Abstract

The present invention refers to a sheetlike composite (100), comprising as a layer sequence in a direction from an outer surface (101) of the sheetlike composite (100) to an inner surface (102) of the sheetlike composite (100)a) an outer polymer layer (103),b) a colour application (104),c) a carrier layer (105), andd) a barrier layer (107);wherein the outer polymer layer (103) is characterised by a density in a range from 919 to 925 kg/m³. The invention further refers to a container precursor (500) and to a container (700), in each case comprising at least part of the preceding sheetlike composite (100); to processes (300, 400, 600) for preparing a sheetlike composite (100), a container precursor (500), and a closed container (700); to the preceding products; and to uses of the sheetlike composite (100), and of a polyolefin.
