Abstract:
A multilayer film made from or containing at least one core layer made from or containing a polypropylene composition made from or containing: A) from 95 wt % to 60 wt %; of a propylene homopolymer having a fraction insoluble in xylene at 25° C. greater than 90 wt %, based upon the total weight of the propylene homopolymer; and B) from 5 wt % to 40 wt %; of an heterophasic propylene ethylene copolymer, the sum of the amounts of A) and B) being 100.
