摘要

Sheet metal, polyurethane adhesive layer, polypropylene copolymer plastic foil composites are disclosed. The adhesive layer is made from a solvent-containing, two component polyurethane adhesive. The polypropylene copolymer plastic foil is essentially or totally composed of statistical polypropylene copolymer produced by statistic copolymerisation of 1 to 8 % by weight ethylene and/or other alpha -monoolefines, with the exception of propylene, and 99 to 92 % by weight propylene, in relation to the total weight of the monomer composition. The polypropylene copolymer has a molar mass distribution MW : Mn in a range from 2 to 8 and a melt flow index MFI 230 DEG C/2.16 kg in a range from 5 to 10 g/10 min.
