1. A multilayer film comprising:
(a) one layer (a) based on
at least one propylene copolymer in an amount of at least 15% by weight,
at least one propylene homopolymer in an amount of at least 40% by weight, and
optionally up to 30% by weight of additives, based in each case on the total weight of the layer (a), the components always adding up to 100% by weight,
(b) one multi-ply, inner layer (b) based on at least one homo- and/or copolyamide having isophoronediamine units as a polyamide component,
(c) one layer (c) based on
at least one propylene copolymer in an amount of at least 15% by weight,
at least one propylene homopolymer in an amount of at least 40% by weight, and
optionally up to 30% by weight of additives, based in each case on the total weight of the layer (c), the components always adding up to 100% by weight, and
(d) one adhesion-promoter layer (d) arranged between the layer (a) and the layer (b), based on at least one modified thermoplastic olefin homo- or copolymer,
(e) one adhesion-promoter layer (e) arranged between the layer (b) and the layer (c), based on at least one modified thermoplastic olefin homo- or copolymer, the thickness of the multi-ply layer (b) being at least 40% of the total thickness of the multilayer film.
