A propylene composition comprising (percent by weight): A) 60%-95%, of a crystalline propylene copolymer containing from 2.0% to 10.0% of ethylene derived units having a melting point ranging from 148° C. to 160° C.; wherein the melting temperature Tm is measured by DSC on the as-reactor polymer; B) 40%-5%, of a copolymer of ethylene containing from 70% to 85%, of ethylene derived units intrinsic viscosity ranging from 0.8 to 3 dl/g. |
