Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENCIES The Company is involved as a party in lawsuits, claims, regulatory inquiries, or disputes arising in the normal course of its business, the potential costs and liabilities of which cannot be determined at this time. Management does not believe the ultimate outcomes of its legal proceedings are likely to be material to its results of operations, financial position, or cash flows. In addition, the Company has insurance policies that provide coverage to various degrees for potential liabilities arising from legal proceedings. In addition to commitments disclosed elsewhere in the Notes to the Consolidated Financial Statements, the Company has other unconditional purchase obligations that arise in the normal course of business operations. The majority of these obligations are related to the purchase of raw material inventory for the Applied Technology and Engineered Films divisions.
