Abstract: A multilayer film made from or containing a core layer made from or containing a polypropylene composition made from or containing:
A) from 90 wt % to 50 wt %; of a propylene homopolymer; and
B) from 10 wt % to 50 wt %; of a propylene ethylene copolymer having: i) xylene soluble fraction at 25° C. ranging from 14 wt % to 27 wt %; ii) intrinsic viscosity of the fraction soluble in xylene at 25° C. ranging from 1.0 to 2.4 dl/g; iii) melt flow rate ranging from 1.0 g/10 min to 4.0 g/10 min; iv) an ethylene content ranging from 5.0 wt % to 12.0 wt %; v) the ethylene derived units content on the fraction insoluble in xylene at 25° C. ranging from 2.5 wt % to 6.0 wt %; vi) the ethylene derived units content on the fraction soluble in xylene at 25° C. ranging from 15.2. wt % to 30.2 wt %, the sum of A) and B) being 100 wt %.
