Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings	Legal Proceedings 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, or one or more of its affiliates, has been identified as 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 at 12 sites in the United States and one in Brazil, with respect to which the Company's liability has not yet been finalized pursuant to a settlement agreement. In addition, the Company or one or more of its affiliates has been identified as a PRP in several other Superfund sites at which the cleanup of the site has been completed or the Company's liability with respect to the site has been resolved pursuant to a settlement (or both). 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 March 31, 2019 and December 31, 2018 was $0.3 million and is included in other liabilities and deferred credits on the accompanying condensed 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 March 31, 2019 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 condensed 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 condensed consolidated financial statements.
