Film or sheet comprising at least one layer of a polyolefin composition consisting, in percentage by weight referred to the sum of component (a1 ) and (a2) and (b), of: a1 ) 42-88 wt% of a propylene homopolymer or copolymer of propylene with ethylene and /or one or more C 4 -C 10 α-olefin(s), the said homopolymer or copolymer having a solubility in xylene at room temperature (XSm) equal to or less than 10 wt%; a2) 7-39 wt% of a copolymer of ethylene with propylene and /or one or more C 4 -C 10 α-olefin(s) containing 50-80 wt% of ethylene derived units and having a solubility in xylene at room temperature of 50-80 wt%; and b) 0.5-30 wt%, of a ethylene based copolymer plastomer having a density of not more than 0.910 g/cc and a melt flow rate MFR. Measured at 190°C, 2.16 kg of at least 0.5 g/10 minutes. |
