<p>The invention concerns packaging container produced from a composite shaped by cold-forming, the term "packaging containers" including base of 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 film or base film, 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. The composite from which the packaging container or parts thereof are produced has a layered structure, for example, comprising: a) a plastics film between 10 mum and 250 mum thick; b) a bi- or monoaxially oriented film selected from the group comprising polyvinylchloride films, polyolefin films, polyamide films or polyester films between 10 and 100 mum thick, or a bi- or monoaxially oriented plastics film composite comprising two films selected from the group comprising polyvinylchloride films, polyolefin films, polyamide films or polyester films each between 10 and 50 mum thick; c) a metal foil between 20 and 200 mum thick; and a1) plastics film between 10 and 250 mum thick. The packaging containers are characterized by a high degree of flatness and/or rigidity.</p> |
