Thermoformable multilayer film for the protection of substrates and objects obtained

摘要

The present invention relates to a thermoformable multilayer film comprising in succession: a protective layer (A); a transparent layer (B) comprising (by weight the total amount being 100%) 0 to 100% of a fluoropolymer (Bl) and 100 to 0% of a polymer (B2) essentially consisting of alkyl (meth)acrylate units; a layer (C) based on a polyamide with amine terminal groups; a layer (D) consisting of a polyolefin functionalized by an unsaturated carboxylic acid anhydride; a bonding layer (E) made of a polyolefin. This film is obtained by coextruding the various layers and is then used to cover various substrates, for example by injection-moulding the substrate in the melt onto the multilayer film placed in the bottom of an injection mould, the layer (A) of the film being placed against the wall of the mould.
