Реферат: The invention relates to a sheetlike composite comprising, as layers of a layer sequence in the direction from an outer face of the sheetlike composite to an inner face of the sheetlike composite, a) a first polymer layer, b) a carrier layer, and c) a barrier layer, wherein the first polymer layer is characterized by a ratio of a proportion of aromatic groups in the first polymer layer to a proportion of carbonyl groups in the first polymer layer in a range from 0.18 to 0.34. The invention further relates to processes for producing a sheetlike composite, a container precursor and a closed container and to the aforementioned process products; to a further container precursor; to a further closed container; and to uses of the sheetlike composite, of a hardener and of a printing ink.
Sheetlike composite, in particular for the production of dimensionally stable foodstuff containers, having a first colour application and a second colour application with a 2d-code
