Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	SIGNIFICANT ACCOUNTING POLICIES
	Discontinued operations presentation: The consolidated statement of income and related notes have been recast from those presented in the previously filed Form 10-K to reflect our Pressure Sensitive Materials business as a discontinued operation (see Note 6 — Divestitures). The consolidated balance sheet at December 31, 2013 and related notes have not been recast to reflect the assets and liabilities divested. The consolidated statement of cash flows for all periods includes both continuing and discontinued operations.
	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 $1.7 million, $3.1 million, and $2.6 million in 2014, 2013, and 2012, respectively, included in other operating income on the accompanying consolidated statement of income.  Investments in joint ventures of $8.0 million and $7.7 million as of December 31, 2014 and 2013, respectively, are included in deferred charges and other assets on the accompanying consolidated balance sheet.
	In connection with the implementation of an enterprise resource planning system during 2012, the Company recorded adjustments primarily to cost of goods sold during the fourth quarter in order to align the application of certain accounting practices among the business segments. These adjustments substantially offset one another in the Company's consolidated financial statements. The $2.1 million consolidated expense is disaggregated by reportable segment in Note 20.
	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 $3.5 million, $2.6 million, and $1.7 million in 2014, 2013, and 2012, respectively, are included as a component of other operating income.  There were no foreign currency transaction losses recorded within non-operating income in 2014, 2013 or 2012.
	Revenue recognition:  Sales and related costs of products sold are recognized when persuasive evidence of an arrangement exists, title and risk of ownership have been transferred to the customer, the sales price is fixed or determinable, and collectability is reasonably assured.  These conditions are typically fulfilled upon shipment of products.  All costs associated with revenue, including customer rebates and provisions for estimates of sales returns and allowances, are recognized as a deduction from revenue in the period in which the associated revenue is recorded. Customer rebates are accrued using sales data and rebate percentages specific to each customer agreement. Shipping and handling costs are classified as a component of cost of products sold while amounts billed to customers for shipping and handling are classified as a component of sales. The Company accrues for estimated warranty costs when specific issues are identified and the amounts are determinable and also considers the history of actual claims paid. Taxes assessed by governmental authorities on revenue producing transactions, including sales, value added, excise and use taxes, are recorded on a net basis (excluded from revenue).
	Environmental cost:  The Company is involved in 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, 2014 and 2013 was $6.1 million and $7.6 million, respectively.  The Company made a favorable adjustment of $0.8 million in 2014 based on current estimates of liability. The Company made no other adjustments to the reserve accounts and costs which were directly expensed for environmental remediation matters resulted in charges to the income statements for each of the years 2014, 2013, and 2012.  There were no third party reimbursements for any of the years presented.
	Research and development:  Research and development expenditures are expensed as incurred.
	Facility consolidation and other costs:  Facility consolidation and other 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 facility consolidation 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 facility consolidation 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 facility consolidation costs, including costs to relocate equipment, are generally recorded as 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.
	Accounts receivable:  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 accounts receivable.  Accounts receivable are presented net of an allowance for doubtful accounts of $21.0 million and $30.7 million at December 31, 2014 and 2013, respectively.
	The Company enters into supply chain financing programs from time to time to sell accounts receivables without recourse to third-party financial institutions.  Sales of accounts receivable are reflected as a reduction of accounts receivable 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 the year ended December 31, 2014, the Company sold without recourse accounts receivable representing approximately five percent of net sales, and the associated discount on sale of accounts receivables was insignificant.
	Inventory valuation:  Inventories are valued at the lower of cost, as determined by the first-in, first-out (FIFO) method, or market.  Inventory values using the FIFO method of accounting approximate replacement cost.  Inventories are summarized at December 31, as follows:
	(in millions)	2014		2013
	Raw materials and supplies	$	193.9	$	215.6
	Work in process and finished goods	381.9		432.9
	Total inventories	$	575.8	$	648.5
	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, 3-16 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 $154.6 million, $162.2 million, and $175.5 million for 2014, 2013, and 2012, 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 income.  Interest costs, which are capitalized during the construction of major capital projects, totaled $0.2 million in 2014, $0.3 million in 2013, and $0.1 million in 2012.
	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 $69.9 million and $74.3 million as of December 31, 2014 and 2013, 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 business combinations.  Goodwill is not amortized, but instead tested annually or when events and circumstances indicate an impairment may have occurred. The Company's reporting units each contain 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, of which two are included in the Global Packaging reportable segment. The other reporting unit is the U.S. Packaging segment.
	Goodwill for the reporting units is reviewed for impairment annually in the fourth quarter of each year using a two-step process. In the first step, the fair value of each reporting unit is compared to its carrying value, including goodwill. The determination of the estimated fair value of the reporting units utilizes both a discounted cash flow valuation and a market multiple method. Significant inputs to the discounted cash flow valuation method include discount rates, long-term sales growth rates and forecasted operating margins. The market multiple method estimates fair value by comparing the Company to similar public companies. If the fair value exceeds the carrying value, step two is not required and an impairment loss is not recognized. If step two were required, the implied fair value of goodwill would be calculated by deducting the fair value of all tangible and intangible net assets, including unrecognized intangible assets, of the reporting unit from the fair value of the reporting unit. If the implied fair value of goodwill is less than the carrying value of goodwill, an impairment loss would be recognized equal to the difference.
	Current 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 two-step impairment test. The Company applied the Step 0 assessment to the U.S. Packaging reporting unit in 2014 and 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 two-step goodwill impairment test for this reporting unit was not necessary in 2014.
	The annual impairment test indicated no impairment for the years ended December 31, 2014, 2013, or 2012, nor does the Company have any accumulated impairment losses.
	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.  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 $102.4 million and $54.7 million at December 31, 2014 and 2013, respectively.
	Treasury stock:  Treasury stock purchases are stated at cost and presented as a separate reduction of shareholders’ equity.  During 2014, the Company purchased 3.8 million shares of common stock in the open market for $152.1 million. During 2013, the Company purchased 2.0 million shares of common stock in the open market for $77.3 million.  The Company did not purchase any shares of common stock during 2012.  At December 31, 2014, approximately 6.7 million common shares can be repurchased, at management’s discretion, under authority granted by the Company’s Board of Directors in 2014.

	In May 2014, the Financial Accounting Standards Board ("FASB") issued new guidance which supersedes current revenue recognition requirements.  This guidance is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  The guidance is required to be applied by the Company in the first quarter of fiscal 2017 using one of two retrospective application methods. The Company is currently evaluating the application methods and the impact of this new statement on the Company's consolidated financial position, results of operations, and cash flows.
	In April 2014, the FASB issued new guidance that redefines a discontinued operation as a component or group of components that has been disposed of or is classified as held for sale and represents a strategic shift that has (or will have) a major effect on an entity’s financial results. Continuing involvement will no longer preclude presentation as a discontinued operation. The guidance is required to be applied by the Company prospectively to new disposals and new classifications of disposal groups as held for sale beginning in fiscal 2015. While early adoption is permitted, the Company did not early adopt this guidance for its divestiture of its Pressure Sensitive Materials business. The Company does not expect the adoption of this standard will have a material impact on the consolidated financial statements.

Facility Consolidation and Other Costs	FACILITY CONSOLIDATION AND OTHER COSTS
	2011 Program
	During the fourth quarter of 2011, the Company initiated a facility consolidation and other costs program (“2011 Program”) to improve efficiencies and reduce fixed costs.  As a part of this program, the Company announced the closure of five facilities. As of December 31, 2013, manufacturing operations had ceased at all of these manufacturing facilities.  Most of the production from these five facilities has been transferred to other facilities.  The total 2011 Program costs were $97.2 million, including $33.4 million in employee costs, $34.7 million in fixed asset accelerated depreciation and write-downs, and $29.1 million in other facility consolidation costs.  These amounts exclude any potential gain to be recognized on the sale of property. The 2011 Program costs by reportable segment follow:
	(in millions)	U.S. Packaging		Global Packaging		Corporate		Total Facility
								Consolidation and Other Costs
	2011 net expense accrued	$	26.3	$	8.6	$	0.8	$	35.7

	Expense incurred through December 31, 2013	$	82.8	$	13.6	$	0.8	$	97.2
	2012 Program
	During the second quarter of 2012, the Company expanded its facility consolidation and other costs program (“2012 Program”) to further improve efficiencies and reduce costs within its U.S. and Global Packaging segments.  As a part of this program, the Company announced the closure of an additional four production locations, including three facilities outside of the U.S., and the relocation of the majority of the production to other facilities. As of December 31, 2013, manufacturing operations had ceased at all of these manufacturing facilities.  The total 2012 Program costs of $52.6 million included $21.9 million in employee-related costs, $16.5 million in fixed asset accelerated depreciation and write-downs, and $14.2 million in other facility consolidation costs.  The 2012 Program costs by reportable segment follow:
	(in millions)	U.S. Packaging		Global Packaging		Total Facility
						Consolidation and Other Costs
	2012 net expense accrued	$	12.7	$	21.6	$	34.3
	2013 net expense accrued	17.9		0.4		18.3
	Expense incurred through December 31, 2013	$	30.6	$	22	$	52.6
	Cash payments for these facility consolidation programs in 2013 and 2012 totaled $51.6 million and $35.2 million, respectively.  Cash payments in 2013 were net of proceeds of $9.8 million received for the sale of property and equipment. Cash payments in 2014 were minimal, and exclude the impact of proceeds on sale of property. The costs related to facility consolidation activities have been recorded on the consolidated statement of income as facility consolidation and other costs.

	Divestiture of Pressure Sensitive Materials Business
	On November 7, 2014, the Company completed the sale its global Pressure Sensitive Materials business. Net proceeds of the transaction totaled $136.9 million, subject to settlement of customary post-closing adjustments in 2015. At September 30, 2014, the Company determined that the Pressure Sensitive Materials business met the criteria to be classified as a discontinued operation, which required retrospective application to certain financial information for all periods presented. The assets and liabilities of the Pressure Sensitive Materials business were reflected as held for sale in the consolidated balance sheet at September 30, 2014.
	The following table summarizes the results of the Pressure Sensitive Materials business, reclassified as discontinued operations for the twelve month periods ended December 31, 2014, 2013, and 2012:
		Twelve Months Ended

	(Loss) income from discontinued operations includes the operating results of our Pressure Sensitive Materials business, goodwill impairment charges, direct transaction costs associated with the divestiture, and plant closure costs associated with the Stow, Ohio plant.
	Assets and liabilities classified as held for sale are required to be recorded at the lower of carrying value or fair value less costs to sell. Accordingly, the Company recorded goodwill impairment charges of $44.7 million in the third quarter of 2014 when it became apparent the business would sell for less than its carrying value. There were no indicators of impairment prior to the third quarter of 2014.
	In March 2014, the Company announced the closure of its plant in Stow, Ohio, one of its Pressure Sensitive Materials manufacturing facilities. Operations ceased at this location in May 2014. During the twelve months ended December 31, 2014, plant closure costs of $25.0 million were recorded and approximately $20.8 million of cash payments were made. These costs are included within (loss) income from discontinued operation and included a final withdrawal payment for a multi-employer pension plan.

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, accounts receivable, accounts payable, short-term borrowings, and long-term debt.  At December 31, 2014 and 2013, 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, 2014 and 2013 follow:
		31-Dec-14					31-Dec-13
		Carrying		Fair Value			Carrying		Fair Value

	Total long-term debt	$	1,315.90	$	1,410.90		$	1,421.40	$	1,520.10
	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. The fair value of the Company's derivatives follow:

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 major Western European currencies for the Company’s European operations, the U.S. dollar for the Company’s Brazilian operations, and the U.S. and Australian dollars for the Company’s New Zealand and Australian operations.  The Company has not designated these derivative instruments as hedging instruments.  At December 31, 2014, and 2013, the Company had outstanding forward exchange contracts with notional amounts aggregating $2.3 and $5.5 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 were 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, 2014 and 2013 are presented in the table below:

	The Company recorded an impairment at September 30, 2014 to adjust the Pressure Sensitive Materials net assets to fair value less costs to sell. The Company completed its annual impairment tests in the fourth quarter of 2014 with no other indications of impairment of goodwill found.  The Company does not have any accumulated impairment losses.

	Total defined benefit, defined contribution, and multiemployer plan pension expense in 2014, 2013, and 2012 was $37.2 million, $53.2 million, and $68.7 million, respectively.
	The Company sponsors a 401(k) savings plan (a defined contribution plan) for substantially all U.S. employees.  Through December 31, 2013, the Company contributed $0.50 for every pre-tax $1.00 an employee contributed on the first two percent of eligible compensation plus $0.25 for every pre-tax $1.00 an employee contributed on the next six percent of eligible compensation for the plans that include a company match.  Effective January 1, 2014 the Company contributes $0.50 for every pre-tax $1.00 an employee contributes on the first four percent of eligible compensation plus $0.25 for every pre-tax $1.00 an employee contributes on the next four percent of eligible compensation for the plans that include a company match. The Company contributions are invested in Company stock and are fully vested after three years of service.  Total Company contributions for 2014, 2013, and 2012 were $10.6 million, $9.0 million, and $8.9 million, respectively.
	Effective January 1, 2006, the Company’s U.S. defined benefit pension plans were amended for approximately two-thirds of the participant population, and effective January 1, 2014, two of the Company's three U.S. defined benefit plans were frozen. Further benefit accruals for all persons entitled to benefits under these two plans were frozen as of December 31, 2013. The Company recorded a plan curtailment of $32.6 million related to the amendments, and the actuarial gain recorded in 2013 was also impacted by the freeze. (Refer to the "Change in Benefit Obligation Table".) For those employees impacted, future pension benefits were replaced with the Bemis Investment Profit Sharing Plan (BIPSP), a defined contribution plan which is subject to achievement of certain financial performance goals of the Company.  Total contribution expense for BIPSP and other defined contribution plans (including a multiemployer defined contribution plan) was $16.5 million in 2014, $18.9 million in 2013, and $10.7 million in 2012.  Defined benefit multiemployer plans covered employees at two manufacturing locations and provided for contributions to union administered defined benefit pension plans during the year. One of the plans covered employees at a facility that was closed during the year. Amounts contributed to the multiemployer plans in 2014, 2013, and 2012 totaled $0.7 million, $1.0 million, and $1.3 million, respectively.
	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 October 2014, the Society of Actuaries released final reports of new mortality tables and a mortality improvement scale for measurement of retirement program obligations in the U.S. The Company has adopted these tables in measuring defined benefit plan liabilities in 2014. In addition, the Company also sponsors an unfunded supplemental retirement plan to provide senior management with benefits in excess of limits under the federal tax law and increased benefits to reflect a service adjustment factor.
	Net periodic pension cost for defined benefit plans included the following components for the years ended December 31, 2014, 2013, and 2012:

	Net periodic pension cost	$	9.4			$	24.3			$	47.8
	In 2012, the Company recognized a $12.7 million pension settlement charge related to its supplemental pension plan. The supplemental pension plan provides for a lump sum payment option at the time of retirement. The Company recognizes pension settlements when payments exceed the sum of service and interest cost components of net periodic pension cost of the plan for the fiscal year.

The Company’s general funding policy is to make contributions as required by applicable regulations and when beneficial to the Company for tax purposes.  The employer contributions for the years ended December 31, 2014 and 2013, were $10.8 million and $39.0 million, respectively.  Total expected cash contributions for 2015 are $3.3 million which are expected to satisfy plan and regulatory funding requirements.
For the years ended December 31, 2014 and 2013, the U.S. pension plans represented approximately 92 percent and 90 percent, respectively, of the Company’s total plan assets and approximately 92 percent and 88 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
	2014			2013			2014			2013
Weighted-average discount rate	4	%		5	%		3.67	%		4.25	%
Rate of increase in future compensation levels	—			3.75	%		3.66	%		3.91	%
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
	2014			2013			2012			2014		2013			2012
Weighted-average discount rate	4.89	%		4.13	%		4.25	%		4.25	%	3.89	%		4.68	%

Rate of increase in future compensation levels	—			3.75	%		4.25	%		3.93	%	3.79	%		3.81	%
The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid:

The Pension Investment Committee appointed by the Company’s Board of Directors 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 65 percent in fixed income securities and approximately 35 percent in equity securities. Equity securities primarily include investments in diversified portfolios of domestic 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 2015 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.

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, 2014 and 2013 follows:

	The Company sponsors several defined postretirement benefit plans that cover a majority of salaried and a portion of nonunion hourly employees.  These plans provide healthcare benefits and, in some instances, provide life insurance benefits.  Postretirement health care plans are contributory, with retiree contributions adjusted annually.  Further benefit accruals for all persons entitled to benefits under these plans were frozen as of March 31, 2014. The Company recorded a plan curtailment gain of $3.0 million related to the amendments. Life insurance plans are noncontributory.

	The employer contributions for the years ended December 31, 2014 and 2013 were $0.5 million and $0.4 million, respectively.  The expected contribution for 2015 is $0.5 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 7.5 percent for 2014 and 7.0 percent for 2013; the health care trend was reset from 6.5 percent to 7.5 percent in 2014, remaining at 7.5 percent in 2015, grading to 5 percent in 2025 (reducing 0.25 percent annually), and remains 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 2014 and the post retirement benefit obligations at December 31, 2014.
	The Company’s actuarial valuation date is December 31.  The weighted-average discount rates used to determine the actuarial present value of the net postretirement projected benefit obligation for the years ended December 31, 2014 and 2013 were 4.00 percent and 5.00 percent, respectively.  The weighted-average discount rates used to determine the net postretirement benefit cost was 4.62 percent, 4.00 percent, and 4.25 percent for the years ended December 31, 2014, 2013, and 2012, respectively.

MULTIEMPLOYER DEFINED BENEFIT PENSION PLANS

As of December 31, 2014, the Company contributes to one multiemployer defined benefit pension plan under the terms contained in a collective bargaining agreement.  The risks of participating in multiemployer plans are different from single-employer plans in the following aspects:

a.

Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.

b.

If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers.

c.

If the Company chooses to stop participating in a multiemployer plan, the Company may be required to pay that plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

The Company settled and paid a withdrawal liability for the withdrawal from the Central States Southeast and Southwest Areas Pension Fund as part of a Pressure Sensitive Materials plant closure (refer to Note 6 - Divestiture). The Company recorded charges related to the withdrawal from the GCIU - Employer Retirement Fund as part of its facility consolidation consolidation activities in the years ended December 31, 2013, 2012, and 2011. In December 2013, the Company settled with the GCIU and paid the withdrawal liability in full.

The Company’s participation in these plans for the annual periods ended December 31, 2014, 2013, and 2012 is outlined in the table below.

Share-based Compensation Arrangement by Share-based Payment Award [Line Items]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	STOCK INCENTIVE PLANS
	In 2014, the Company adopted the 2014 Stock Incentive Plan, which replaced the 2007 Stock Incentive Plan. The 2014 Stock Incentive Plan provides for the issuance of up to 3,282,170 shares of common stock to certain employees and other service providers. The number of shares available under the 2014 Stock Incentive Plan represented the number of shares that were remaining available for issuance under the 2007 Stock Incentive Plan when the new plan was adopted as no further awards would be made under the prior plan. As of December 31, 2014, 3,324,257 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 or the 2007 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 not less than three years, nor more than six years, from the date of the stock award grant to an employee.  Stock awards for directors vest immediately.  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 $14.0 million in 2014, $15.9 million in 2013, and $16.8 million in 2012. As of December 31, 2014, the unrecorded compensation cost for stock awards was $21.7 million and will be recognized over the remaining vesting period for each grant which ranges between 2015 and 2017.  The remaining weighted-average life of all stock awards outstanding as of December 31, 2014 was 1.21 years.  These awards are considered equity-based awards and are therefore classified as a component of additional paid-in capital.
	In addition, cash payments are made during the vesting period on the outstanding stock awards granted prior to January 1, 2010, equal to the dividend on the Company’s common stock.  Cash payments equal to dividends on awards made on or after January 1, 2010, will be 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, 2014, 2013 and 2012 was $40.65, $33.75, and $30.61, respectively.
	Performance-Based Stock Awards
	Certain officers and key employees are also eligible to receive 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 shareowner 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, 2014, 2013 and 2012 was $46.42, $36.98, and $39.10, respectively, which the Company determined using a Monte Carlo simulation and the following assumptions:
		2014		2013			2012
	Average risk-free interest rate	0.76	%	0.37	%		0.4	%
	Expected volatility (Bemis Company, Inc.)	19.7	%	21.9	%		27.7	%
	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 2015, there was a 59.5 percent payout of 2012 awards, and the balance was canceled. In 2014, there was no payout of 2011 awards and they all were canceled. During 2013, there was a 54.7 percent payout of 2010 performance grants, and the balance were canceled.
	The following table summarizes stock awards unit activity for the year ended December 31, 2014:

	Commercial paper has been classified as long-term debt to the extent of available long-term backup credit agreements, in accordance with the Company’s intent and ability to refinance such obligations on a long-term basis.  The weighted-average interest rate of commercial paper outstanding at December 31, 2014, was 0.5 percent.  The maximum amount of commercial paper outstanding during 2014 was $491.0 million, and the average outstanding during 2014 was $323.9 million.  The weighted-average interest rate during 2014 was 0.3 percent.
	As of December 31, 2014, the Company had available from its banks a $1.1 billion revolving credit facility.  This credit facility is used principally as back-up for the Company’s commercial paper program and expires on August 12, 2018.  The revolving credit facility is supported by a group of major U.S. and international banks.  Covenants imposed by the revolving credit facility include limits on the sale of businesses, minimum net worth calculations, and a maximum ratio of debt to total capitalization.  The revolving credit agreement includes a combined $100 million multicurrency limit to support the financing needs of the Company’s international subsidiaries.
	Public notes totaling $400 million matured in August 2014. On July 15, 2014, the Company further amended its revolving credit facility to provide for a $200 million term loan. This term loan has an eight-year term and a variable rate based on the one-month London Interbank Offered Rate (LIBOR) plus a fixed spread. The Company used this term loan combined with commercial paper borrowings to refinance the $400 million public notes which matured in August 2014.
	Refer to Note 8 - Derivative Instruments for information regarding the interest rate swap.
	Long-term debt maturing in 2015 is $317.3 million. These amounts have been classified as long term liabilities in accordance with the Company’s ability and intent to refinance such obligations on a long term basis. There is no long-term debt maturing from 2016-2018.  Long-term debt maturing in 2019 is $399.4 million. The Company was in compliance with all debt covenants throughout 2014.

	In 2014 various foreign subsidiaries paid $170.0 million of dividends to the U.S. parent. These dividends, in addition to the divestiture of the Pressure Sensitive Materials business, resulted in an increase in the foreign tax credit carryover of $8.0 million. The Company placed a full valuation allowance against these credits.
	In 2013 a Brazilian subsidiary paid $21.3 million of dividends out of current earnings to the U.S. parent. This resulted in $8.9 million of additional tax and an increase in the foreign tax credit of $8.0 million. The Company placed a full valuation allowance against these credits. The net increase in tax due to the dividends was largely offset by the release of various foreign valuation allowances and foreign deferred tax liabilities.
	As of December 31, 2014, the Company had foreign net operating loss carryovers of approximately $72.1 million that are available to offset future taxable income.  Approximately $28.5 million of the carryover expires over the period 2015-2033.  The remaining balance has no expiration.  In addition, the Company had $25.0 million of foreign tax credit carryover that is available to offset future tax.  This carryover expires over the period 2018-2024.
	Current authoritative guidance issued by the Financial Accounting Standards Board ("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 Company’s management determined that a valuation allowance of $47.9 million and $42.1 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, 2014 and 2013, respectively.
	Provision has not been made for U.S. or additional foreign taxes on $203.7 million of undistributed earnings of foreign subsidiaries because those earnings are considered to be indefinitely reinvested in the operations of those subsidiaries.  It is not practical to estimate the amount of tax that might be payable on the eventual remittance of such earnings.
	The Company had total unrecognized tax benefits of $24.1 million and $21.4 million for the years ended December 31, 2014 and 2013, respectively. The approximate amount of unrecognized tax benefits that would impact the effective income tax rate if recognized in any future periods was $24.1 million and $21.4 million for the years ended December 31, 2014 and 2013, respectively.
	A reconciliation of the beginning and ending amount of unrecognized tax benefits, in millions, is as follows:
		2014			2013
	Balance at beginning of year	$	21.4		$	25.6
	Additions based on tax positions related to the current year	2.3			3.6
	Additions for tax positions of prior years	3.2			5.1
	Reductions for tax positions of prior years	(0.6		)	(9.9		)
	Reductions due to a lapse of the statute of limitations	(1.7		)	(2.9		)
	Settlements	(0.5		)	(0.1		)
Balance at end of year	$	24.1		$	21.4
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, $1.0 million of net tax benefit, and $0.6 million of net tax expense related to interest and penalties during the years ended December 31, 2014, 2013, and 2012, respectively. The Company had approximately $6.1 million and $6.5 million accrued for interest and penalties, net of tax benefits, at December 31, 2014 and 2013, respectively.
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 $7.0 million 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 2012 have been audited and settled.  With few exceptions, the Company is no longer subject to examinations by tax authorities for years prior to 2009 in the significant jurisdictions in which it operates.

Accumulated Other Comprehensive Income (Loss)	12 Months Ended

Stockholders' Equity Note [Abstract]
Accumulated Other Comprehensive Income (Loss)	ACCUMULATED OTHER COMPREHENSIVE LOSS
	On January 1, 2013, the Company adopted changes required by the FASB to the reporting of amounts reclassified out of accumulated other comprehensive loss. These changes require an entity to report the effect of significant reclassifications out of accumulated other comprehensive loss on the respective line items in net income if the amount being reclassified is required to be reclassified in its entirety to net income. For other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures that provide additional detail about those amounts. Other than the additional disclosure requirements (see below), the adoption of these changes had no impact on the Consolidated Financial Statements. The components and activity of accumulated other comprehensive loss are as follows:
	(in millions)	Foreign Currency Translation			Pension And Other Postretirement Liability Adjustment			Accumulated Other Comprehensive Loss

	December 31, 2014	$	(151.3	)	$	(140.4	)	$	(291.7	)
	Accumulated other comprehensive loss associated with pension and other postretirement liability adjustments are net of tax effects of $85.9 million and $55.6 million as of December 31, 2014 and 2013, respectively. Reclassifications of $15.8 million ($9.3 million, net of tax) and $25.5 million ($15.6 million, net of tax) for the years ended December 31, 2014 and 2013, respectively, related to pension costs. Other comprehensive income before reclassifications of $7.7 million ($4.8 million, net of tax) for the year ended December 31, 2014, related to remeasurement of other postretirement plans triggered by curtailment. An additional reclassification of $2.2 million ($1.4 million, net of tax) for the year ended December 31, 2014, related to curtailment benefits associated with other postretirement plans. Refer to Note 10 — Pension Plans for additional detail.
	In September 2013 the Company approved amendments related to multiple qualified defined benefit pension plans effective December 31, 2013. The amendments froze all further benefit accruals for all persons entitled to benefits under the plans as of December 31, 2013. As a result, final average pay formulas will not reflect future compensation increases or additional service after December 31, 2013. Other comprehensive income before reclassifications reflects the effect of these plan amendments.

Earnings Per Share [Abstract]
Earnings Per Share Computations	EARNINGS PER SHARE COMPUTATIONS
	The Company considers unvested share-based payment awards that contain nonforfeitable rights to receive dividends or dividend equivalents (whether paid or unpaid) to be participating securities, and thus includes them in the two-class method of computing earnings per share. Participating securities include a portion of the Company’s unvested employee stock awards, which receive nonforfeitable cash payments equal to the dividend on the Company’s common stock. The calculation of earnings per share for common stock shown below excludes the income attributable to the participating securities from the numerator and excludes the dilutive impact of those awards from the denominator.

	Certain stock awards outstanding were not included in the computation of diluted earnings per share above because they would not have had a dilutive effect.  The excluded stock awards represented an aggregate of 0.3 million shares at December 31, 2014 and 2013.  There were no anti-dilutive stock awards outstanding at December 31, 2012.

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 17 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 has accrued an amount that it believes to be adequate to cover its exposure.
	São Paulo Tax Dispute
	Two of the Company’s subsidiaries (Dixie Toga Ltda ("Dixie Toga") and Itap Bemis Ltda) were involved in a tax dispute with the City of São Paulo, Brazil ("City"). The City imposes a tax on the rendering of printing services. The City assessed this city services tax on the production and sale of printed labels and packaging products. The Company disagreed and contended that the city services tax was not applicable to its products and that the products were subject only to the state value added tax ("VAT"). Under Brazilian law, state VAT and city services tax are mutually exclusive and the same transaction can be subject to only one of those taxes. Based on a ruling from the State of São Paulo, advice from legal counsel, and long standing business practice, the Company appealed the city services tax and instead continued to collect and pay only the state VAT.
	The City disagreed and assessed the subsidiaries the city services tax for the multiple years dating back to 1991. The Company challenged the assessments and ultimately litigated the issue. Multiple courts, including the Lower Tax Court in the city of São Paulo and the São Paulo Court of Justice, previously issued decisions in favor of the Company. In May 2014, the Second Panel of the Supreme Court for the State of São Paulo issued a decision in favor of the Company in one of the relevant lawsuits.  The City did not appeal, and the decision is final.  The Company is involved in several similar lawsuits with the City. We expect it may take several years before the remaining cases are fully decided, but we believe this decision has established precedent and should lead to a favorable ruling in the remaining cases.
	Brazil Tax Dispute - Goodwill Amortization
	During October 2013, Dixie Toga 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 $14.3 million, translated to U.S. dollars at the December 31, 2014 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. The Company intends to litigate the matter if it is not resolved at the administrative appeal levels. The ultimate outcome will not be determined until the Brazilian tax appeal process is complete, which 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 Investigation
	On September 18, 2007, the Secretariat of Economic Law ("SDE"), a governmental agency in Brazil now integrated into the CADE (Brazilian Competition Commission) Superintendence General after a change in the law, initiated an investigation into possible anti-competitive practices in the Brazilian flexible packaging industry against a number of Brazilian companies including a Dixie Toga subsidiary.  The investigation relates to periods prior to the Company’s acquisition of control of Dixie Toga and its subsidiaries.  Given the nature of the proceedings, the Company is unable at the present time to predict the outcome of this matter.

Segment Reporting [Abstract]
Segments of Business	SEGMENTS OF BUSINESS
	The Company's business activities are organized around and aggregated into its two principal business segments, U.S. Packaging and Global 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. Minor intersegment sales 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 general corporate expense, interest expense, other non-operating income, and income taxes.
	Products produced within the U.S. and Global Packaging business segments service packaging applications for markets such as food, medical devices, personal care, agribusiness, chemicals, pet food, and consumer products.
	A summary of the Company’s business activities reported by its two business segments follows:

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
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 $1.7 million, $3.1 million, and $2.6 million in 2014, 2013, and 2012, respectively, included in other operating income on the accompanying consolidated statement of income.  Investments in joint ventures of $8.0 million and $7.7 million as of December 31, 2014 and 2013, respectively, are included in deferred charges and other assets on the accompanying consolidated balance sheet.
	In connection with the implementation of an enterprise resource planning system during 2012, the Company recorded adjustments primarily to cost of goods sold during the fourth quarter in order to align the application of certain accounting practices among the business segments. These adjustments substantially offset one another in the Company's consolidated financial statements. The $2.1 million consolidated expense is disaggregated by reportable segment in Note 20.
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 $3.5 million, $2.6 million, and $1.7 million in 2014, 2013, and 2012, respectively, are included as a component of other operating income.  There were no foreign currency transaction losses recorded within non-operating income in 2014, 2013 or 2012.
Revenue Recognition, Policy [Policy Text Block]	Revenue recognition:  Sales and related costs of products sold are recognized when persuasive evidence of an arrangement exists, title and risk of ownership have been transferred to the customer, the sales price is fixed or determinable, and collectability is reasonably assured.  These conditions are typically fulfilled upon shipment of products.  All costs associated with revenue, including customer rebates and provisions for estimates of sales returns and allowances, are recognized as a deduction from revenue in the period in which the associated revenue is recorded. Customer rebates are accrued using sales data and rebate percentages specific to each customer agreement. Shipping and handling costs are classified as a component of cost of products sold while amounts billed to customers for shipping and handling are classified as a component of sales. The Company accrues for estimated warranty costs when specific issues are identified and the amounts are determinable and also considers the history of actual claims paid. Taxes assessed by governmental authorities on revenue producing transactions, including sales, value added, excise and use taxes, are recorded on a net basis (excluded from revenue).
Environmental Costs, Policy [Policy Text Block]	Environmental cost:  The Company is involved in 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, 2014 and 2013 was $6.1 million and $7.6 million, respectively.  The Company made a favorable adjustment of $0.8 million in 2014 based on current estimates of liability. The Company made no other adjustments to the reserve accounts and costs which were directly expensed for environmental remediation matters resulted in charges to the income statements for each of the years 2014, 2013, and 2012.  There were no third party reimbursements for any of the years presented.
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]	Facility consolidation and other costs:  Facility consolidation and other 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 facility consolidation 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 facility consolidation 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 facility consolidation costs, including costs to relocate equipment, are generally recorded as 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]	Accounts receivable:  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 accounts receivable.  Accounts receivable are presented net of an allowance for doubtful accounts of $21.0 million and $30.7 million at December 31, 2014 and 2013, respectively.
	The Company enters into supply chain financing programs from time to time to sell accounts receivables without recourse to third-party financial institutions.  Sales of accounts receivable are reflected as a reduction of accounts receivable 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 the year ended December 31, 2014, the Company sold without recourse accounts receivable representing approximately five percent of net sales, and the associated discount on sale of accounts receivables was insignificant.
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 market.  Inventory values using the FIFO method of accounting approximate replacement cost.  Inventories are summarized at December 31, as follows:
	(in millions)	2014		2013
	Raw materials and supplies	$	193.9	$	215.6
	Work in process and finished goods	381.9		432.9
	Total inventories	$	575.8	$	648.5
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, 3-16 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 $154.6 million, $162.2 million, and $175.5 million for 2014, 2013, and 2012, 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 income.  Interest costs, which are capitalized during the construction of major capital projects, totaled $0.2 million in 2014, $0.3 million in 2013, and $0.1 million in 2012.
	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 $69.9 million and $74.3 million as of December 31, 2014 and 2013, 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 business combinations.  Goodwill is not amortized, but instead tested annually or when events and circumstances indicate an impairment may have occurred. The Company's reporting units each contain 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, of which two are included in the Global Packaging reportable segment. The other reporting unit is the U.S. Packaging segment.
	Goodwill for the reporting units is reviewed for impairment annually in the fourth quarter of each year using a two-step process. In the first step, the fair value of each reporting unit is compared to its carrying value, including goodwill. The determination of the estimated fair value of the reporting units utilizes both a discounted cash flow valuation and a market multiple method. Significant inputs to the discounted cash flow valuation method include discount rates, long-term sales growth rates and forecasted operating margins. The market multiple method estimates fair value by comparing the Company to similar public companies. If the fair value exceeds the carrying value, step two is not required and an impairment loss is not recognized. If step two were required, the implied fair value of goodwill would be calculated by deducting the fair value of all tangible and intangible net assets, including unrecognized intangible assets, of the reporting unit from the fair value of the reporting unit. If the implied fair value of goodwill is less than the carrying value of goodwill, an impairment loss would be recognized equal to the difference.
	Current 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 two-step impairment test. The Company applied the Step 0 assessment to the U.S. Packaging reporting unit in 2014 and 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 two-step goodwill impairment test for this reporting unit was not necessary in 2014.
	The annual impairment test indicated no impairment for the years ended December 31, 2014, 2013, or 2012, nor does the Company have any accumulated impairment losses.
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.  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 $102.4 million and $54.7 million at December 31, 2014 and 2013, 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 2014, the Company purchased 3.8 million shares of common stock in the open market for $152.1 million. During 2013, the Company purchased 2.0 million shares of common stock in the open market for $77.3 million.  The Company did not purchase any shares of common stock during 2012.  At December 31, 2014, approximately 6.7 million common shares can be repurchased, at management’s discretion, under authority granted by the Company’s Board of Directors in 2014.

	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.
