摘要
The invention relates to a sheet-like composite, comprising as layers of a layer sequence: a) an outer polymer layer, b) a carrying layer following the outer polymer layer, c) a barrier layer following the carrying layer, d) an adhesion-promoting layer following the barrier layer, and e) an inner polymer layer following the adhesion-promoting layer; wherein the adhesion-promoting layer comprises an outer surface of the adhesion-promoting layer and an inner surface of the adhesion-promoting layer; wherein the outer surface of the adhesion-promoting layer i) is adjacent to the barrier layer, and ii) is characterised by a first C═O group absorption maximum; wherein the inner surface of the adhesion-promoting layer A) is adjacent to the inner polymer layer, B) is characterised by a second C═O group absorption maximum, and C) has a first distance to the outer surface of the adhesion-promoting layer; wherein the first C═O group absorption maximum is higher than the second C═O group absorption maximum. The invention further relates to a process for manufacturing a sheet-like composite; a sheet-like composite, obtainable by the process; a container precursor; a process for producing a container precursor; a container precursor obtainable by the process; a container; a process for producing a container; a container obtainable by the process; a use of the sheet-like composite; and a use of the container.
