摘要:
A precursor composite material (60) is provided, having a layer sequence (50) comprising an adhesive layer (20), a carrier layer (10) on the adhesive layer (20), a release layer (40) on the carrier layer (10) and a parting layer (30) on the release layer (40), wherein the layer sequence (50) is arranged in such a way that the side of the adhesive layer (20) facing away from the layer sequence (50) is arranged at least in sub-regions on the side of the parting layer (30) facing away from the layer sequence (50). Further provided are a composite material, a method for producing the precursor composite material, a method for producing the composite material and a use of the precursor composite material and of the composite material.
摘要:
The present invention relates to a multilayer film comprising a layer (a) and a layer (c), in each case based on at least one propylene copolymer in an amount of at least 15% by weight, at least one propylene polymer in an amount of at least 40% by weight, in each case based on the total weight of the layer (a)/(c), at least one multi-ply inner layer (b) based on at least one homo- and/or copolyamide comprising isophoronediamine units as a polyamide component, adhesion promoter layers (d) and (e), wherein the thickness of the multi-ply layer (b) is at least 40% of the total thickness of the multilayer film, preferably at least 45% or at least 50%.
