Abstract

Packaging containers produced from a composite shaped by cold-forming, the term “packaging containers” including base or lid parts or base or lid parts shaped by cold-forming. The base or lid parts can be shaped by cold-forming, and a lid foil or base foil, respectively, can form the corresponding closure for the packaging container. In addition, both the base and the lid part can be shaped by cold-forming, the depressions formed in the base and lid parts advantageously lying opposite one another. Examples of these packaging containers are strip packing or blister packaging for pharmaceutical products. The composite from which the packaging container or parts thereof are produced has a layered structure, for example, comprising: (a) a plastics foil between 10 μm and 250 μm thick; (b) a bi- or monoaxially oriented foil selected from the group comprising polyvinylchloride foils, polyolefin foils, polyamide foils or polyester foils between 10 and 100 μm thick, or a bi- or monoaxially oriented plastics foil composite comprising two foils selected from the group comprising polyvinylchloride foils, polyolefin foils, polyamide foils or polyester foils each between 10 and 50 μm thick; (c) a metal foil between 20 and 200 μm thick; and (a1) a plastics foil between 10 and 250 μm thick. The packaging containers are characterized by a high degree of flatness and/or rigidity.

A packaging container comprising a cold formed composite, the cold formed composite has a layered structure consisting essentially of in sequential order:

(a) a plastic film having a thickness of 10 to 250 μm;
(b) a biaxially or uniaxially stretched film of the polyvinylchloride, polyolefin, polyamide or polyester having a thickness of 10 to 100 μm, or a biaxially or uniaxially stretched plastic laminate of two films of the polyvinylchloride, polyolefin, polyamide, or polyester with each film having a thickness of 10 to 50 μm;
(c) a metal foil having a thickness of 20 to 200 μm;
(d) a biaxially or uniaxially stretched film of the polyvinylchloride, polyolefin, polyamide or polyester having a thickness of 10 to 100 μm, or a biaxially or uniaxially stretched plastic laminate of two films of the polyvinylchloride, polyolefin, polyamide, or polyester with each film having a thickness of 10 to 50 μm;
