Beschreibung
Zusammenfassung:	A multilayered composite structure comprises at least one layer (A) consisting of an ethylene homopolymer or copolymer, at least one layer (B) comprising a barrier material and at least one layer (C) comprising an adhesion promoter material serving to improve the adhesion between these layers, wherein the adhesion promoter material comprises an adhesive polymer composition comprising a) 20 to 95% (w/w) of an ethylene homo- or copolymer which is a copolymer of ethylene with C3-C20-alkene, and b) 5 to 80% (w/w) of a polar copolymer of ethylene with at least one comonomer which comonomer is selected from the group consisting of an acrylate and acrylic acid. The composite structure can be used for fuel containers, especially fuel tanks in automotive vehicles.
