A multilayer film made from or containing a skin layer (A) and a core layer (B), wherein: the skin layer (A) is made from or containing a polyolefin composition (I) made from or containing:
(a) from 70% to 95% by weight of a propylene copolymer, having up to and including 10.0% by weight of units deriving from an alpha-olefin and from 10% to 20% by weight of a fraction soluble in xylene at 25 C.; and (b) from 5% to 30% by weight of a butene-1 polymer,
wherein the amounts of (a) and (b) are based on the total weight of (a)+(b); and the core layer (B) is made from or containing a copolymer of propylene with up to and including 25% by weight of an alpha-olefin.
