<p>The present invention relates to polypropylene film-adhesion promoter-metal laminates, adhesion promoter used being polypropylene modified with carboxyl groups and/or anhydride groups. Polypropylene random copolymers of 90 to 99% by weight, preferably 93 to 99% by weight, of propylene and 1 to 10% by weight, preferably 1 to 7% by weight, of comonomers, having a molecular weight distribution Mw:Mn in the range from 2 to 10, preferably 3 to 6, and a melt flow index MFI 230 DEG C./2.16 kg in the range of 1 to 20 g/10 min, preferably in the range from 4 to 15 g/10 min, are used for the production of the polypropylene film.</p> |
