Abstract:
1. A process for the production of a container that delimits a container interior from the surroundings and that is formed at least in part from a sheet-like composite, comprising the process steps: (I) providing a sheet-like composite on a roll; (II) forming the container from the sheet-like composite from the roll; and (III) closing the container; wherein the sheet-like composite comprises: wherein the sheet-like composite is obtained on a roll by a process comprising the process steps: (a) providing a composite precursor containing at least the carrier layer; (b) applying the adhesive layer and the polymer inner layer by laminating extrusion to the composite precursor; and (c) rolling up the sheet-like composite on the roll; wherein at least the polymer inner layer, at least the adhesive layer, or at least both are stretched during the application to produce a stretched polymer layer, wherein the carrier layer has a hole that is covered at least with the barrier layer, the adhesive layer and the polymer inner layer as hole-covering layers, and wherein at least one of the hole-covering layers comprising a stretched polymer layer is subjected to heat treatment.
