摘要：
A film comprising the following layers: I. a layer based on a polyamide whose monomer units contain an average of at least 8 carbon atoms, II. an immediately adjacent layer composed of a moulding composition comprising a polyamide as in I. and a copolymer having functional groups is used for the production of a composite with a substrate which comprises PA6, PA66, PA6/66 or PPA, giving secure adhesion.
