Abstract

The present invention relates to a method comprising as method steps: a) providing a sheetlike composite precursor comprising a carrier layer; b) overlaying the sheetlike composite precursor on an outer face of the sheetlike composite precursor with a liquid first polymer composition; c) hardening the liquid first polymer composition, thereby obtaining a first polymer layer; and d) overlaying the sheetlike composite precursor on the outer face of the sheetlike composite precursor with a liquid second polymer composition; wherein the first polymer layer in method step d) comprises an isocyanate content in a range from 0.1% to 50% by weight, based on the weight of the first polymer layer. The invention further relates to a sheetlike composite obtainable by the method; a container precursor and a closed container, each comprising the sheetlike composite; and to uses of a liquid primer and the sheetlike composite.
