Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	BUSINESS DESCRIPTION Bemis Company, Inc. (the "Company"), a Missouri corporation based in Neenah, Wisconsin, was founded in 1858 and incorporated in 1885 as Bemis Bro. Bag Company. In 1965 the name was changed to Bemis Company, Inc. At December 31, 2018, the Company employed approximately 15,700 individuals and had 54 manufacturing facilities. The Company manufactures and sells packaging products globally. The Company’s business activities are organized around its three business segments, U.S. Packaging, Latin America Packaging, and Rest of World Packaging. The Company’s packaging businesses have a strong technical base in polymer chemistry, film extrusion, coating, laminating, printing, and converting. The Company’s products are primarily sold in the food industry, which accounted for approximately 80 percent of net sales in 2018 . The Company’s packaging products are widely diversified among food categories and can be found in nearly every aisle of the grocery store. Other markets include chemical, agribusiness, medical, pharmaceutical, personal care products, electronics, industrial, and other consumer goods. All markets are considered to be highly competitive as to price, innovation, quality, and service. Definitive Transaction Agreement with Amcor On August 6, 2018, the Company announced that its Board of Directors, along with the Board of Directors of Amcor Limited (“Amcor”), unanimously approved a definitive agreement (the "Agreement”) under which Bemis will combine with Amcor in an all-stock combination (“the Transaction”). The Transaction will be effected at a fixed exchange ratio of 5.1 Amcor shares for each share of the Company, resulting in Amcor and Bemis shareholders owning approximately 71 % and 29 % of the combined company, respectively. Closing of the Transaction is conditional upon the receipt of regulatory approvals, approval by both Amcor and Bemis shareholders, and satisfaction of other customary conditions. Subject to the satisfaction of the conditions to closing, the Transaction is targeted to close in the second quarter of calendar year 2019. The Agreement contains certain termination rights for both Bemis and Amcor, including if the Transaction is not completed on or before August 6, 2019, subject in certain circumstances to extension to February 6, 2020 if necessary to secure certain regulatory approvals. The Agreement provides that Bemis will pay a $ 130 million termination fee to Amcor if, among other things, Bemis terminates the Agreement to enter into a superior proposal or if the Agreement is terminated following Bemis’s Board of Directors changing its recommendation or failing to publicly affirm the board recommendation after receipt of a competing proposal. The Agreement also provides that Amcor will pay a $ 130 million termination fee to Bemis under similar circumstances. During 2018, in connection with the Transaction, the Company incurred pre-tax expenses of $ 14.3 million related to professional fees which are recorded in Restructuring and other costs in the condensed consolidated statement of income.

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	SIGNIFICANT ACCOUNTING POLICIES Principles of consolidation: The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All intercompany transactions and accounts have been eliminated. Joint ventures which are not majority controlled are accounted for by the equity method of accounting with earnings of $ 2.3 million , $ 2.9 million , and $ 2.2 million in 2018 , 2017 , and 2016 , respectively, included in other operating income on the accompanying consolidated statement of income. Investments in joint ventures of $ 6.9 million and $ 8.9 million as of December 31, 2018 and 2017 , respectively, are included in deferred charges and other assets on the accompanying consolidated balance sheet. Estimates and assumptions required: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Translation of foreign currencies: The Company considers the local currency to be the functional currency for substantially all foreign subsidiaries. Assets and liabilities are translated at the exchange rate as of the balance sheet date. All revenue and expense accounts are translated at average exchange rates in effect during the year. Translation gains or losses are recorded in the foreign currency translation component in accumulated other comprehensive loss in shareholders’ equity. Foreign currency transaction losses of $ 0.3 million and $ 0.6 million in 2018 and 2017, respectively, and gains of $ 0.4 million in 2016 , are included as a component of other operating income. Foreign currency transaction losses of $ 0.7 million were recorded within non-operating income in 2016. There were no foreign currency transaction losses recorded within non-operating income in 2018 or 2017. During the third quarter of 2018, we began accounting for our operations in Argentina as highly inflationary, as the country’s three-year cumulative inflation rate exceeded 100%. As a result, the functional currency of our Argentine subsidiary became the U.S. dollar. Revenue recognition: The Company generates revenue by providing its customers with flexible and rigid plastic 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 contract assets or contract liabilities. The Company disaggregates revenue based on geography. Disaggregation of revenue is presented in Note 19 - Segments of Business. 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 deferred charges and other 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 on its 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 for locations outside the U.S., 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: Trade accounts receivable 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. Based on management’s assessment, the Company provides for estimated uncollectible amounts through a charge to earnings and a credit to allowance for doubtful accounts. Balances that remain outstanding after the Company has used reasonable collection efforts are written off through a charge to the allowance for doubtful accounts and a credit to trade receivables. Trade receivables are presented net of an allowance for doubtful accounts of $ 16.4 million and $ 17.7 million at December 31, 2018 and 2017 , respectively. The Company enters into supply chain financing programs from time to time to sell trade receivables without recourse to third-party financial institutions. Sales of trade receivables are reflected as a reduction of trade receivables on the consolidated balance sheets and the proceeds are included in the cash flows from operating activities in the consolidated statements of cash flows. During both the years ended December 31, 2018 and 2017, the Company sold without recourse trade receivables representing approximately 20 percent of net sales, and the associated discount on sale of trade receivables was not significant. Inventory valuation: 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 December 31, as follows: (in millions) 2018 2017 Raw materials and supplies $ 197.4 $ 198.3 Work in process and finished goods 422.1 421.9 Total inventories $ 619.5 $ 620.2 Property and equipment: Property and equipment are stated at cost. Maintenance and repairs that do not improve efficiency or extend economic life are expensed as incurred. Plant and equipment are depreciated for financial reporting purposes principally using the straight-line method over the estimated useful lives of assets as follows: land improvements, 15 - 30 years; buildings, 15 - 45 years; leasehold and building improvements, the lesser of the lease term or 8 - 20 years; and machinery and equipment, 3 - 17 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 as deferred income taxes. Depreciation expense was $ 150.7 million , $ 152.8 million , and $ 146.1 million for 2018 , 2017 , and 2016 , respectively. On sale or retirement, the asset cost and related accumulated depreciation are removed from the accounts and any related gain or loss is reflected in other operating income. The Company reviews its long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of the assets 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. The Company capitalizes direct costs (internal and external) of materials and services used in the development and purchase of internal-use software. Amounts capitalized are amortized on a straight-line basis over a period of three to twelve years and are reported as a component of machinery and equipment within property and equipment. The Company is in the process of developing and implementing a new Enterprise Resource Planning ("ERP") system. Certain costs incurred during the application development stage have been capitalized in accordance with authoritative accounting guidance related to accounting for costs of computer software developed or obtained for internal use. The net book value of capitalized costs for this new ERP system were approximately $ 47.6 million and $ 55.0 million as of December 31, 2018 and 2017 , respectively. These costs are being amortized over the system’s estimated useful life as the ERP system is placed in service. 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. 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. The Company has two reporting units with goodwill that is assessed for potential impairment. All goodwill is assigned to reporting units, which is defined as the operating segment, or one level below the operating segment. The Company has three reporting units, or operating segments, which align with the Company's reportable segment structure. Accounting guidance allows the Company to first perform a qualitative assessment about the likelihood of the carrying value of a reporting unit exceeding its fair value, referred to as the "Step 0" assessment. The Step 0 assessment requires the evaluation of certain qualitative factors, including macroeconomic conditions, industry and market considerations, cost factors and overall financial performance, as well as company and reporting unit factors. If the Company's Step 0 analysis indicates that it is more likely than not that the fair value of a reporting unit is less than the carrying amount, then the Company would perform a quantitative impairment test. The Company applied the Step 0 assessment to its two reporting units with goodwill in 2018 given the reporting units both had fair values significantly in excess of their carrying amounts when tested in 2017. The Company's Step 0 analysis in 2018 of the reporting units concluded that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount. Therefore, the quantitative goodwill impairment test for these reporting units was not necessary in 2018. In assessing goodwill for impairment the Company performed a two-step goodwill impairment test in 2016 and adopted the new accounting guidance for 2017, Accounting Standards Update 2017-04, Simplifying the Test for Goodwill Impairment , which allows for a single step method. Both approaches utilize two valuation approaches, the income approach and the market multiple approach. Under the income approach, the Company estimates the fair value of the reporting unit based on the present value of estimated future cash flows. Cash flow projections are based on management’s estimates of revenue growth rates and EBITDA margins, taking into consideration business and market conditions for the countries and markets in which the reporting unit operates. The Company calculates the discount rate based on a market-participant, risk-adjusted weighted average cost of capital, which considers industry specific rates of return on debt and equity capital for a target industry capital structure, adjusted for risks associated with business size and geography. Under the market multiples approach, the Company estimates fair value based on market multiples of EBITDA derived from publicly traded companies in the Company’s peer group, adjusted to reflect differences in size and growth prospects. During the second quarter of 2017, the Company initiated an interim impairment analysis of the Latin America Packaging reporting unit given the contraction in this reporting unit’s business late in the second quarter. This review did not result in any impairment of the reporting unit’s goodwill balance. As a result of further deterioration in the forecasted sales and profits of the Latin America Packaging reporting unit from the second quarter outlook and forecasted slow economic recovery, the Company determined in the fourth quarter of 2017 that the fair value of the reporting unit was less than its carrying value. In performing the analysis, the Company used discount rates and terminal growth rates of 11 percent and 3 percent , respectively, to calculate the present value of future cash flows. Accordingly, the Company recorded a noncash goodwill impairment charge of $ 196.6 million ($ 145.5 million after-tax) which is recorded in the goodwill impairment charge line of the consolidated income statement. The annual impairment test indicated the goodwill balances for the U.S. Packaging reporting unit and Rest of World Packaging reporting units were not impaired for the years ended December 31, 2018, 2017 or 2016 and the Company does not have any accumulated impairment losses for these reporting units. Intangible assets: 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 thirty 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 whenever there is an impairment indicator. The Company completed a test of the Latin America Packaging reporting unit intangibles in the fourth quarter of 2017 which concluded the assets were not impaired. Intangible assets are tested for impairment by comparing anticipated undiscounted future cash flows from operations to net book value. Financial instruments: The Company recognizes all derivative instruments on the balance sheet at fair value. 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 8 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. Other liabilities and deferred credits: Other liabilities and deferred credits balances include non-current pension and other postretirement liability amounts of $ 75.7 million and $ 47.6 million at December 31, 2018 and 2017 , respectively. Treasury stock: Treasury stock purchases are stated at cost and presented as a separate reduction of shareholders’ equity. During 2018, the Company did not purchase any common stock. During 2017, the Company purchased 2.2 million shares of common stock in the open market for $ 103.8 million . During 2016, the Company purchased 3.0 million shares of common stock in the open market for $ 143.9 million . At December 31, 2018 , approximately 18.2 million common shares can be repurchased, at management’s discretion, under authority granted by the Company’s Board of Directors. Certain prior period amounts have been reclassified to conform to the current period presentation.

New Accounting Guidance [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	NEW ACCOUNTING GUIDANCE Recently Adopted Accounting Standards In February 2018, the Financial Accounting Standards Board ("FASB") issued guidance on the reclassification of certain tax effects from accumulated other comprehensive income. The guidance 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 ("TCJA"), along with information about other income tax effects that are reclassified. The Company elected to early adopt this guidance during the fourth quarter of fiscal 2018. The Company had $ 20.2 million of net stranded income tax effects in accumulated other comprehensive income within the Consolidated Balance Sheets as a result of the lower U.S. federal corporate tax rate due to the enactment of the TCJA. The adoption of the guidance resulted in the transfer of $ 20.2 million of net stranded income tax effects out of accumulated other comprehensive income and into retained earnings with no impact to total shareholders’ equity or net income. In August 2018, the FASB issued guidance that aligns the requirements for capitalizing cloud computing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The accounting for the service element of a hosting arrangement that is a service contract is not affected by the guidance. The guidance was adopted by the Company in the third quarter of 2018 using prospective application and did not have a material impact on our financial statements. In March 2017, the FASB issued guidance that changed how employers that sponsor defined benefit pension and other postretirement benefit plans present the cost of the benefits in the income statement. Under the new guidance, employers will present only the service cost component of the net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. In addition, only the service cost component will be eligible for capitalization in assets. Employers will present the other components separately from the line item that includes the service cost and outside of any subtotal of operating income. Other components of net periodic benefit cost are presented in other non-operating income on the condensed consolidated statement of income. The guidance was adopted by the Company in the first quarter of 2018, using the practical expedient permitting the use of the amounts disclosed in pension and other postretirement benefit plan notes as the estimation basis for the presentation of the prior comparative periods. The income statement reclassifications are summarized as follows: Three Months Ended December 31, 2017 (in millions) As reported Reclassification As reclassified Income statement: Cost of products sold $ 809.9 $ (0.1 ) $ 809.8 Selling, general, and administrative expenses 93.6 1.1 94.7 Restructuring and other costs 29.4 (10.1 ) 19.3 Other non-operating (income) expense (0.6 ) 9.1 8.5 Twelve Months Ended December 31, 2017 (in millions) As reported Reclassification As reclassified Income statement: Cost of products sold $ 3,261.0 $ (1.0 ) $ 3,260.0 Selling, general, and administrative expenses 380.4 4.8 385.2 Restructuring and other costs 70.5 (10.1 ) 60.4 Other non-operating (income) expense (2.8 ) 6.3 3.5 In January 2017, the FASB issued new guidance that narrows the application of when an integrated set of assets and activities is considered a business and provides a framework to assist entities in evaluating whether both an input and a substantive process are present to be considered a business. The guidance was adopted by the Company in the first quarter of 2018. In August 2016, the FASB issued guidance to simplify elements of cash flow classification. The guidance is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The new guidance requires cash payments for debt prepayment or debt extinguishment costs to be classified as cash outflows for financing activities. It also requires cash payments made soon after an acquisition's consummation date (approximately three months or less) to be classified as cash outflows for investing activities. Payments made thereafter should be classified as cash outflows for financing activities up to the amount of the original contingent consideration liability. Payments made in excess of the amount of the original contingent consideration liability should be classified as cash outflows for operating activities. The guidance was adopted by the Company in the first quarter of 2018. 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. We adopted the new revenue guidance on January 1, 2018 using the modified retrospective application transition method. We elected the practical expedient to apply the new revenue standard to only contracts that were not completed as of January 1, 2018. Adoption did not have an impact on our financial statements, but did significantly impact our disclosures for revenue. Refer to Note 2 for updated revenue disclosures which are required by the new guidance. Recently Issued Accounting Standards In August 2017, the FASB issued guidance that amends the hedge accounting rules to better portray the economic results of risk management activities in the financial statements and also to make targeted improvements to simplify the application of hedge accounting guidance. The guidance will be adopted by the Company in the first quarter of 2019. The Company has evaluated the standard and has determined it to have an immaterial impact 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. Development of the selected leasing software is ongoing given the software vendor is still working to resolve performance and calculation issues. The timely availability of the lease software solution is critical to ensure an efficient and effective adoption of the standard. The Company will adopt the guidance in January 2019 when the guidance becomes effective. 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 $ 35 million to $ 55 million with an immaterial impact on our Consolidated Statement of Income; however, this estimate is subject to change as we finalize our implementation and resolve software issues.

Fair Value Disclosures [Abstract]
Financial Assets and Financial Liabilities Measured at Fair Value	FINANCIAL ASSETS AND FINANCIAL LIABILITIES MEASURED AT FAIR VALUE 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 include cash and cash equivalents, trade receivables, accounts payable, short-term borrowings, and long-term debt. At December 31, 2018 and 2017 , 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 measurements of the Company’s long-term debt represent non-active market exchange-traded securities which are valued at quoted prices or using input prices that are directly observable or indirectly observable through corroboration with observable market data. The carrying values and estimated fair values of long-term debt at December 31, 2018 and 2017 follow: December 31, 2018 December 31, 2017 Carrying Fair Value Carrying Fair Value (in millions) Value (Level 2) Value (Level 2) Total long-term debt $ 1,348.6 $ 1,342.0 $ 1,542.4 $ 1,591.0 The fair values for derivatives are based on inputs other than quoted prices that are observable for the asset or liability. These inputs include interest rates. The financial assets and financial liabilities are primarily valued using standard calculations / models that use as their basis readily observable market parameters. Industry standard data providers are the primary source for forward and spot rate information for both interest rates and currency rates, with resulting valuations periodically validated through third-party or counterparty quotes.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	DERIVATIVE INSTRUMENTS The Company enters into derivative transactions to manage exposures arising in the normal course of business. The Company does not enter into derivative transactions for speculative or trading purposes. The Company recognizes all derivative instruments on the balance sheet at fair value. 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. The Company enters into interest-rate swap contracts to economically convert a portion of the Company’s fixed-rate debt to variable rate debt. During the fourth quarter of 2011, the Company entered into four interest rate swap agreements with a total notional amount of $ 400 million . These contracts were designated as fair value hedges of the Company’s $ 400 million 4.5% fixed-rate debt due in 2021. The variable rate for each of the interest rate swaps is based on the six-month London Interbank Offered Rate (LIBOR), set in arrears, plus a fixed spread. The variable rates are reset semi-annually at each net settlement date. Fair values of these interest rate swaps are determined using discounted cash flow or other appropriate methodologies. Asset positions are included in deferred charges and other assets with a corresponding increase in long-term debt. Liability positions are included in other liabilities and deferred credits with a corresponding decrease in long-term debt. The Company enters into forward exchange contracts to manage foreign currency exchange rate exposures associated with certain foreign currency denominated receivables and payables. Forward exchange contracts generally have maturities of less than six months and relate primarily to the U.S. dollar for the Company’s Brazilian operations. The Company has not designated these derivative instruments as hedging instruments. At December 31, 2018 and 2017 , the Company had outstanding forward exchange contracts with notional amounts aggregating to $ 0.3 million and $ 2.7 million , respectively. The net settlement amount (fair value) related to active forward exchange contracts is recorded on the balance sheet as either a current or long-term asset or liability and as an element of other operating income which offsets the related transaction gains or losses. The net settlement amounts are immaterial for all periods presented. The Company is exposed to credit loss in the event of non-performance by counterparties in forward exchange contracts and interest-rate swap contracts. Collateral is generally not required of the counterparties or of the Company. In the event a counterparty fails to meet the contractual terms of a currency swap or forward exchange contract, the Company’s risk is limited to the fair value of the instrument. The Company actively monitors its exposure to credit risk through the use of credit approvals and credit limits, and by selecting major international banks and financial institutions as counterparties. The Company has not had any historical instances of non-performance by any counterparties, nor does it anticipate any future instances of non-performance. The fair values, balance sheet presentation, and the hedge designation status of derivative instruments at December 31, 2018 and 2017 are presented in the table below: Fair Value (Level 2) as of (in millions) Balance Sheet Location December 31, 2018 December 31, 2017 Asset Derivatives Interest rate swaps — designated as hedge Deferred charges and other assets $ — $ — Liability Derivatives Interest rate swaps — designated as hedge Other liabilities and deferred credits 2.7 0.6 The income statement impact of derivatives are presented in the table below: Amount of Gain (Loss) Recognized in Income on Derivatives (in millions) Income Statement Location 2018 2017 2016 Designated as hedges Interest rate swaps Interest expense $ (1.7 ) $ 3.2 $ 4.7 Not designated as hedges Forward exchange contracts Other operating income (1.0 ) (0.8 ) (0.8 ) Total $ (2.7 ) $ 2.4 $ 3.9

The Company reviews goodwill for impairment annually in the fourth quarter of the fiscal year and whenever events or changes in circumstances indicate that the carrying value of goodwill might not be recoverable. In 2018, the Company’s annual impairment test of the U.S. Packaging and Rest of World Packaging reporting unit concluded that the estimated fair value of these reporting units exceeded their carrying value and therefore their associated goodwill was not impaired. In 2017, as part of the Company’s annual assessment of impairment of goodwill conducted with the aid of a third party valuation specialist, the Company determined that the fair value of the Latin America Packaging reporting unit was less than its carrying value by approximately $ 163 million , primarily related to the Company’s revised expectations for the forecasted recovery in Brazil. This resulted in a full impairment of the Latin America Packaging reporting unit’s goodwill of $ 196.6 million ($ 145.5 million after tax). The Company’s annual impairment test of the U.S. Packaging reporting unit and Rest of World Packaging reporting unit in the fourth quarter of 2017 concluded that the estimated fair value of these reporting units exceeded their carrying value and therefore their associated goodwill was not impaired. The Company does not have any other accumulated impairment losses.

Pension and Other Postretirement Benefits Disclosure [Text Block]	PENSION PLANS Total defined benefit, defined contribution, and multiemployer plan pension expense in 2018 , 2017 , and 2016 was $ 36.7 million , $ 45.0 million , and $ 32.1 million , respectively. The Company sponsors 401(k) savings plans (defined contribution plans) for substantially all U.S. employees. For salaried employees, the Company contributed $ 1.00 for every pre-tax $ 1.00 an employee contributed up to seven percent in 2018 and up to eight percent in 2017 and 2016 of eligible compensation. For non-union hourly employees, the Company matched up to eight percent of eligible compensation in 2018, 2017 and 2016. The Company contributions are invested in target retirement date funds based on employees’ ages and are fully vested after three years of service. In 2016, the Company contributed $ 0.50 for every pre-tax $ 1.00 an employee contributed on the first four percent of eligible compensation plus $ 0.25 for every pre-tax $ 1.00 an employee contributed on the next four percent of eligible compensation for the plans that included a company match. The Company contributions in these years were invested in Company stock and were fully vested after three years of service. Total Company contributions for 2018 , 2017 , and 2016 were $ 25.1 million , $ 28.4 million , and $ 10.6 million , respectively. For employees not participating in defined benefit pension plans, the Company contributed to profit sharing plans, defined contribution plans which are subject to achievement of certain financial performance goals of the Company. The profit sharing plan covering salaried and non-union hourly employees was terminated for years after 2016. Total contribution expense for profit sharing plans and other defined contribution plans (including a multiemployer defined contribution plan which the Company exited in 2016, and excluding 401(k) plans above) was $ 3.0 million in 2018 , $ 2.0 million in 2017 , and $ 11.1 million in 2016 . Two of the Company's three U.S. defined benefit plans were frozen as of December 31, 2013. The frozen plans are the salaried retirement plan that covered certain salaried employees and the unfunded supplemental retirement plan that provided senior management with benefits in excess of limits under the federal tax law. The Company’s defined benefit pension plans continue to cover a number of U.S. hourly employees, and the non-U.S. defined benefit plans cover select employees at various international locations. The benefits under the plans are based on years of service and salary levels. Certain plans covering hourly employees provide benefits of stated amounts for each year of service. In 2014, the Society of Actuaries released updated mortality tables and a mortality projection scale which the Company adopted to measure defined benefit plan liabilities. In 2017 and 2018, the Society of Actuaries published new mortality projection scales which were used in conjunction with 2014 mortality tables in measuring defined benefit plan liabilities in 2017 and 2018. In 2017 and 2016, the Company recognized pension settlement charges, related to lump sum payments from U.S. pension plans, of $ 10.6 million and $ 5.8 million , respectively. Lump sum payments decrease the benefit obligation and are reflected as benefits paid in the "Change in Benefit Obligation" table. The payments also decrease plan assets and are reflected as benefits paid in the "Change in Plan Assets" table. During 2017 and 2016, lump sum windows were offered to certain participants of the salaried and hourly defined pension plans which resulted in lump sum payments for $ 41.6 million and $ 26.3 million , respectively. Settlement accounting was required in 2017 which resulted in the $ 10.6 million settlement charge. No charge was required in 2016.

The employer contributions for the years ended December 31, 2018 and 2017 , were $ 2.0 million and $ 4.0 million , respectively. Total expected cash contributions for 2019 are $ 2.0 million , which are expected to satisfy plan and regulatory funding requirements. For the years ended December 31, 2018 and 2017 , the U.S. pension plans represented approximately 92 percent and 92 percent , respectively, of the Company’s total plan assets and approximately 92 percent and 91 percent , respectively, of the Company’s total projected benefit obligation. Considering the significance of the U.S. pension plans in comparison with the Company’s total pension plans, the critical pension assumptions related to the U.S. pension plans and the non-U.S. pension plans are separately presented and discussed below. The Company’s actuarial valuation date is December 31. The weighted-average discount rates and rates of increase in future compensation levels used in determining the actuarial present value of the projected benefit obligation for the years ended December 31 are as follows: U.S. Pension Plans Non-U.S. Pension Plans 2018 2017 2018 2017 Weighted-average discount rate 4.25 % 3.75 % 3.33 % 2.80 % Rate of increase in future compensation levels — — 3.58 % 3.48 % The weighted-average discount rates, expected returns on plan assets, and rates of increase in future compensation levels used to determine the net benefit cost for the years ended December 31 are as follows: U.S. Pension Plans Non-U.S. Pension Plans 2018 2017 2016 2018 2017 2016 Weighted-average discount rate 3.75 % 4.21 % 4.25 % 2.80 % 3.05 % 3.96 % Expected return on plan assets 6.75 % 7.25 % 7.50 % 5.27 % 5.30 % 6.08 % Rate of increase in future compensation levels — — — 3.48 % 3.48 % 3.71 % The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid: (in millions) U.S. Pension Plans Non-U.S. Pension Plans 2019 $ 38.4 $ 1.6 2020 38.8 1.6 2021 43.0 2.2 2022 40.3 2.1 2023 40.2 2.2 Years 2023-2027 202.2 12.0 The Company's ERISA Benefit Plan Committee is responsible for overseeing the investments of the pension plans. The overall investment strategy is to achieve a long-term rate of return that maintains an adequate funded ratio and minimizes the need for future contributions through diversification of asset types, investment strategies, and investment managers. A target asset allocation policy is used to balance investments in equity securities with investments in fixed income securities. Beginning in 2013, the Company adopted a liability responsive asset allocation policy that becomes more conservative as the funded status of the plans improve. The majority of pension plan assets relate to U.S. plans and the target allocation is currently to invest approximately 69 percent in long-term corporate fixed income securities and approximately 31 percent in return seeking funds. The return seeking funds primarily include investments in diversified portfolios of large cap and small cap companies. Fixed income securities include diversified investments across a broad spectrum of primarily investment-grade debt securities. To develop the expected long-term rate of return on assets assumption, the Company considered historical returns and future expectations. Using the Company’s 2018 target asset allocation based on a liability responsive asset allocation, the Company’s outside actuaries have used their independent economic model to calculate a range of expected long-term rates of return and, based on their results, the Company has determined these assumptions to be reasonable. The pension plan assets measured at fair value at December 31, 2018 and 2017 follow: 2018 U.S. Pension Plans Non-U.S. Pension Plans Quoted Price In Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Quoted Price In Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in millions) (Level 1) (Level 2) (Level 3) (Level 1) (Level 2) (Level 3) Cash and cash equivalents $ 6.0 $ 1.2 $ — $ — $ — $ — Corporate debt securities — 243.4 — — — — U.S. government debt securities 5.3 — — — — — State and municipal debt securities — 13.8 — — — — Registered investment company funds — — — 44.2 — — Common trust funds — 296.9 — — 3.7 1.5 General insurance account — — — — — — Balance at December 31, 2018 $ 11.3 $ 555.3 $ — $ 44.2 $ 3.7 $ 1.5 2017 U.S. Pension Plans Non-U.S. Pension Plans Quoted Price In Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Quoted Price In Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in millions) (Level 1) (Level 2) (Level 3) (Level 1) (Level 2) (Level 3) Cash and cash equivalents $ 6.5 $ 2.0 $ — $ — $ — $ — Corporate debt securities — 257.9 — — — — U.S. government debt securities 4.0 — — — — — State and municipal debt securities — 16.9 — — — — Corporate common stock — — — — — — Registered investment company funds — — — 50.8 — — Common trust funds — 360.0 — — 4.8 — General insurance account — — — — — 1.5 Balance at December 31, 2017 $ 10.5 $ 636.8 $ — $ 50.8 $ 4.8 $ 1.5 Cash and cash equivalents. This category consists of direct cash holdings and institutional short-term investment vehicles. Direct cash holdings are valued based on cost, which approximates fair value and are classified as Level 1. Institutional short-term investment vehicles are valued daily and are classified as Level 2. Corporate, U.S. government, state, and municipal debt securities . These securities are 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. Corporate common stock. This category includes common and preferred stocks and index mutual funds that track U.S. and foreign indices. Fair values for the common and preferred stocks are based on quoted prices in active markets and were therefore classified within Level 1 of the fair value hierarchy. The mutual funds were valued at the unit prices established by the funds' sponsors based on the fair value of the assets underlying the funds. Since the units of the funds are not actively traded, the fair value measurements have been classified within Level 2 of the fair value hierarchy. Registered investment company funds. This category includes mutual funds that are actively traded on public exchanges. The funds are invested in equity and debt securities that are actively traded on public exchanges. Common trust funds. Common trust funds consist of shares in commingled funds that are not publicly traded. The funds are invested in equity and debt securities that are actively traded on public exchanges. General insurance account. The general insurance account is primarily comprised of insurance contracts that guarantee a minimum return. The reconciliation of the beginning and ending balances of the fair value measurements using significant unobservable inputs (Level 3) for the years ended December 31, 2018 and 2017 follows: (in millions) General Insurance Account Fair value of plan assets at December 31, 2016 $ 1.2 Actual return on plan assets 0.1 Foreign currency exchange rate changes 0.2 Fair value of plan assets at December 31, 2017 1.5 Actual return on plan assets — Foreign currency exchange rate changes — Fair value of plan assets at December 31, 2018 $ 1.5

Pension and Other Postretirement Benefits Disclosure [Text Block]	POSTRETIREMENT BENEFITS OTHER THAN PENSIONS The Company sponsors several defined postretirement benefit plans that provide healthcare benefits and, in some instances, provide life insurance benefits to certain employees. Further health care benefit accruals for all persons entitled to benefits under these plans were frozen as of March 31, 2014. Effective February 1, 2016, participants under the age of 50 as of March 1, 2016, were no longer eligible for the postretirement health care plans. Postretirement health care plans are contributory, with retiree contributions adjusted annually. Life insurance plans are noncontributory. Net periodic postretirement benefit costs included the following components for the years ended December 31, 2018 , 2017 , and 2016 : (in millions) 2018 2017 2016 Interest cost on accumulated postretirement benefit obligation $ 0.1 $ 0.2 $ 0.2 Amortization of prior service credit (0.3 ) (0.3 ) (0.3 ) Recognized actuarial net gain (1.1 ) (0.8 ) (0.7 ) Net periodic postretirement benefit income $ (1.3 ) $ (0.9 ) $ (0.8 ) Changes in benefit obligation and plan assets, and a reconciliation of the funded status at December 31, 2018 and 2017 , are as follows: (in millions) 2018 2017 Change in Benefit Obligation Benefit obligation at the beginning of the year $ 2.3 $ 4.2 Interest cost 0.1 0.2 Participant contributions 0.6 0.6 Plan amendments (0.2 ) — Actuarial gain (0.3 ) (1.8 ) Benefits paid (0.8 ) (0.9 ) Benefit obligation at the end of the year $ 1.7 $ 2.3 Change in Plan Assets Fair value of plan assets at the beginning of the year $ — $ — Participant contributions 0.6 0.6 Employer contributions 0.2 0.3 Benefits paid (0.8 ) (0.9 ) Fair value of plan assets at the end of the year $ — $ — Unfunded status at year end: $ (1.7 ) $ (2.3 ) (in millions) 2018 2017 Amount recognized in consolidated balance sheet consists of: Accrued benefit liability, current $ (0.2 ) $ (0.3 ) Accrued benefit liability, non-current (1.5 ) (2.0 ) Sub-total (1.7 ) (2.3 ) Deferred tax liability (1.3 ) (2.5 ) Accumulated other comprehensive income (4.0 ) (3.7 ) Net amount related to postretirement benefit plans $ (7.0 ) $ (8.5 ) Accumulated other comprehensive income related to other postretirement benefit plans is as follows: (in millions) 2018 2017 Unrecognized net actuarial gains $ (5.0 ) $ (5.8 ) Net prior service credits (0.3 ) (0.4 ) Tax expense 1.3 2.5 Accumulated other comprehensive income, end of year $ (4.0 ) $ (3.7 ) Estimated amounts in accumulated other comprehensive income expected to be reclassified to net period cost during 2019 are as follows: (in millions) Net actuarial gains $ 1.1 Net prior service credits 0.2 Net amount to be reclassified to net period cost $ 1.3 The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid: (in millions) Benefit Payments 2019 $ 0.3 2020 0.2 2021 0.2 2022 0.2 2023 0.2 Years 2023 - 2027 0.7 The employer contributions for the years ended December 31, 2018 and 2017 were $ 0.2 million and $ 0.3 million , respectively. The expected contribution for 2019 is $ 0.3 million , which is expected to satisfy plan funding requirements. The health care cost trend rate assumption affects the amounts reported. For measurement purposes, the assumed annual rate of increase in the per capita cost of covered health care benefits was 6.25 percent for 2018 and 6.50 percent for 2017 ; each year's estimated rate was assumed to decrease 0.25 percent annually to 5.0 percent and remain at that level thereafter. A one-percentage point change in assumed health care trends would have a nominal effect on both the total of service and interest cost components for 2018 and the post retirement benefit obligations at December 31, 2018. The Company’s actuarial valuation date is December 31. The weighted-average discount rate used to determine the actuarial present value of the net postretirement projected benefit obligation for each of the years ended December 31, 2018 and 2017 was 4.25 percent . The weighted-average discount rates used to determine the net postretirement benefit cost was 3.75 percent for the year ended December 31, 2018 , and 4.25 percent for the years ended 2017 , and 2016 .

Share-based Compensation Arrangement by Share-based Payment Award [Line Items]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	STOCK INCENTIVE PLANS The Company's 2014 Stock Incentive Plan provides for the issuance of up to 3,282,170 shares of common stock to certain employees and the Company's Board of Directors. As of December 31, 2018 , 1,290,386 shares were available for future grants under the 2014 Stock Incentive Plan. Shares subject to awards that are forfeited by an employee under the 2014 Stock Incentive Plan become available for future grants under the 2014 Stock Incentive Plan. Distribution of stock awards is made in the form of shares of the Company’s common stock on a one for one basis. Distribution of the shares will normally be made three years from the date of the stock award grant to an employee. Prior to 2016, stock awards for directors were fully vested upon grant. Beginning in 2016, stock awards for directors generally vest one year from the date of the grant. All other stock awards granted under the plans are subject to restrictions as to continuous employment, except in the case of death, permanent disability, retirement or change in control. Total compensation expense related to stock incentive plans was $ 19.6 million in 2018 , $ 17.4 million in 2017 , and $ 18.1 million in 2016 . As of December 31, 2018 , the unrecorded compensation cost for stock awards was $ 20.1 million and will be recognized over the remaining vesting period for each grant which ranges between 2019 and 2021. The remaining weighted-average life of all stock awards outstanding as of December 31, 2018 was 1.01 years. These awards are considered equity-based awards and are therefore classified as a component of additional paid-in capital. Cash payments equal to dividends accrued on awards during the vesting period are distributed at the same time as the shares of common stock to which they relate. Time-Based Stock Awards The cost of time-based stock awards is based on the fair market value of the Company's common stock on the date of grant and is charged to income on a straight-line basis over the requisite service period. The per share fair value of time-based stock awards granted during the years ended December 31, 2018, 2017 and 2016 was $ 46.30 , $ 48.10 , and $ 45.56 , respectively. Performance-Based Stock Awards Grantees of performance-based awards will be eligible to receive shares of the Company's common stock depending upon the Company's total shareholder return, assuming reinvestment of all dividends, relative to the performance of the Company's comparator group over a three-year period. The per share fair value of performance-based awards granted during the years ended December 31, 2018, 2017 and 2016 was $ 54.10 , $ 53.43 , and $ 48.48 , respectively, which the Company determined using a Monte Carlo simulation and the following assumptions: 2018 2017 2016 Average risk-free interest rate 2.01 % 1.50 % 1.31 % Expected volatility (Bemis Company, Inc.) 20.0 % 17.7 % 16.3 % The average risk-free interest rate is based on the three-year U.S. treasury security rate in effect as of the grant date. The expected volatilities were determined using daily historical volatility for the most recent three-year period as of the grant date. In 2019, there was an 87.5 percent payout of 2016 awards, and the balance was forfeited. In 2018, there was a 62.5 percent payout of 2015 awards, and the balance was forfeited. In 2017, there was a 94.7 percent payout of 2014 awards, and the balance was forfeited. In 2016, there was a 93.7 percent payout of 2013 awards, and the balance was forfeited.

The Company's foreign tax rate differential is largely the result of a higher statutory rate in Brazil. The effective tax rate for 2017 differs from the other years due primarily to the impairment of the Latin America Packaging reporting unit’s goodwill and new tax legislation in the U.S. In the fourth quarter of 2017, the Company recorded a full impairment of the Latin America Packaging reporting unit’s goodwill which included a $ 51.1 million deferred tax benefit related to tax deductible goodwill. The tax rate reconciliation schedule reflects the difference between the statutory rates in Latin America and the U.S. as well as the non-deductible portion of the impaired goodwill. On December 22, 2017, the President of the United States signed comprehensive tax legislation commonly referred to as the TCJA. The TCJA made broad and complex changes to the U.S. tax code which impacted the Company’s years ended 2017 and 2018 including, but not limited to (1) reducing the U.S. federal corporate tax rate, (2) requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that may be paid over eight years, and (3) accelerating expensing of certain capital expenditures. The TCJA reduced the federal corporate tax rate from 35 percent to 21 percent effective January 1, 2018. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed in reasonable detail to complete the accounting for the TCJA. The Company has recognized the provisional tax impacts related to deemed repatriated earnings and the revaluation of deferred tax assets and liabilities and included these amounts in its consolidated financial statements for the year ended December 31, 2017. The Company recorded a provisional discrete net tax benefit of $ 67.2 million related to the TCJA in the year ended December 31, 2017. This consisted of a $ 77.8 million net benefit due to the remeasurement of the Company’s deferred tax accounts for the corporate rate reduction and a net expense for the transition tax of $ 10.6 million . The adjustments to these provisional amounts are discussed below. Reduction in U.S. Corporate Rate: The TCJA reduced the statutory corporate tax rate to 21 percent for the Company’s tax years ending in 2018 and beyond. While the Company was able to make a reasonable estimate of the impact of the reduction in corporate rate, the Company continued to analyze the temporary differences that existed on the date of enactment throughout 2018. The Company recognized a measurement-period benefit of $ 5.0 million related to temporary differences. The benefit of the measurement-period adjustment on the 2018 effective tax rate was a benefit of 1.8%. The calculation of the adjustment to temporary differences is now complete and resulted in recording a total net benefit of $5.0 million to income tax expense in 2018. Transition Tax: The transition tax is a 2017 tax on the previously untaxed accumulated and current earnings and profits ("E&P") of the Company’s foreign subsidiaries. To calculate the transition tax, the Company determined the post-1986 E&P of the subsidiaries, as well as non-U.S. income taxes paid on such earnings, in addition to other factors. E&P is similar to retained earnings of the subsidiary but requires other adjustments to conform to U.S. tax rules. The Company recorded an estimated transition tax obligation expected to be paid over eight years beginning in 2018. These amounts were presented in Accrued income and other taxes and Other liabilities and deferred credits. On the basis of revised E&P computations and published guidance, the Company recognized a measurement-period adjustment of $ 3.2 million related to the overall transition tax obligation. The effect of the measurement-period adjustment on the 2018 effective tax rate was a benefit of 1.1%. The transition tax, which has now been determined to be complete, resulted in recording a net transition tax obligation of $ 7.4 million, with a corresponding net benefit of $ 3.2 million to income tax expense in 2018. Due to IRS rules regarding the application of overpayments, the entire liability was paid in full in 2018. Global Intangible Low-Taxed Income ("GILTI"): The TCJA includes a provision designed to tax certain low taxed income starting in 2018. The Company currently estimates GILTI will be immaterial for the year ended December 31, 2018, although interpretive guidance continues to be issued and future guidance may impact this analysis. The Company has not recorded any deferred taxes for future GILTI inclusions. The Company has $ 293.8 million of undistributed earnings of foreign subsidiaries which are considered to be indefinitely reinvested in the operations of those subsidiaries. As a result of the transition tax mentioned above, the Company estimates that minimal federal and state income tax would be due upon the actual remittance of the undistributed earnings. In addition, the Company also estimates minimal foreign withholding tax on any potential remittance. As of December 31, 2018 , the Company had foreign net operating loss carryovers of approximately $ 71.0 million that are available to offset future taxable income. Approximately $ 12.2 million of the carryover expires over the period 2019-2033. The remaining balance has no expiration. In addition, the Company had $ 15.1 million of foreign tax credit carryover that is available to offset future tax. This carryover expires over the period 2023-2024. Current authoritative guidance issued by the FASB requires that a valuation allowance be established when it is more likely than not that all or a portion of deferred tax assets will not be realized. The Company has, and continues to generate, both net operating losses and deferred tax assets in certain jurisdictions for which a valuation allowance is required. The tax rate reconciliation reflects the recording of a valuation allowance of $ 5.2 million against certain deferred tax assets in Brazil in 2018. In total, the Company’s management has determined that a valuation allowance of $ 33.1 million and $ 48.5 million against deferred tax assets primarily associated with the foreign net operating loss carryover and the foreign tax credit carryover was necessary at December 31, 2018 and 2017 , respectively. The Company had total unrecognized tax benefits of $ 25.1 million and $35.2 million at December 31, 2018 and 2017 , respectively. The approximate amount of unrecognized tax benefits that would impact the effective income tax rate if recognized in any future periods was $ 25.1 million and $ 35.2 million for the years ended December 31, 2018 and 2017 , respectively. A reconciliation of the beginning and ending amount of unrecognized tax benefits, in millions, is as follows: 2018 2017 Balance at beginning of year $ 35.2 $ 32.9 Additions based on tax positions related to the current year 3.1 3.9 Additions for tax positions of prior years 2.0 4.1 Reductions for tax positions of prior years (3.0 ) (1.1 ) Reductions due to a lapse of the statute of limitations (11.8 ) (4.5 ) Settlements (0.4 ) (0.1 ) Balance at end of year $ 25.1 $ 35.2 The Company recognizes interest and penalties related to unrecognized tax benefits as components of income tax expense. The Company recognized $ 0.4 million of net tax benefit, $ 1.1 million of net tax expense and $ 1.2 million of net tax benefit related to interest and penalties during the years ended December 31, 2018, 2017 and 2016, respectively. The Company had approximately $ 11.5 million and $ 14.5 million accrued for interest and penalties, net of tax benefits, at December 31, 2018 and 2017 , respectively. As a result of acquisitions, the Company recorded $ 2.6 million of unrecognized tax benefits and $ 2.5 million of interest and penalties related to pre-acquisition tax positions in 2016 for which the Company is indemnified. Corresponding assets related to these indemnified provisions have also been recorded for these amounts. During the next 12 months it is reasonably possible that a reduction of gross unrecognized tax benefits will occur in an amount of up to $ 6.0 million , exclusive of currency movements, as a result of the resolution of positions taken on previously filed returns. The Company and its subsidiaries are subject to U.S. federal and state income tax as well as income tax in multiple international jurisdictions. The Company's U.S. federal income tax returns prior to 2015 are no longer subject to examination. With few exceptions, the Company is no longer subject to examinations by tax authorities for years prior to 2013 in the significant jurisdictions in which it operates.

Legal Proceedings

Legal Proceedings	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings	COMMITMENTS AND CONTINGENCIES The Company is involved in a number of lawsuits incidental to its business, including environmental-related litigation and routine litigation arising in the ordinary course of business. Although it is difficult to predict the ultimate outcome of these cases, the Company believes, except as discussed below, that any ultimate liability would not have a material adverse effect on the Company’s consolidated financial condition or results of operations. Environmental Matters The Company is a potentially responsible party ("PRP") pursuant to the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (commonly known as “Superfund”) and similar state and foreign laws in proceedings associated with 12 sites around the United States and one in Brazil. These proceedings were instituted by the United States Environmental Protection Agency and certain state and foreign environmental agencies at various times beginning in 1983. Superfund and similar state and foreign laws create liability for investigation and remediation in response to releases of hazardous substances in the environment. Under these statutes, joint and several liability may be imposed on waste generators, site owners and operators, and others regardless of fault. Although these regulations could require the Company to remove or mitigate the effects on the environment at various sites, perform remediation work at such sites, or pay damages for loss of use and non-use values, the Company expects its liability in these proceedings to be limited to monetary damages. The Company expects its future liability relative to these sites to be insignificant, individually and in the aggregate. The Company is involved in other environmental-related litigation arising in the ordinary course of business. The Company accrues environmental costs when it is probable that these costs will be incurred and can be reasonably estimated. The Company's reserve for environmental liabilities at December 31, 2018 and 2017 was $ 0.3 million and $ 0.9 million , respectively, and is included in other liabilities and deferred credits on the accompanying consolidated balance sheet. Brazil Tax Dispute - Goodwill Amortization During October 2013, Dixie Toga, Ltda ("Dixie Toga"), a Bemis subsidiary, received an income tax assessment in Brazil for the tax years 2009 through 2011 that relates to the amortization of certain goodwill generated from the acquisition of Dixie Toga. The income tax assessed for those years is approximately $ 9.8 million , translated to U.S. dollars at the December 31, 2018 exchange rate. The Company expects that tax examinations for years after 2011 will include similar assessments as the Company continues to claim the tax benefits associated with the goodwill amortization. An ultimate adverse resolution on these assessments, including interest and penalties, could be material to the Company's consolidated results of operations and/or cash flows. The Company has been advised by its legal and tax advisors that its position with respect to the deductions is allowable under the tax laws of Brazil. The Company is contesting the disallowance and believes it is more likely than not the tax benefit will be sustained in its entirety and consequently has not recorded a liability. In May of 2017, the Company received a favorable administrative decision. The government is appealing this decision to the next administrative level. The Company intends to litigate the matter if it is not resolved at the administrative appeals levels. The ultimate outcome could take several years. At this time, the Company believes that final resolution of the assessment will not have a material impact on the Company's consolidated financial statements. Brazil Tax Credits During October 2018, Bemis Do Brasil Industria E Comercio De Embalagens Ltda. (“Bemis Brazil”), a Bemis subsidiary, received a final decision from the Brazilian court regarding our claim that certain indirect taxes were incorrectly required to be paid in the years 2001 through 2017. As a result of this case, Bemis Brazil expects to receive tax credits for the overpaid tax and related interest that can be used to offset various Brazilian federal taxes in future years. The exact methodology to compute the amount of the tax credit is still being determined by the tax authorities. In the fourth quarter of 2018, Bemis Brazil hired an outside consultant to compile documentation required to claim the credit. Bemis Brazil has estimated that it is probable to receive a benefit, net of fees and applicable Brazilian taxes, of $ 10.1 million (translated into U.S. dollars as of December 31, 2018) for the years 2009-2017. We reflected the $ 10.1 million benefit by recording $ 15.3 million on the consolidated statement of income in other operating income offset by $ 5.2 million of income tax included within income taxes provision (benefit). Bemis Brazil has not completed the estimation of tax credits for the years 2001 through 2008 given the need to gather and review manual records from this time period. The completion of this estimate is expected in 2019 and will result in recording further benefits. In addition, a taxpayer favorable decision on the methodology to compute the tax credits may result in significantly more tax credits, subject to some limitations, being available to Bemis Brazil.

Segments of Business

Segment Reporting Information [Line Items]
Segments of Business	SEGMENTS OF BUSINESS The Company's business activities are organized around and aggregated into its three principal business segments, U.S. Packaging, Latin America Packaging and Rest of World Packaging, based on their similar economic characteristics, products, production process, types of customers, and distribution methods. Both internal and external reporting conforms to this organizational structure, with no significant differences in accounting policies applied. Intersegment sales (which are not significant) are generally priced to reflect nominal markups. The Company evaluates the performance of its segments and allocates resources to them based primarily on operating profit, which is defined as profit before restructuring and other costs, general corporate expense, goodwill impairment charges, interest expense, other non-operating income, and income taxes. Sales to the Kraft Heinz Company, and its subsidiaries, accounted for approximately 11 percent in 2018 and 10 percent in 2017 and 2016. The Company primarily sells to Kraft Heinz Company in the U.S. Packaging segment. Products produced within the U.S., Latin America and Rest of World Packaging business segments service packaging applications for markets such as food, medical devices, pharma, personal care, agribusiness, chemicals, pet food, and consumer products. A summary of the Company’s business activities reported by its three business segments follows: Business Segments (in millions) 2018 2017 2016 Sales including intersegment sales: U.S. Packaging $ 2,739.1 $ 2,666.0 $ 2,646.8 Latin America Packaging 631.8 715.2 707.0 Rest of World Packaging 773.9 721.4 696.4 Intersegment sales: U.S. Packaging (40.6 ) (40.0 ) (25.7 ) Latin America Packaging (3.2 ) (3.8 ) (3.9 ) Rest of World Packaging (11.1 ) (12.6 ) (16.2 ) Total net sales $ 4,089.9 $ 4,046.2 $ 4,004.4 Segment operating profit U.S. Packaging $ 360.2 $ 352.5 $ 400.0 Latin America Packaging 48.1 30.0 50.0 Rest of World Packaging 81.2 61.1 64.0 Restructuring and other costs 61.9 60.4 28.6 Goodwill impairment charge — 196.6 — General corporate expenses 68.6 64.6 74.1 Operating income 359.0 122.0 411.3 Interest expense 76.1 65.8 60.2 Other non-operating (income) loss (2.8 ) 3.5 0.2 Income before income taxes $ 285.7 $ 52.7 $ 350.9 Business Segments (in millions) 2018 2017 2016 Total assets (1): U.S. Packaging $ 2,082.5 $ 2,072.0 $ 2,007.7 Latin America Packaging 551.9 648.1 779.2 Rest of World Packaging 742.3 784.5 706.1 Corporate assets (2) 194.3 195.3 222.7 Total $ 3,571.0 $ 3,699.9 $ 3,715.7 Restructuring and other costs (3)(4): U.S. Packaging $ 11.5 $ 13.3 $ — Latin America Packaging 9.5 28.8 18.9 Rest of World Packaging 1.9 2.7 7.7 Corporate 39.0 15.6 2.0 Total $ 61.9 $ 60.4 $ 28.6 Depreciation and amortization: U.S. Packaging $ 96.6 $ 97.9 $ 93.7 Latin America Packaging 22.6 26.7 26.2 Rest of World Packaging 32.8 30.2 27.9 Corporate 15.6 15.0 14.3 Total $ 167.6 $ 169.8 $ 162.1 Additions to property and equipment: U.S. Packaging $ 75.5 $ 101.9 $ 131.2 Latin America Packaging 32.3 45.2 32.9 Rest of World Packaging 27.2 35.0 36.8 Corporate 8.5 6.4 7.4 Total $ 143.5 $ 188.5 $ 208.3 Operations by geographic area (in millions) 2018 2017 2016 Long-lived assets (5): United States $ 917.5 $ 957.4 $ 949.2 Brazil 191.6 223.6 212.9 Other Americas 48.4 51.9 44.1 Europe 90.7 93.3 75.1 Asia-Pacific 84.6 90.1 81.3 Total $ 1,332.8 $ 1,416.3 $ 1,362.6 (1) Total assets by business segment include only those assets that are specifically identified with each segment’s operations.

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of consolidation: The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All intercompany transactions and accounts have been eliminated. Joint ventures which are not majority controlled are accounted for by the equity method of accounting with earnings of $ 2.3 million , $ 2.9 million , and $ 2.2 million in 2018 , 2017 , and 2016 , respectively, included in other operating income on the accompanying consolidated statement of income. Investments in joint ventures of $ 6.9 million and $ 8.9 million as of December 31, 2018 and 2017 , respectively, are included in deferred charges and other assets on the accompanying consolidated balance sheet.
Use of Estimates, Policy [Policy Text Block]	Estimates and assumptions required: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Translation of foreign currencies: The Company considers the local currency to be the functional currency for substantially all foreign subsidiaries. Assets and liabilities are translated at the exchange rate as of the balance sheet date. All revenue and expense accounts are translated at average exchange rates in effect during the year. Translation gains or losses are recorded in the foreign currency translation component in accumulated other comprehensive loss in shareholders’ equity. Foreign currency transaction losses of $ 0.3 million and $ 0.6 million in 2018 and 2017, respectively, and gains of $ 0.4 million in 2016 , are included as a component of other operating income. Foreign currency transaction losses of $ 0.7 million were recorded within non-operating income in 2016. There were no foreign currency transaction losses recorded within non-operating income in 2018 or 2017.
Revenue Recognition, Policy [Policy Text Block]	Revenue recognition:
Research and Development Expense, Policy [Policy Text Block]	Research and development: Research and development expenditures are expensed as incurred.
Facility Consolidation and Other Costs [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 for locations outside the U.S., 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: Trade accounts receivable 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. Based on management’s assessment, the Company provides for estimated uncollectible amounts through a charge to earnings and a credit to allowance for doubtful accounts. Balances that remain outstanding after the Company has used reasonable collection efforts are written off through a charge to the allowance for doubtful accounts and a credit to trade receivables. Trade receivables are presented net of an allowance for doubtful accounts of $ 16.4 million and $ 17.7 million at December 31, 2018 and 2017 , respectively. The Company enters into supply chain financing programs from time to time to sell trade receivables without recourse to third-party financial institutions. Sales of trade receivables are reflected as a reduction of trade receivables on the consolidated balance sheets and the proceeds are included in the cash flows from operating activities in the consolidated statements of cash flows. During both the years ended December 31, 2018 and 2017, the Company sold without recourse trade receivables representing approximately 20 percent of net sales, and the associated discount on sale of trade receivables was not significant.
Inventory, Policy [Policy Text Block]	Inventory valuation: 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 December 31, as follows: (in millions) 2018 2017 Raw materials and supplies $ 197.4 $ 198.3 Work in process and finished goods 422.1 421.9 Total inventories $ 619.5 $ 620.2
Property, Plant and Equipment, Policy [Policy Text Block]	Property and equipment: Property and equipment are stated at cost. Maintenance and repairs that do not improve efficiency or extend economic life are expensed as incurred. Plant and equipment are depreciated for financial reporting purposes principally using the straight-line method over the estimated useful lives of assets as follows: land improvements, 15 - 30 years; buildings, 15 - 45 years; leasehold and building improvements, the lesser of the lease term or 8 - 20 years; and machinery and equipment, 3 - 17 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 as deferred income taxes. Depreciation expense was $ 150.7 million , $ 152.8 million , and $ 146.1 million for 2018 , 2017 , and 2016 , respectively. On sale or retirement, the asset cost and related accumulated depreciation are removed from the accounts and any related gain or loss is reflected in other operating income. The Company reviews its long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of the assets 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. The Company capitalizes direct costs (internal and external) of materials and services used in the development and purchase of internal-use software. Amounts capitalized are amortized on a straight-line basis over a period of three to twelve years and are reported as a component of machinery and equipment within property and equipment. The Company is in the process of developing and implementing a new Enterprise Resource Planning ("ERP") system. Certain costs incurred during the application development stage have been capitalized in accordance with authoritative accounting guidance related to accounting for costs of computer software developed or obtained for internal use. The net book value of capitalized costs for this new ERP system were approximately $ 47.6 million and $ 55.0 million as of December 31, 2018 and 2017 , respectively. These costs are being amortized over the system’s estimated useful life as the ERP system is placed in service.
Goodwill and Intangible Assets, Intangible Assets, Indefinite-Lived, 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. 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. The Company has two reporting units with goodwill that is assessed for potential impairment. All goodwill is assigned to reporting units, which is defined as the operating segment, or one level below the operating segment. The Company has three reporting units, or operating segments, which align with the Company's reportable segment structure. Accounting guidance allows the Company to first perform a qualitative assessment about the likelihood of the carrying value of a reporting unit exceeding its fair value, referred to as the "Step 0" assessment. The Step 0 assessment requires the evaluation of certain qualitative factors, including macroeconomic conditions, industry and market considerations, cost factors and overall financial performance, as well as company and reporting unit factors. If the Company's Step 0 analysis indicates that it is more likely than not that the fair value of a reporting unit is less than the carrying amount, then the Company would perform a quantitative impairment test. The Company applied the Step 0 assessment to its two reporting units with goodwill in 2018 given the reporting units both had fair values significantly in excess of their carrying amounts when tested in 2017. The Company's Step 0 analysis in 2018 of the reporting units concluded that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount. Therefore, the quantitative goodwill impairment test for these reporting units was not necessary in 2018. In assessing goodwill for impairment the Company performed a two-step goodwill impairment test in 2016 and adopted the new accounting guidance for 2017, Accounting Standards Update 2017-04, Simplifying the Test for Goodwill Impairment , which allows for a single step method. Both approaches utilize two valuation approaches, the income approach and the market multiple approach. Under the income approach, the Company estimates the fair value of the reporting unit based on the present value of estimated future cash flows. Cash flow projections are based on management’s estimates of revenue growth rates and EBITDA margins, taking into consideration business and market conditions for the countries and markets in which the reporting unit operates. The Company calculates the discount rate based on a market-participant, risk-adjusted weighted average cost of capital, which considers industry specific rates of return on debt and equity capital for a target industry capital structure, adjusted for risks associated with business size and geography. Under the market multiples approach, the Company estimates fair value based on market multiples of EBITDA derived from publicly traded companies in the Company’s peer group, adjusted to reflect differences in size and growth prospects. During the second quarter of 2017, the Company initiated an interim impairment analysis of the Latin America Packaging reporting unit given the contraction in this reporting unit’s business late in the second quarter. This review did not result in any impairment of the reporting unit’s goodwill balance. As a result of further deterioration in the forecasted sales and profits of the Latin America Packaging reporting unit from the second quarter outlook and forecasted slow economic recovery, the Company determined in the fourth quarter of 2017 that the fair value of the reporting unit was less than its carrying value. In performing the analysis, the Company used discount rates and terminal growth rates of 11 percent and 3 percent , respectively, to calculate the present value of future cash flows. Accordingly, the Company recorded a noncash goodwill impairment charge of $ 196.6 million ($ 145.5 million after-tax) which is recorded in the goodwill impairment charge line of the consolidated income statement. The annual impairment test indicated the goodwill balances for the U.S. Packaging reporting unit and Rest of World Packaging reporting units were not impaired for the years ended December 31, 2018, 2017 or 2016 and the Company does not have any accumulated impairment losses for these reporting units.
Intangible Assets, Finite-Lived, Policy [Policy Text Block]	Intangible assets: 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 thirty 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 whenever there is an impairment indicator. The Company completed a test of the Latin America Packaging reporting unit intangibles in the fourth quarter of 2017 which concluded the assets were not impaired. Intangible assets are tested for impairment by comparing anticipated undiscounted future cash flows from operations to net book value.
Derivatives, Policy [Policy Text Block]	Financial instruments: The Company recognizes all derivative instruments on the balance sheet at fair value. 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 8 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.
Deferred Credits and Other Liabilities [Policy Text Block]	Other liabilities and deferred credits: Other liabilities and deferred credits balances include non-current pension and other postretirement liability amounts of $ 75.7 million and $ 47.6 million at December 31, 2018 and 2017 , respectively.
Stockholders' Equity, Policy [Policy Text Block]	Treasury stock: Treasury stock purchases are stated at cost and presented as a separate reduction of shareholders’ equity. During 2018, the Company did not purchase any common stock. During 2017, the Company purchased 2.2 million shares of common stock in the open market for $ 103.8 million . During 2016, the Company purchased 3.0 million shares of common stock in the open market for $ 143.9 million . At December 31, 2018 , approximately 18.2 million common shares can be repurchased, at management’s discretion, under authority granted by the Company’s Board of Directors.
