Closed container, in particular a foodstuff container, having a shaping coefficient
The invention relates to a closed container, delimiting an interior from an exterior, wherein the closed container comprises a sheetlike composite; wherein the sheetlike composite comprises a layer sequence, comprising as mutually superposed layers in a direction from an. inner face of the sheetlike composite to an outer face of the sheetlike composite a) an inner polymer layer, b) a barrier layer, and c) a carrier layer; wherein the closed container is characterised by a shaping coefficient, determined according to the method described herein, in the range from 1.0 to 10.0 m 2 /kg. Further, the invention relates to a method by which a closed container with a shaping coefficient is obtainable; to the closed container obtainable by this method; to an apparatus, designed for producing one of the afore¬ mentioned closed containers; to a use of a sheetlike composite for producing one of the afore¬ mentioned closed containers; and to a use of one of the aforementioned closed containers for storing a foodstuff.
1. A closed container, delimiting an interior from an exterior, wherein the closed container comprises a sheetlike composite;
