<p>The invention concerns packaging containers produced from a composite shaped by cold-forming, the term "packaging containers" including base or lid parts or base and 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 .mu.m and 250 .mu.m 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 .mu.m thick, or a bi- or mononaxially 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 .mu.m thick; c) a metal foil between 20 and 200 .mu.m thick; and a1) a plastics foil between 10 and 250 .mu.m thick. The packaging containers are characterized by a high degree of flatness and/or rigidity.</p> |
