodwill for the Rigid Packaging segment, which is not tax deductible. The goodwill on acquisition is primarily attributable to expected synergies available to the consolidated entity upon the integration of the businesses into the Company, as well as benefits derived from the acquired workforce and other intangible assets that cannot be separately recognized. The fair value measurement of tangible and intangible assets and liabilities were based on significant inputs not observable in the market and thus represent Level 3 measurements within the fair value measurement hierarchy. Level 3 fair market values were determined using a variety of information, including estimated future cash flows, appraisals and market comparables. Pro forma results of operations have not been presented because they are not material to the consolidated income statements. Discma On June 16, 2017, the Company acquired the remaining 50% ownership interest in Discma AG ("Discma") for a total consideration of $25.1 million , with $10.3 million payable upon close and $14.8 million deferred and contingent on future cash flows. Prior to this acquisition, the fair value of the Company's equity interest in Discma was $22.0 million , resulting in a remeasurement gain of $18.6 million , which was recorded in other income, net in the consolidated income statement for the year ended June 30, 2017. The fair value of the equity interest in Discma was based on significant inputs not observable in the market and thus represent Level 3 measurements within the fair value hierarchy.

Restructuring and Related Activities [Abstract]
Restructuring and Related Activities Disclosure [Text Block]	Restructuring Plans 2019 Bemis Integration Plan In connection with the acquisition of Bemis, the Company initiated restructuring activities in the fourth quarter of 2019 aimed at integrating and optimizing the combined organization. As previously announced, the Company continues to target realizing approximately $180 million of pre-tax synergies driven by procurement, supply chain, and general and administrative savings by the end of fiscal year 2022. The total Plan pre-tax cost is estimated at $200 million , with cash payments estimated at $150 million . The 2019 Bemis Integration Plan relates to the Flexibles segment and Corporate and is expected to be completed by the end of fiscal year 2022. In the fourth quarter of 2019, the Company incurred $47.9 million of pre-tax restructuring expenses in the Flexibles segment related to this Plan, primarily related to employee termination costs. There were no cash payments associated with the plan in fiscal year 2019. 2018 Rigid Packaging Restructuring Plan On August 21, 2018, the Company announced a restructuring plan in Amcor Rigid Packaging ("2018 Rigid Packaging Restructuring Plan") aimed at reducing structural costs and optimizing the footprint. The Plan includes the closures of manufacturing facilities and headcount reductions to achieve manufacturing footprint optimization and productivity improvements as well as overhead cost reductions. The Company's total pre-tax restructuring costs are expected to be approximately $95.0 million with the main component being cost to exit manufacturing facilities and employee related costs. The Company estimates that approximately $65.0 million of the $95.0 million total costs will result in cash expenditures. Cash payments for fiscal year 2019 were $30.3 million . The Plan is expected to be completed in fiscal year 2020. 2016 Flexibles Restructuring Plan On June 9, 2016, the Company announced a major initiative ("2016 Flexibles Restructuring Plan") to optimize the cost base and drive earnings growth in the Flexibles segment. This initiative was designed to accelerate the pace of adapting the organization within developed markets through footprint optimization to better align capacity with demand, increase utilization and improve the cost base and streamlining the organization and reducing complexity, particularly in Europe, to enable greater customer focus and speed to market. As part of the 2016 Flexibles Restructuring Plan, the Company has closed eight manufacturing facilities and reduced headcount at certain facilities. The Company's total pre-tax restructuring costs were approximately $230.8 million , with approximately $166.7 million in employee termination costs, $31.4 million in fixed asset impairment costs and $32.7 million in other costs, which primarily represent the cost to dismantle equipment and terminate existing lease contracts.

During the years ended June 30, 2019 , 2018 and 2017 the Company received dividends of $8.2 million (HKD 63.7 million ), $8.4 million (HKD 65.9 million ) and $6.5 million (HKD 50.4 million ), respectively, from AMVIG. The Company reviews its investment in affiliated companies for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Due to impairment indicators present in each of the years presented, the Company performed an impairment test by comparing the carrying value of its investment in AMVIG to its fair value, which was determined based on AMVIG's quoted share price. The fair value of the investment dropped below its carrying value during fiscal years 2018 and 2019, and therefore the Company recorded an other-than-temporary impairment of $14.0 million and $36.5 million , respectively, to bring the value of its investment to fair value.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Fair Value Measurements The fair values of the Company's financial assets and financial liabilities listed below reflect the amounts that would be received to sell the assets or paid to transfer the liabilities in an orderly transaction between market participants at the measurement date (exit price). The Company's non-derivative financial instruments primarily include cash and cash equivalents, trade receivables, trade payables, short-term debt and long-term debt. At June 30, 2019 and 2018 , the carrying value of these financial instruments, excluding long-term debt, approximates fair value because of the short-term maturities of these instruments. Fair value disclosures are classified based on the fair value hierarchy. Level 1 fair value measurements represent exchange-traded securities which are valued at quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access as of the reporting date. Level 2 fair value measurements are determined using input prices that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data. Level 3 fair value measurements are determined using unobservable inputs, such as internally developed pricing models for the asset or liability due to little or no market activity for the asset or liability. The fair value of long-term debt with variable interest rates approximates its carrying value. The fair value of the Company's long-term debt with fixed interest rates is based on market prices, if available, or expected future cash flows discounted at the current interest rate for financial liabilities with similar risk profiles. The carrying values and estimated fair values of long-term debt with fixed interest rates (excluding capital leases) were as follows: June 30, 2019 June 30, 2018 Carrying Value Fair Value Carrying Value Fair Value (in millions) (Level 2) (Level 2) Total long-term debt with fixed interest rates (excluding commercial paper and capital leases) $ 2,955.6 $ 3,041.3 $ 2,781.9 $ 2,841.5 Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis Additionally, the Company measures and records certain assets and liabilities, including derivative instruments and contingent purchase consideration liabilities, at fair value. The following table summarizes the fair value of these instruments, which are measured at fair value on a recurring basis, by level, within the fair value hierarchy: June 30, 2019 (in millions) Level 1 Level 2 Level 3 Total Assets Commodity contracts $ — $ — $ — $ — Forward exchange contracts — 5.5 — 5.5 Interest rate swaps — 32.8 — 32.8 Total assets measured at fair value $ — $ 38.3 $ — $ 38.3 Liabilities Contingent purchase consideration liabilities $ — $ — $ 13.6 $ 13.6 Commodity contracts — 4.6 — 4.6 Forward exchange contracts — 9.3 — 9.3 Interest rate swaps — — — — Total liabilities measured at fair value $ — $ 13.9 $ 13.6 $ 27.5 June 30, 2018 (in millions) Level 1 Level 2 Level 3 Total Assets Commodity contracts $ — $ 1.6 $ — $ 1.6 Forward exchange contracts — 7.2 — 7.2 Interest rate swaps — 22.3 — 22.3 Total assets measured at fair value $ — $ 31.1 $ — $ 31.1 Liabilities Contingent purchase consideration liabilities $ — $ — $ 14.6 $ 14.6 Commodity contracts — 0.5 — 0.5 Forward exchange contracts — 6.6 — 6.6 Interest rate swaps — 1.3 — 1.3 Total liabilities measured at fair value $ — $ 8.4 $ 14.6 $ 23.0 The fair value of the commodity contracts was determined using a discounted cash flow analysis based on the terms of the contracts and observed market forward prices discounted at a currency-specific rate. Forward exchange contract fair values were determined based on quoted prices for similar assets and liabilities in active markets using inputs such as currency rates and forward points. The fair value of the interest rate swaps was determined using a discounted cash flow method based on market-based swap yield curves, taking into account current interest rates. The fair value of the contingent purchase consideration liabilities was determined for each arrangement individually. The fair value was determined using the income approach with significant inputs that are not observable in the market. Key assumptions include the discount rates consistent with the level of risk of achievement and probability adjusted financial projections. The expected outcomes are recorded at net present value, which requires adjustment over the life for changes in risks and probabilities. The following table sets forth a summary of changes in the value of the Company's Level 3 financial liabilities: June 30, (in millions) 2019 2018 2017 Fair value at the beginning of the year $ 14.6 $ 27.6 $ 36.1 Additions due to acquisitions — — 12.6 Changes in fair value of Level 3 liabilities — 0.8 (2.4 ) Payments (1.0 ) (13.0 ) (18.6 ) Foreign currency translation — (0.8 ) (0.1 ) Fair value at the end of the year $ 13.6 $ 14.6 $ 27.6 The fair value of contingent purchase consideration liabilities is included in other current liabilities and other non-current liabilities in the consolidated balance sheets. The change in fair value of the contingent purchase consideration liabilities, which was included in other income, net is due to the passage of time and changes in the probability of achievement used to develop the estimate.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Derivative Instruments Amcor periodically uses derivatives and other financial instruments to hedge exposures to interest rate, commodity and currency risks. The Company does not hold or issue financial instruments for speculative or trading purposes. For hedges that meet the hedge accounting criteria, the Company, at inception, formally designates and documents the instrument as a fair value hedge or a cash flow hedge of a specific underlying exposure. On an ongoing basis, the Company assesses and documents that its hedges have been and are expected to continue to be highly effective. Interest Rate Risk The Company's policy is to manage exposure to interest rate risk by maintaining a mixture of fixed-rate and variable-rate debt, monitoring global interest rates and, where appropriate, hedging floating interest rate exposure or debt at fixed interest rates through the use of interest rate swaps. Fixed-for-floating interest rate swaps are accounted for as fair value hedges so the changes in the fair value of both the hedging instruments and the underlying debt obligations are immediately recognized in interest expense. As of June 30, 2019 and 2018 , the total notional amount of the Company's receive-fixed/pay-variable interest rate swaps was $841.1 million and $586.7 million , respectively. Foreign Currency Risk Amcor manufactures and sells its products and finances operations in a number of countries throughout the world and, as a result, is exposed to movements in foreign currency exchange rates. The purpose of the Company's foreign currency hedging program is to manage the volatility associated with the changes in exchange rates. To manage this exchange rate risk, the Company utilizes forward contracts. Contracts that qualify for hedge accounting are designated as cash flow hedges of certain forecasted transactions denominated in foreign currencies. The effective portion of the changes in fair value of these instruments is reported in accumulated other comprehensive income (loss) ("AOCI") and reclassified into earnings in the same financial statement line item and in the same period or periods during which the related hedged transactions affect earnings. The ineffective portion is immediately recognized in the consolidated income statements. Changes in the fair value of forward contracts that have not been designated as hedging instruments are reported in the accompanying consolidated income statements. As of June 30, 2019 and 2018 , the notional amount of the outstanding forward contracts was $1.0 billion and $1.1 billion , respectively. The Company also manages its currency exposure related to the net assets of its foreign operations primarily through borrowings denominated in the relevant currency. Foreign currency gains and losses from the remeasurement of external borrowings designated as net investment hedges of a foreign operation are recognized in AOCI, to the extent that the hedge is effective. The ineffective portion is immediately recognized in other non-operating income (loss), net in the unaudited condensed consolidated income statements. When a hedged net investment is disposed of, a percentage of the cumulative amount recognized in AOCI in relation to the hedged net investment is recognized in the consolidated income statements as part of the profit or loss on disposal. At the beginning of fiscal year 2019, the Company designated non-derivative instruments with a carrying value of $1.4 billion as foreign currency net investment hedges. During the three months ended December 31, 2018, the Company de-designated €850.0 million of its Euro-denominated notes, which were previously designated as a net investment hedge in its European subsidiaries. The portion of the net investment hedge recorded through the point of de-designation is included in AOCI and will be reclassified into earnings only upon the sale or liquidation of the related subsidiaries. In addition, during the three months ended December 31, 2018, the Company settled loans that were denominated in NZD and HKD, of which NZD 95.0 million and HKD 174.6 million , respectively, were previously designated as net investment hedges. The net investment hedges recorded through the point of settlement are included in AOCI and will be reclassified into earnings only upon the sale or liquidation of the related subsidiaries. As of Jun 30, 2019 the carrying value of US commercial paper issued which is designated as a net investment hedge was $67.0 million . The Company did not have any net investment hedges in place as of June 30, 2018 and 2017. Commodity Risk Certain raw materials used in Amcor's production processes are subject to price volatility caused by weather, supply conditions, political and economic variables and other unpredictable factors. To manage the volatility in earnings due to price fluctuations, the Company utilizes fixed price swaps. Changes in the fair value of commodity hedges are recognized in AOCI. The cumulative amount of the hedge is recognized in the consolidated income statements when the forecast transaction is realized. At June 30, 2019 and 2018 , the Company had the following outstanding commodity contracts that were entered into to hedge forecasted purchases: June 30, 2019 June 30, 2018 Commodity Volume Volume Aluminum 29,342 tons 18,239 tons The following tables provide the location of derivative instruments in the consolidated balance sheet: June 30, (in millions) Balance Sheet Location 2019 2018 Assets Derivatives in cash flow hedging relationships: Commodity contracts Other current assets $ — $ 1.6 Forward exchange contracts Other current assets 2.4 0.7 Derivatives not designated as hedging instruments: Forward exchange contracts Other current assets 2.7 6.5 Total current derivative contracts 5.1 8.8 Derivatives in fair value hedging relationships: Interest rate swaps Other non-current assets 32.8 22.3 Derivatives not designated as hedging instruments: Forward exchange contracts Other non-current assets 0.4 — Total non-current derivative contracts 33.2 22.3 Total derivative asset contracts $ 38.3 $ 31.1 Liabilities Derivatives in cash flow hedging relationships: Commodity contracts Other current liabilities $ 4.6 $ 0.5 Forward exchange contracts Other current liabilities 1.5 1.7 Derivatives not designated as hedging instruments: Forward exchange contracts Other current liabilities 7.1 4.9 Total current derivative contracts 13.2 7.1 Derivatives in cash flow hedging relationships: Forward exchange contracts Other non-current liabilities 0.3 — Derivatives in fair value hedging relationships: Interest rate swaps Other non-current liabilities — 1.3 Derivatives not designated as hedging instruments: Forward exchange contracts Other non-current liabilities 0.4 — Total non-current derivative contracts 0.7 1.3 Total derivative liability contracts $ 13.9 $ 8.4 In addition to the fair value associated with derivative instruments noted in the table above, the Company had a carrying value of $67.0 million and nil associated with non-derivative instruments designated as foreign currency net investment hedges as of June 30, 2019 and 2018, respectively. The designated foreign currency-denominated debt is included in long-term debt in the consolidated balance sheet. Certain derivative financial instruments are subject to master netting arrangements and are eligible for offset. The Company has made an accounting policy election not to offset the fair values of these instruments within the consolidated balance sheets.

Weighted-average assumptions used to determine benefit obligations at year end were: June 30, 2019 2018 2017 Discount rate 2.5 % 2.3 % 2.1 % Rate of compensation increase 2.1 % 1.9 % 1.8 % Weighted-average assumptions used to determine net periodic benefit cost at year end were: June 30, 2019 2018 2017 Discount rate 2.3 % 2.1 % 2.0 % Rate of compensation increase 1.9 % 1.8 % 1.7 % Expected long-term rate of return on plan assets 3.6 % 4.1 % 4.3 % Where funded, the Company and, in some countries, the employees make cash contributions into the pension fund. In the case of unfunded plans, the Company is responsible for benefit payments as they fall due. Plan funding requirements are generally determined by local regulation and/or best practice and differ between countries. The local statutory funding positions are not necessarily consistent with the funded status disclosed on the consolidated balance sheets. For any funded plans in deficit (as measured under local country guidelines), the Company agrees with the trustees and plan fiduciaries to undertake suitable funding programs to provide additional contributions over time in accordance with local country requirements. Contributions to the Company's defined benefit pension plans, not including unfunded plans, are expected to be $24.7 million over the next fiscal year. The following benefit payments for the succeeding five fiscal years and thereafter, which reflect expected future service, as appropriate, are expected to be paid: (in millions) 2020 $ 84.9 2021 91.5 2022 87.7 2023 89.4 2024 92.1 2025-2029 471.0 The ERISA Benefit Plan Committee in the United States, the Pension Plan Committee in Switzerland and the Trustees of the pension plans in Canada, Ireland and UK establish investment policies and strategies for the Company's pension plan assets and are required to consult with the Company on changes to their investment policy. In developing the expected long-term rate of return on plan assets at each measurement date, the Company considers the plan assets' historical returns, asset allocations, and the anticipated future economic environment and long-term performance of the asset classes. While appropriate consideration is given to recent and historical investment performance, the assumption represents management's best estimate of the long-term prospective return.

Corporate debt securities: Valued using market inputs including benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids, offers and reference data including market research publications. Inputs may be prioritized differently at certain times based on market conditions. Real estate: Valued at the closing prices reported in the active market in which the listed real estate funds are traded. Cash and cash equivalents: Consist of cash on deposit with brokers and short-term money market funds and are shown net of receivables and payables for securities traded at period end but not yet settled. All cash and cash equivalents are stated at cost, which approximates fair value. Other: Level 1: Mutual funds. A daily asset value is available for these assets. Level 2: Assets held in diversified growth funds, pooled funds, financing funds and derivatives, where the value of the assets are determined by the investment managers or an external valuer based on the probable value of the underlying assets. Level 3: Indemnified plan assets and a buy-in policy, insurance contacts and pooled funds (equity, credit, macro-orientated, multi-strategy, cash and other). The value of indemnified plan assets and the buy-in policy are determined based on the value of the liabilities that the assets cover.

To manage the market price risk, the Company has entered into forward contracts for the purchase of its ordinary shares. As of June 30, 2019 , the Company has entered into forward contracts that mature in June 2020 to purchase 1.0 million shares at a price of $11.00 . As of June 30, 2018 , the Company had entered into forward contracts that matured in May 2019 and resulted in the purchase of 2.5 million shares at a price of AUD 13.80 . The forward contracts to purchase the Company's own shares are classified as a liability. Equity is reduced by an amount equal to the fair value of the shares at inception. The carrying value of the forward contracts at each reporting period was determined based on the present value of the cost required to settle the contract.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes Amcor plc is a tax resident of the United Kingdom of Great Britain and Northern Ireland. The ultimate parent of the Company at June 30, 2018 and 2017 was Amcor Limited, which was a tax resident in Australia. The components of income before income taxes and equity in income (loss) of affiliated companies were as follows: Years ended June 30, (in millions) 2019 2018 2017 Domestic 31.7 $ (206.6 ) $ (26.0 ) Foreign 572.4 929.5 741.8 Total income before income taxes and equity in income (loss) of affiliated companies $ 604.1 $ 722.9 $ 715.8 Income tax expense consisted of the following: Years ended June 30, (in millions) 2019 2018 2017 Current tax Domestic 7.2 $ 0.2 $ 0.2 Foreign 91.5 192.1 177.8 Total current tax 98.7 192.3 178.0 Deferred tax Domestic (3.2 ) (21.3 ) 8.5 Foreign 76.0 (52.2 ) (37.6 ) Total deferred tax 72.8 (73.5 ) (29.1 ) Income tax expense $ 171.5 $ 118.8 $ 148.9 The following is a reconciliation of income tax computed at the UK statutory tax rate of 19% for fiscal year 2019 and 30% for fiscal years 2018 and 2017, to income tax expense. Years ended June 30, (in millions) 2019 2018 2017 Income tax expense at statutory rate $ 114.8 $ 216.9 $ 214.7 Foreign tax rate differential 59.5 (40.8 ) (69.9 ) Tax-exempt income — 5.7 2.6 Non-deductible expenses 5.6 (7.7 ) (12.1 ) Tax law changes (2.3 ) (52.9 ) 0.7 Change in valuation allowance (5.9 ) 5.3 12.0 Other (0.2 ) (7.7 ) 0.9 Income tax expense $ 171.5 $ 118.8 $ 148.9 For fiscal year 2019, the Company's effective tax rate for the year was higher than its UK statutory tax rate primarily due to pretax income being earned in jurisdictions outside of the UK where the applicable tax rates are higher than the UK statutory tax rate. Amcor operates in over forty different jurisdictions with a wide range of statutory tax rates. The tax expense from operating in non-UK jurisdictions in excess of the UK statutory tax rate is included in the line "Foreign tax rate differential" in the above tax rate reconciliation table. For fiscal year 2019, the Company's effective tax rate was 28.4% as compared to the prior year effective tax rates of 16.4% and 20.8% for fiscal years 2018 and 2017, respectively. For changes in the tax law, refer to the below section titled "The Act." Significant components of deferred tax assets and liabilities are as follows: June 30, (in millions) 2019 2018 Deferred tax assets Trade receivables $ — $ 4.5 Inventories 6.3 5.9 Accrued employee benefits 103.1 66.6 Derivatives — 17.7 Provisions 14.1 — Net operating loss carryforwards 275.0 246.4 Tax credit carryforwards 49.9 48.6 Accruals and other 122.7 75.9 Total deferred tax assets 571.1 465.6 Valuation allowance (290.9 ) (270.5 ) Net deferred tax assets 280.2 195.1 Deferred tax liabilities Property, plant and equipment (329.2 ) (184.3 ) Other intangible assets (638.5 ) (63.4 ) Trade receivables (6.7 ) — Derivatives (20.4 ) — Undistributed foreign earnings (106.2 ) (24.2 ) Total deferred tax liabilities (1,101.0 ) (271.9 ) Net deferred tax liability (820.8 ) (76.8 ) Deferred tax assets 190.9 70.7 Deferred tax liabilities (1,011.7 ) (147.5 ) Net deferred tax liability $ (820.8 ) $ (76.8 ) The Company maintains a valuation allowance on net operating losses and other deferred tax assets in jurisdictions for which it does not believe it is more-likely-than-not to realize those deferred tax assets based upon all available positive and negative evidence, including historical operating performance, carryback periods, reversal of taxable temporary differences, tax planning strategies and earnings expectations. The Company's valuation allowance increased by $20.4 million , increased by $5.3 million and decreased by $12.0 million for fiscal year 2019, 2018 and 2017, respectively. The increase of the Company’s valuation allowance for the year ended June 30, 2019 is attributed mainly to the valuation allowance taken over from Bemis of $33.7 million partially offset by net release of valuation allowance of $5.9 million and foreign exchange rate revaluation of $7.4 million . As of June 30, 2019, the Company has UK net operating losses (tax effected) and tax credits of approximately $4.3 million that do not expire. The Company has non-UK net operating losses (tax effected) and other tax attribute carryforwards of $320.6 million , the majority of which do not expire. The Company recorded valuation allowances against deferred tax assets associated with these net operating losses and tax credits. The benefits of these carryforwards are dependent upon the generation of taxable income in the jurisdictions where they arose. Amcor considers the following factors, among others, in evaluating its plans for indefinite reinvestment of its subsidiaries' earnings: (i) the forecasts, budgets and financial requirements of the Company and its subsidiaries, both for the long term and for the short term; and (ii) the tax consequences of any decision to reinvest earnings of any subsidiary. The Company has not provided deferred taxes on approximately $628.0 million of earnings in certain foreign subsidiaries because such earnings are indefinitely reinvested in its international operations. Upon distribution of such earnings in the form of dividends or otherwise, the Company may be subject to incremental foreign tax. It is not practicable to estimate the amount of foreign tax that might be payable. A cumulative deferred tax liability of $106.2 million has been recorded attributable to undistributed earnings that the Company has deemed are no longer indefinitely reinvested. This also includes the tax liability that the Company estimates will be due upon the divestitures required by the national regulators to approve the merger with Bemis. The remaining undistributed earnings of the Company's subsidiaries are not deemed to be indefinitely reinvested and can be repatriated at no tax cost. Accordingly, there is no provision for income or withholding taxes on these earnings. The Company accounts for its uncertain tax positions in accordance with ASC 740, "Income Taxes." At June 30, 2019 and 2018, unrecognized tax benefits totaled $102.6 million and $74.5 million , respectively, all of which would favorably impact the effective tax rate if recognized. The Company recognizes interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the years ended June 30, 2019, 2018 and 2017, the Company accrued $13.8 million , $2.9 million , and $4.6 million of interest and penalties related to these uncertain tax positions, respectively. The Company does not currently anticipate that the total amount of unrecognized tax benefits will result in material changes to its financial position within the next 12 months. A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years presented is as follows: June 30, (in millions) 2019 2018 2017 Balance at the beginning of the year $ 74.5 $ 65.1 $ 56.5 Additions based on tax positions related to the current year 12.5 6.6 1.4 Additions for tax positions of prior years 8.2 8.9 8.8 Reductions for tax positions from prior years (3.7 ) (5.3 ) — Reductions for settlements (5.8 ) — — Reductions due to lapse of statute of limitations (12.8 ) (0.8 ) (1.6 ) Additions related to acquisitions 29.7 — — Balance at the end of the year $ 102.6 $ 74.5 $ 65.1 The Company conducts business in a number of tax jurisdictions and, as such, is required to file income tax returns in multiple jurisdictions globally. The years 2015 through 2017 remain open for examination by the United States Internal Revenue Service ("IRS"), the year 2018 remains open for examination by Her Majesty’s Revenue & Customs ("HMRC") and the years 2011-2018 are currently subject to audit or remain open for examination in various US states and non-US tax jurisdictions. The Company believes that its income tax reserves are adequately maintained taking into consideration both the technical merits of its tax return positions and ongoing developments in its income tax audits. However, the final determination of the Company's tax return positions, if audited, is uncertain and therefore there is a possibility that final resolution of these matters could have a material impact on the Company's results of operations or cash flows. U.S. Tax Cuts and Jobs Act ("The Act") On December 22, 2017, The Act was signed into law. This legislation includes significant changes in U.S. tax law, including a reduction in the corporate tax rates and the creation of a territorial tax system with a one-time mandatory tax on previously deferred foreign earnings of U.S.-held foreign subsidiaries. The legislation reduced the U.S. corporate tax rate from 35% to 21% for tax years beginning after December 31, 2017. As a result of the enacted law, the Company was required to revalue deferred tax assets and liabilities existing as of December 31, 2017 from the 35% federal rate in effect through the end of 2017, to the new 21% rate.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Share-based Compensation The Company's equity incentive plans include grants of share options, restricted shares/ units, performance shares, performance rights and share rights to directors, officers and employees. In certain countries and in selected cases, cash equivalent awards are provided in the event that the issuance of equity awards is not compliant with local legislation and tax laws. Cash-Settled Awards Cash-settled awards may be granted to directors, officers and employees of the Company in lieu of, or in addition to, participation in other programs. Such awards are accounted for as liabilities and are remeasured to fair value at each balance sheet date. Liabilities for cash-settled share-based compensation are as follows: June 30, (in millions) 2019 2018 Total carrying amount of liabilities for cash settled arrangements $ 2.7 $ 4.1 During fiscal years 2019, 2018 and 2017, the Company paid $2.3 million , $1.6 million and $3.9 million in cash, respectively, to settle these plans. Equity-Settled Awards Share Options There were no share options granted in fiscal year 2019 as they were deferred due to the transaction with Bemis. In fiscal year 2018, share options were granted to officers and employees. The exercise price for shares options was set at the time of grant. The requisite service period for outstanding share options in fiscal year 2019 ranges from three to four years. The awards are also subject to performance and market conditions. At vesting, share options can be exercised and converted to ordinary shares on a one-for-one basis, subject to payment of the exercise price. The maximum contractual term of the share options in fiscal year 2019 ranges from six to seven years from the grant date. The fair value of the share options granted in fiscal year 2018 was estimated using the Black-Scholes option pricing model that uses the assumptions noted in the following table to produce a Monte Carlo simulation. The fair value of share options granted was estimated using the following assumptions: June 30, 2019 2018 Expected dividend yield (%) (1) N/A 3.7 % Expected share price volatility (%) (2) N/A 21.0 % Risk-free interest rate (%) (3) N/A 2.1 % Expected life of options (in years) (4) N/A 4.0 (1) Determined assuming no change in dividend payout during the expected term of the option. (2) Determined based on the observed historical volatility for the Company's ordinary share price. (3) Determined based on the yields on Australian Government Bonds in effect at the time of grant with maturities approximately equal to the share options' expected term. (4) Determined considering the options' contractual terms, historical exercise and post-vesting termination patterns. The Company reassesses the probability of vesting at each reporting period and adjusts compensation expense based on its probability assessment. Changes in outstanding share options for the year were as follows: Share Options Weighted-average Exercise Price Weighted-average Contractual Life (in millions) (in years) Share options outstanding at June 30, 2018 14.4 $ 10.2 5.9 Granted — N/A N/A Exercised (2.5 ) 7.0 2.2 Forfeited (1.1 ) 10.7 3.8 Share options outstanding at June 30, 2019 10.8 10.3 3.6 Vested and exercisable at June 30, 2019 1.5 $ 6.9 2.1 The aggregate intrinsic value (difference in exercise price and closing price at that date) for all share options outstanding at June 30, 2019 was $12.6 million . The aggregate intrinsic value for share options vested and exercisable at June 30, 2019 was $6.8 million . The Company received $19.3 million , $28.1 million and $23.8 million and realized a tax benefit of $5.5 million , $12.3 million and $22.8 million on the exercise of stock options during the years ended June 30, 2019, 2018 and 2017, respectively. During the years ended June 30, 2019, 2018 and 2017, the intrinsic value associated with the exercise of share options was $8.3 million , $20.6 million and $37.0 million , respectively. The weighted average grant date fair value of share options granted and the fair value of share options vested was as follows: Years ended June 30, 2019 2018 2017 Weighted average grant date fair value of share options granted N/A $ 1.1 $ 1.2 Fair value of share options vested (in millions) $ 3.8 $ 5.3 $ 3.8 Restricted Shares Restricted shares/ units may be granted to directors, officers and employees of the Company and vest on terms as described in the award. The restrictions prevent the participant from disposing of the restricted shares/ units during the vesting period. The fair value of restricted shares/units is determined based on the closing price of the Company's shares on the grant date. Changes in the restricted shares/units for the year were as follows: Restricted Shares/Units Weighted-average Grant Date Fair Value (in millions) Nonvested restricted shares/units at June 30, 2018 0.6 $ 11.5 Granted — N/A Vested — N/A Forfeited (0.1 ) 11.7 Nonvested restricted shares/units at June 30, 2019 0.5 $ 11.4 The weighted average grant date fair value of restricted shares granted and the fair value of restricted shares vested was as follows: Years ended June 30, 2019 2018 2017 Weighted average grant date fair value of restricted shares granted N/A $ 11.5 $ 11.6 Fair value of restricted shares/units vested (in millions) $ 0.2 $ 1.8 $ 1.3 Performance Rights and Performance Shares There were no performance rights or performance shares (awarded to U.S. participants in place of performance rights) granted in fiscal year 2019 as they were deferred due to the transaction with Bemis. In fiscal year 2018, performance rights or performance shares were granted to officers and employees. The requisite service period for outstanding performance rights or performance shares in fiscal year 2019 ranges from three to four years. The awards are also subject to performance and market conditions. At vesting, performance rights can be exercised and converted to ordinary shares on a one-for-one basis. Performance shares vest automatically and convert to ordinary shares on a one-for-one basis. There is no amount payable by the participant. The fair value of the performance rights and performance shares granted in fiscal year 2018 was estimated using the Black-Scholes option pricing model that uses the assumptions noted in the following table to produce a Monte Carlo simulation. The fair value of the performance rights and performance shares was estimated using the following assumptions: June 30, 2019 2018 Expected dividend yield (%) (1) N/A 3.7 % Expected share price volatility (%) (2) N/A 21.0 % Risk-free interest rate (%) (3) N/A 2.1 % (1) Determined assuming no change in dividend payout during the expected term of the performance rights/performance shares. (2) Determined based on the observed historical volatility for the Company's ordinary share price. (3) Determined based on the yields on Australian Government Bonds in effect at the time of grant with maturities approximately equal to the performance rights/performance shares expected term. Performance Rights/Performance Shares Weighted-Average Grant Date Fair Value (in millions) Nonvested performance rights/performance shares at June 30, 2018 2.8 $ 6.2 Granted — N/A Exercised — N/A Forfeited (1.1 ) 5.6 Nonvested performance rights/performance shares at June 30, 2019 1.7 $ 6.3 The weighted average grant date fair value of performance rights and performance shares granted and the fair value of performance rights/ performance shares’ vested was as follows: Years ended June 30, 2019 2018 2017 Weighted average grant date fair value of performance rights/performance shares granted N/A $ 6.3 $ 7.1 Fair value of performance rights/performance shares vested (in millions) $ 0.1 $ 0.8 $ 3.2 Share Rights Share rights may be granted to directors, officers and employees of the Company and vest on terms as described in the award. The restrictions prevent the participant from disposing of the share rights during the vesting period. The fair value of share rights is determined based on the closing price of the Company's shares on the grant date, adjusted for dividend yield. Changes in the share rights for the year were as follows: Share Rights Weighted-Average Grant Date Fair Value (in millions) Nonvested share rights at June 30, 2018 2.5 $ 10.7 Granted 0.6 9.2 Exercised (1.4 ) 10.1 Forfeited (0.2 ) 10.4 Nonvested share rights at June 30, 2019 1.5 $ 10.0 The weighted average grant date fair value of share rights granted and the fair value of shares vested was as follows: Years ended June 30, 2019 2018 2017 Weighted average grant date fair value of share rights granted $ 9.2 $ 11.0 $ 10.9 Fair value of share rights vested (in millions) $ 13.9 $ 12.9 $ 16.0 Compensation Expense Share-based compensation expense of $18.6 million , $21.0 million and $26.5 million was primarily recorded in general and administrative expenses for fiscal years 2019, 2018 and 2017 , respectively. Compensation expense for share-based awards recognized in the consolidated income statements, net of estimated forfeitures, was as follows: Years ended June 30, (in millions) 2019 2018 2017 Share options $ 2.8 $ 3.0 $ 4.8 Restricted shares 1.6 2.8 0.9 Performance shares/rights 3.0 2.9 4.3 Share rights 8.5 9.7 16.4 Cash-settled awards 2.7 2.6 — Other — — 0.1 Total share-based compensation expense $ 18.6 $ 21.0 $ 26.5 As of June 30, 2019 , there was $16.9 million of total unrecognized compensation cost related to all unvested share options, restricted shares/units, performance shares/performance rights and share rights. That cost is expected to be recognized over a weighted average period of 1.6 years.

Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	Earnings Per Share Computations The Company applies the two-class method when computing its earnings per share ("EPS"), which requires that net income per share for each class of share be calculated assuming 100% of the Company's net income is distributed as dividends to each class of share based on their contractual rights. Basic EPS is computed by dividing net income available to ordinary shareholders by the weighted-average number of ordinary shares outstanding after excluding the ordinary shares to be repurchased using forward contracts. Diluted EPS includes the effects of share options, restricted shares, performance rights, performance shares and share rights, if dilutive. Years ended June 30, (in millions, except per share amounts) 2019 2018 2017 Numerator Net income attributable to Amcor plc $ 430.2 $ 575.2 $ 564.0 Distributed and undistributed earnings attributable to shares to be repurchased (0.8 ) (1.3 ) (1.7 ) Net income available to ordinary shareholders of Amcor plc—basic and diluted $ 429.4 $ 573.9 $ 562.3 Net income available to ordinary shareholders of Amcor plc from discontinued operations—basic and diluted $ 0.7 $ — $ — Net income available to ordinary shareholders of Amcor plc from continuing operations—basic and diluted $ 428.7 $ 573.9 $ 562.3 Denominator Weighted-average ordinary shares outstanding 1,182.6 1,157.1 1,157.2 Weighted-average ordinary shares to be repurchased by Amcor plc (2.3 ) (2.7 ) (3.5 ) Weighted-average ordinary shares outstanding for EPS—basic 1,180.3 1,154.4 1,153.7 Effect of dilutive shares 3.5 7.3 10.5 Weighted-average ordinary shares outstanding for EPS—diluted 1,183.8 1,161.7 1,164.2 Per ordinary share income Income from continuing operations $ 0.36 $ 0.50 $ 0.49 Income from discontinued operations $ — $ — $ — Basic earnings per ordinary share $ 0.36 $ 0.50 $ 0.49 Income from continuing operations $ 0.36 $ 0.49 $ 0.48 Income from discontinued operations $ — $ — $ — Diluted earnings per ordinary share $ 0.36 $ 0.49 $ 0.48 Certain stock awards outstanding were not included in the computation of diluted earnings per share above because they would not have had a dilutive effect.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Contingencies and Legal Proceedings Contingencies The Company's operations in Brazil are involved in various governmental assessments, principally related to claims for excise and income taxes. The Company does not believe that the ultimate resolution of these matters will materially impact the Company's consolidated results of operations, financial position or cash flows. Under customary local regulations, the Company's Brazilian subsidiaries may need to post cash or other collateral if a challenge to any administrative assessment proceeds to the Brazilian court system; however, the level of cash or collateral already pledged or potentially required to be pledged would not significantly impact the liquidity of Amcor. At June 30, 2019 and 2018 , the Company has recorded an accrual of $16.4 million and $15.1 million , respectively, included in other non-current liabilities in the consolidated balance sheet and has estimated a reasonably possible loss exposure in excess of the accrual of $23.7 million and $22.7 million , respectively. The litigation process is subject to many uncertainties and the outcome of individual matters cannot be accurately predicted. The Company's assessments are based on its knowledge and experience, but the ultimate outcome of any of these matters may differ from the Company's estimates. As of June 30, 2019 , Amcor provided letters of credit of $45.4 million and deposited cash of $14.0 million with the courts to continue to defend the cases. Legal Proceedings On April 18, 2019, prior to the closure of the Amcor and Bemis transaction, litigation funding firm, Burford Capital, notified Bemis on behalf of two shareholder funds (BCIM Strategic Value Master Fund LP and BCIM SV SMA I LLC) that the funds would not accept the fixed exchange ratio for Amcor shares and instead intended to file a case asking a Missouri state court to appraise the value of their Bemis shares and compensate them accordingly. On June 24, 2019, the Burford funds sent a formal written demand for payment of the fair value of the funds’ shares. The Burford funds can file a lawsuit in Missouri state court between now and September 9, 2019. As no lawsuit has been filed as of the date of this update, it is not possible to predict the potential exposure. Three lawsuits brought by purported holders of Bemis stock against Bemis and Bemis directors and officers are pending in federal court in the U.S. District Court for the Southern District of New York, in which plaintiffs are seeking damages for alleged violations of the Exchange Act of 1934 and U.S. Securities and Exchange Commission rules and regulations. Plaintiffs allege a failure to disclose adequately information in the proxy statement issued in connection with the Amcor-Bemis merger. The cases are: Dixon, et al. v. Bemis Company, Inc. et al. ; Nolan, et al. v. Bemis Company, Inc. et al. ; and, Stein v. Bemis Company, Inc. et al ., which were instituted on April 15, 2019, April 19, 2019, and April 17, 2019, respectively. In addition, a purported holder of Bemis stock filed a putative derivative suit in the Cole County Circuit Court, Nineteenth Judicial District of Missouri, against Bemis directors and Amcor, alleging that the directors breached fiduciary duties in connection with the Amcor-Bemis merger and that Amcor aided and abetted breaches of fiduciary duty. The case is Scarantino, et al. v. Amcor Limited, et al. , which was instituted on April 19, 2019. Amcor intends to defend the claims made in the pending actions. It is too early for Amcor to provide any reliable assessment of the likely quantum of any damages that may become payable if its defense is unsuccessful in whole or in part. Although it is not possible at present to establish a reliable assessment of damages, there can be no assurance that any damages that may be awarded will not be material to the results of operations or financial condition of Amcor.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	Segments The Company's business is organized and presented in the two reportable segments outlined below: Flexibles: Consists of operations that manufacture flexible and film packaging in the food and beverage, medical and pharmaceutical, fresh produce, snack food, personal care, and other industries. Rigid Packaging: Consists of operations that manufacture rigid plastic containers for a broad range of predominantly beverage and food products, including carbonated soft drinks, water, juices, sports drinks, milk-based beverages, spirits and beer, sauces, dressings, spreads and personal care items and plastic caps for a wide variety of applications. Other consists of the Company's equity method investments, including AMVIG, undistributed corporate expenses, intercompany eliminations and other business activities. Operating segments are organized along the Company's product lines and geographical areas and consist of the following: Flexibles Europe, Middle East and Africa; Flexibles Americas; Flexibles Asia Pacific and Specialty Cartons, and Rigid Packaging. The four Flexibles operating segments (Flexibles Europe, Middle East and Africa; Flexibles Americas; Flexibles Asia Pacific and Specialty Cartons) have been aggregated in the Flexibles reporting segment as they exhibit similar economic characteristics as they are in the business of printing and flexible packaging of fast moving consumer products. In the fourth quarter of fiscal year 2019, in connection with the acquisition of Bemis, the Company changed its measure of segment performance from adjusted operating income to adjusted earnings before interest and tax ("EBIT") from continuing operations. The Company's chief operating decision maker, the Global Management Team ("GMT"), evaluates performance and allocates resources based on adjusted EBIT from continuing operations. The Company defines adjusted EBIT as operating income adjusted to eliminate the impact of certain items that the Company does not consider indicative of its ongoing operating performance and to include equity in income (loss) of affiliated companies. The GMT consists of the Managing Director and Chief Executive Officer and his direct reports and provides strategic direction and management oversight of the day to day activities of the Company. The accounting policies of the reportable segments are the same as those in the consolidated financial statements and are discussed in Note 2 , " Significant Accounting Policies ." The Company also has investments in operations in AMVIG that are accounted for under the equity method of accounting and, accordingly, those results are not included in segment net sales.

Amcor Limited (former parent entity of the Amcor Group) is ineligible to rely on ASIC Corporations (Wholly-owned Companies) Instrument 2016/785 for fiscal year 2019 as a wholly-owned entity of Amcor plc because it was a disclosing entity for part of the relevant fiscal year. However, the Australian Securities and Investments Commission ("ASIC") has provided Amcor Limited with separate relief under ASIC Instrument 19-0555. Under this Instrument ASIC has ordered that Amcor Limited does not have to comply with a number of Australian reporting requirements including the requirement to prepare and file a stand-alone financial report in Australia. The financial statements below are additional disclosure items specifically required by ASIC and represent the consolidated results of the entities subject to the Deed only.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended
	Jun. 30, 2019
Accounting Policies [Abstract]
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant and Equipment, Net: Property, plant and equipment ("PP&E"), net is carried at cost less accumulated depreciation and impairment and includes expenditures for new facilities and equipment and those costs which substantially increase the useful lives or capacity of existing PP&E. Cost of constructed assets includes capitalized interest incurred during the construction period. Maintenance and repairs that do not improve efficiency or extend economic life are expensed as incurred. PP&E is depreciated using the straight-line method over the estimated useful lives of assets or, in the case of leasehold improvements and leased assets, over the period of the lease or useful life of the asset, whichever is shorter, as described below. The Company periodically reviews these estimated useful lives and, when appropriate, changes are made prospectively. Leasehold land Over lease term Land improvements Shorter of lease term or 20 - 33 years Buildings 14 - 40 years Plant and equipment 3 - 25 years Capital leases Shorter of lease term or 5 - 25 years For tax purposes, the Company generally uses accelerated methods of depreciation. The tax effect of the difference between book and tax depreciation has been provided for as deferred income taxes.
Inventory, Policy [Policy Text Block]	Inventories: Inventories are valued at the lower of cost, as determined by the first-in, first-out ("FIFO") method, or net realizable value. Inventory values using the FIFO method of accounting approximate replacement cost. Inventories are summarized at June 30, as follows: (in millions) 2019 2018 Raw materials and supplies $ 864.6 $ 640.8 Work in process 348.9 200.9 Finished goods 832.0 573.0 Less: inventory reserves (91.7 ) (55.9 ) Total inventories (1) $ 1,953.8 $ 1,358.8 (1) Increase primarily attributable to the acquisition of Bemis Company. Refer to Note 4, "Acquisitions," for more information about the Company's acquisition of Bemis.
Discontinued Operations, Policy [Policy Text Block]	Discontinued Operations Presentation: The consolidated financial statements and related notes reflect the three plants in Europe acquired as part of the Bemis acquisition as a discontinued operation (see Note 5 , " Discontinued Operations ") as the Company agreed to divest of these plants as a condition of approval from the European Commission.
Consolidation, Policy [Policy Text Block]	Basis of Presentation and Principles of Consolidation: The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All intercompany transactions and balances have been eliminated. The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP").
Business Combinations Policy [Policy Text Block]	Business Combinations: The Company uses the acquisition method of accounting, which requires separate recognition of assets acquired and liabilities assumed from goodwill, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the fair value of any non-controlling interests in the acquiree over the net of the acquisition date fair values of the assets acquired and liabilities assumed. During the measurement period, which may be up to one year from the acquisition date, the Company has the ability to record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded in the consolidated income statement.
Use of Estimates, Policy [Policy Text Block]	Estimates and Assumptions Required: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. These estimates are based on historical experience and various assumptions believed to be reasonable under the circumstances. Management evaluates these estimates on an ongoing basis and adjusts or revises the estimates as circumstances change. As future events and their impacts cannot be determined with precision, actual results may differ from these estimates. In the opinion of management, the consolidated financial statements reflect all adjustments necessary to fairly present the results of the periods presented.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Translation of Foreign Currencies: The reporting currency of the Company is the U.S. dollar. The functional currency of the Company’s subsidiaries is generally the local currency of such entity. Transactions in currencies other than the functional currency of the entity are recorded at the rates of exchange prevailing at the date of the transaction. Monetary assets and liabilities in currencies other than the entity’s functional currency are remeasured at the exchange rate as of the balance sheet date to the entity’s functional currency. Foreign currency transaction gains and losses related to short-term and long-term debt are recorded in other non-operating income (loss), net in the consolidated income statements. The Company recorded such foreign currency transaction net gains (losses) of $1.1 million , $(82.7) million and $40.7 million during the years ended June 30, 2019, 2018 and 2017, respectively. All other foreign currency transaction gains and losses are recorded in other income, net in the consolidated income statements. These foreign currency transaction net gains (losses) amounted to $8.9 million , $1.0 million and $1.0 million during the years ended June 30, 2019, 2018 and 2017, respectively. Upon consolidation, the results of operations of subsidiaries whose functional currency is other than the reporting currency of the Company are translated using average exchange rates in effect during each year. Assets and liabilities of operations with a functional currency other than the U.S. dollar are translated at the exchange rate as of the balance sheet date, while equity balances are translated at historical rates. Translation gains and losses are reported in accumulated other comprehensive income (loss) as a component of shareholders’ equity.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition: The Company generates revenue by providing its customers with flexible and rigid packaging serving a variety of markets including food, consumer products and healthcare end markets. The Company enters into a variety of agreements with customers, including quality agreements, pricing agreements and master supply agreements which outline the terms under which the Company does business with a specific customer. The Company also sells to some customers solely based on purchase orders. The Company has concluded for the vast majority of its revenues, that its contracts with customers are either a purchase order or the combination of a purchase order with a master supply agreement. All revenue recognized in the income statement is considered to be revenue from contracts with customers. The Company typically satisfies the obligation to provide packaging to customers at a point in time upon shipment when control is transferred to customers. Revenue is recognized net of allowances for returns and customer claims and any taxes collected from customers, which are subsequently remitted to governmental authorities. The Company does not have any material contract assets or contract liabilities. The Company disaggregates revenue based on geography. Disaggregation of revenue is presented in Note 20 , " Segments ". Significant Judgments Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. The Company identified potential performance obligations in its customer master supply agreements and determined that none of them are capable of being distinct as the customer can only benefit from the supplied packaging. Therefore, the Company has concluded that it has one performance obligation to supply packaging to customers. The Company may provide variable consideration in several forms which are determined through its agreements with customers. The Company can offer prompt payment discounts, sales rebates or other incentive payments to customers. Sales rebates and other incentive payments are typically awarded upon achievement of certain performance metrics, including volume. The Company accounts for variable consideration using the most likely amount method. The Company utilizes forecasted sales data and rebate percentages specific to each customer agreement and updates its judgment of the amounts to which the customer is entitled each period. The Company enters into long term agreements with certain customers, under which it is obligated to make various up-front payments for which it expects to receive a benefit in excess of the cost over the term of the contract. These up-front payments are deferred and reflected in prepaid expenses and other current assets or other non-current assets on its consolidated balance sheet. Contract incentives are typically recognized as a reduction to revenue over the term of the customer agreement. Practical Expedients The Company sells primarily through its direct sales force. Any external sales commissions are expensed when incurred because the amortization period would be one year or less. External sales commission expense is included in selling, general and administrative expense in the consolidated statement of income. The Company accounts for shipping and handling activities as fulfillment costs. Accordingly, shipping and handling costs are classified as a component of cost of products sold while amounts billed to customers are classified as a component of net sales. The Company excluded from the measurement of the transaction price all taxes assessed by a government authority that are both imposed on and concurrent with a specific revenue producing transaction and collected from the customer, including sales taxes, value added taxes, excise taxes and use taxes. Accordingly, the tax amounts are not included in net sales. The Company will not adjust the promised consideration for the time value of money for contracts where the difference between the time of payment and performance is one year or less.
Research and Development Expense, Policy [Policy Text Block]	Research and Development: Research and development expenditures are expensed as incurred.
Costs Associated with Exit or Disposal Activities or Restructurings, Policy [Policy Text Block]	Restructuring Costs: Restructuring costs are recognized when the liability is incurred. The Company calculates severance obligations based on its standard customary practices. Accordingly, the Company records provisions for severance when probable and estimable and the Company has committed to the restructuring plan. In the absence of a standard customary practice or established local practice, liabilities for severance are recognized when incurred. If fixed assets are to be disposed of as a result of the Company’s restructuring efforts, the assets are written off when the Company commits to dispose of them and they are no longer in use. Depreciation is accelerated on fixed assets for the period of time the asset continues to be used until the asset ceases to be used. Other restructuring costs, including costs to relocate equipment, are generally recorded as the cost is incurred or the service is provided.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents: The Company considers all highly liquid temporary investments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents include certificates of deposit that can be readily liquidated without penalty at the Company’s option. Cash equivalents are carried at cost which approximates fair market value.
Trade and Other Accounts Receivable, Policy [Policy Text Block]	Trade Receivables, Net: Trade accounts receivable, net, are stated at the amount the Company expects to collect, which is net of an allowance for sales returns and the estimated losses resulting from the inability of its customers to make required payments. When determining the collectability of specific customer accounts, a number of factors are evaluated, including: customer creditworthiness, past transaction history with the customer and changes in customer payment terms or practices. In addition, overall historical collection experience, current economic industry trends and a review of the current status of trade accounts receivable are considered when determining the required allowance for doubtful accounts. The Company has an allowance for doubtful accounts of $34.4 million and $16.9 million recorded at June 30, 2019 and 2018 , respectively, in trade receivables, net, on the consolidated balance sheet. The current year expense to adjust the allowance for doubtful accounts is recorded within selling, general and administrative expenses in the consolidated statement of income. The Company enters into factoring arrangements from time to time to sell trade receivables to third-party financial institutions. Sales of receivables are accounted for in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 860, Transfers and Servicing ("ASC 860"). Agreements which result in true sales of the transferred receivables, as defined in ASC 860, which occur when receivables are transferred without recourse to the Company, are reflected as a reduction of trade receivables, net on the consolidated balance sheets and the proceeds are included in the cash flows from operating activities in the consolidated statements of cash flows. Agreements that allow the Company to maintain effective control over the transferred receivables and which do not qualify as a true sale, as defined in ASC 860, are accounted for as secured borrowings and recorded in the consolidated balance sheets within trade receivables, net and short-term debt. The expenses associated with receivables factoring are recorded in the consolidated income statements within interest expense. As of June 30, 2019 , $24.7 million of trade receivables were factored qualifying as a true sale and the associated discount on sale was not significant. Factored receivables not qualifying as a true sale were accounted for as secured borrowings. As of June 30, 2018, none of the factoring arrangements the Company entered into qualified as true sales and thus were accounted for as secured borrowings. As of June 30, 2019 and 2018 , amounts factored recorded under trade receivables, net and short-term debt, were $152.7 million and $335.6 million , respectively.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-lived Assets: The Company reviews long-lived assets, primarily PP&E and certain identifiable intangible assets with finite lives, for impairment when facts or circumstances indicate the carrying amount of an asset or asset group may not be recoverable. If impairment indicators are present and the estimated future undiscounted cash flows are less than the carrying value of the assets, the carrying values are reduced to the estimated fair value. Fair values are determined based on quoted market values, discounted cash flows or external appraisals, as applicable. Impairment losses recognized in the consolidated income statement were as follows: Years ended June 30, (in millions) 2019 2018 2017 Selling, general and administrative expenses (SG&A) $ 47.7 $ 0.4 $ — Restructuring related costs 27.4 4.0 22.4 Total impairment losses recognized in the consolidated income statements $ 75.1 $ 4.4 $ 22.4
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill: Goodwill represents the excess of cost over the fair value of net assets acquired in a business combination. Goodwill is not amortized, but instead tested annually or whenever events and circumstances indicate an impairment may have occurred during the year. Among the factors that could trigger an impairment review are a reporting unit’s operating results significantly declining relative to its operating plan or historical performance, and competitive pressures and changes in the general markets in which it operates. All goodwill is assigned to a reporting unit, which is defined as the operating segment, or one level below the operating segment. The Company has 5 reporting units with goodwill that are assessed for potential impairment. In performing the required impairment tests, the Company has the option to first assess qualitative factors to determine if it is necessary to perform a quantitative assessment for goodwill impairment. If the qualitative assessment concludes that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value, a quantitative assessment is performed. A quantitative assessment primarily consists of a present value (discounted cash flow) method to determine the fair value of the reporting units with goodwill. The Company performs its annual impairment analysis in the fourth quarter of each year. A qualitative impairment analysis was performed on all reporting units for the fiscal year ended 2019, while a quantitative analysis was performed for fiscal years ended 2018 and 2017. The analysis concluded that goodwill was not impaired.
Intangible Assets, Finite-Lived, Policy [Policy Text Block]	Other Intangible Assets, Net: Contractual or separable intangible assets that have finite useful lives are amortized against income using the straight-line method over their estimated useful lives, with original periods ranging from one to 20 years. The straight-line method of amortization reflects an appropriate allocation of the costs of the intangible assets to earnings in proportion to the amount of economic benefits obtained by the Company in each reporting period. The Company tests finite-lived intangible assets for impairment when facts and circumstances indicate carrying value may not be recoverable from their undiscounted cash flows. If impaired, the assets are written down to fair value based on either discounted cash flows or appraised values. Costs incurred to develop software programs to be used solely to meet the Company's internal needs have been capitalized as computer software within other intangible assets.
Derivatives, Policy [Policy Text Block]	Financial Instruments: The Company recognizes all derivative instruments on the balance sheet at fair value. The impact on earnings from recognizing the fair values of these instruments depends on their intended use, their hedge designation and their effectiveness in offsetting changes in the fair values of the exposures they are hedging. Derivatives not designated as hedging instruments are adjusted to fair value through income. Depending on the nature of derivatives designated as hedging instruments, changes in the fair value are either offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings or recognized in shareholders’ equity through other comprehensive income until the hedged item is recognized. Gains or losses, if any, related to the ineffective portion of any hedge are recognized through earnings in the current period. Note 11 , " Derivative Instruments ," contains expanded details relating to specific derivative instruments included on the Company’s balance sheet, such as forward foreign currency exchange contracts, currency swap contracts, and interest rate swap arrangements.
Pension and Other Postretirement Plans, Policy [Policy Text Block]	Employee Benefit Plans: The Company sponsors various defined contribution plans to which it makes contributions on behalf of employees. The expense under such plans was $39.9 million , $39.8 million and $39.9 million for the years ended June 30, 2019 , 2018 and 2017 , respectively. The Company sponsors a number of defined benefit plans that provide benefits to current and former employees. For the company-sponsored plans, the relevant accounting guidance requires that management make certain assumptions relating to the long-term rate of return on plan assets, discount rates used to determine the present value of future obligations and expenses, salary inflation rates, mortality rates and other assumptions. The Company believes that the accounting estimates related to its pension plans are critical accounting estimates because they are highly susceptible to change from period to period based on the performance of plan assets, actuarial valuations, market conditions and contracted benefit changes. The selection of assumptions is based on historical trends and known economic and market conditions at the time of valuation, as well as independent studies of trends performed by the Company’s actuaries. However, actual results may differ substantially from the estimates that were based on the critical assumptions. The Company recognizes the funded status of each defined benefit pension plan in the consolidated balance sheet. Each overfunded plan is recognized as an asset and each underfunded plan is recognized as a liability. Pension plan liabilities are revalued annually, or when an event occurs that requires remeasurement, based on updated assumptions and information about the individuals covered by the plan. Accumulated actuarial gains and losses in excess of a 10 percent corridor and the prior service cost are amortized on a straight-line basis from the date recognized over the average remaining service period of active participants or over the average life expectancy for plans with significant inactive participants. The service costs related to defined benefits are included in operating income. The other components of net benefit cost are presented in the consolidated income statements separately from the service cost component and outside operating income.
Equity Method Investments [Policy Text Block]	Equity Method Investments: Investments in ordinary shares of companies, in which the Company believes it exercises significant influence over operating and financial policies, are accounted for using the equity method of accounting. Under this method, the investment is carried at cost and is adjusted to recognize the investor’s share of earnings or losses of the investee after the date of acquisition and is adjusted for impairment whenever it is determined that a decline in the fair value below the cost basis is other than temporary. See Note 7 , " Equity Method Investments ," for more information regarding the Company's equity method investments.
Share-based Compensation, Forfeitures [Policy Text Block]	Share-Based Compensation: Amcor has a variety of equity incentive plans. For employee awards with a service or market condition, compensation expense is recognized over the vesting period on a straight-line basis using the grant date fair value of the award and the estimated number of awards that are expected to vest. For awards with a performance condition, the Company must reassess the probability of vesting at each reporting period and adjust compensation cost based on its probability assessment. The Company also has cash-settled share-based compensation plans which are accounted for as liabilities. Such share-based awards are remeasured to fair value at each reporting period. The Company estimates forfeitures based on employee level, economic conditions, time remaining to vest and historical forfeiture experience.
Income Tax, Policy [Policy Text Block]	Income Taxes: The Company uses the asset and liability method to account for income taxes. Deferred income taxes reflect the future tax consequences of differences between the tax bases of assets and liabilities and their financial reporting amounts at each balance sheet date, based upon enacted income tax laws and tax rates. Income tax expense or benefit is provided based on earnings reported in the financial statements. The provision for income tax expense or benefit differs from the amounts of income taxes currently payable because certain items of income and expense included in the consolidated financial statements are recognized in different time periods by taxing authorities. Deferred tax assets, including operating loss, capital loss and tax credit carryforwards, are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that any portion of these tax attributes will not be realized. In addition, from time to time, management must assess the need to accrue or disclose uncertain tax positions for proposed adjustments from various tax authorities who regularly audit the Company in the normal course of business. In making these assessments, management must often analyze complex tax laws of multiple jurisdictions. Accounting guidance prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company records the related interest expense and penalties, if any, as tax expense in the tax provision. See Note 16 , " Income Taxes ," for more information.
