SHEETLIKE COMPOSITE, IN PARTICULAR FOR THE PRODUCTION OF DIMENSIONALLY STABLE FOODSTUFF CONTAINERS, HAVING A FIRST BENDING RESISTANCE WHICH IS LESS THAN A FURTHER BENDING RESISTANCE
The present utility model refers to a sheetlike composite, comprising as a layer sequence in a direction from an outer surface of the sheetlike composite to an inner surface of the sheetlike composite a) an outer polymer layer, b) a colour application, c) a carrier layer, and d) a barrier layer; wherein the sheetlike composite comprises at least one longitudinal crease line; wherein the at least one longitudinal crease line is oriented in a first direction; wherein the sheetlike composite has a first bending resistance in the first direction; wherein a further direction is perpendicular to the first direction; wherein the sheetlike composite has a further bending resistance in the further direction; wherein the first bending resistance is less than the further bending resistance. The utility model further refers to a container precursor and to a closed container, in each case comprising the preceding sheetlike composite; and to a container precursor and a closed container, in each case having a sheetlike composite with a first bending resistance along a first direction which is less than a further bending resistance along a further direction.
