<p>The present invention relates to a thermoformable film in the form of a composite (multilayer, laminate) film which contains an upper film containing certain amounts by weight of a) at least one crosslinked PP-EPDM and b) an uncrosslinked propylene block copolymer or heterophase propylene block polymer, where from 15 to 1% by weight of b) has been replaced by equal amounts by weight of a polymer and/or ionomer c) containing reactive groups. The invention furthermore relates to the process for the preparation of the composite film, and to the use thereof. The lower film or films contain certain amounts by weight of d) at least one partially crosslinked EPDM, e) a propylene homopolymer, copolymer or graft polymer, f) at least one polymer and/or ionomer containing reactive groups, and g) at least one polymeric crosslinking agent containing reactive groups.</p> |
