Multilayer film comprising a polyolefin composition

A multilayer film comprises:

• at least one layer comprising
• a polyolefin composition comprising
• A) 5-30% by weight, based upon the total weight of the polyolefin composition, of a propylene homopolymer or a propylene ethylene copolymer containing 90% by weight or more of propylene units;
• component (A) containing 10% by weight or less of a fraction soluble in xylene at 25° C. (XSA), both the amount of propylene units and of the fraction XSA being referred to the weight of (A);
• B) 20-50% by weight, based upon the total weight of the polyolefin composition, of a copolymer of ethylene and a C3-C8 alpha-olefin containing from 0.1% to 20% by weight of alpha-olefin units and containing 25% by weight or less;
• of a fraction soluble in xylene at 25° C. (XSB), both the amount of alpha-olefin units and of the fraction XSB being referred to the weight of (B);
• and
• C) 30-60% by weight, based upon the total weight of the polyolefin composition, of a copolymer of ethylene and propylene containing from 25% to 75% by weight of ethylene units and containing from 40% to 95% by weight of a fraction soluble in xylene at 25° C. (XSC), both the amount of ethylene units and of the fraction XSC being referred to the weight of (C);
• wherein the amounts of (A), (B) and (C) being referred to the total weight of (A)+(B)+(C), the sum of the amount of (A)+(B)+(C) being 100.
