    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%.
