Patent ID: 8618220

Claim:
A propylene copolymer composition consisting of a propylene homopolymer (A) as a matrix polymer, a propylene copolymer (B) containing 13-25 wt. % calculated with respect to the amount of B of ethylene and optionally, one or more additives, wherein the propylene homopolymer (A) and the propylene copolymer (B) are prepared using a Ziegler-Natta catalyst system, the molecular weight distribution M w /M n of each of propylene homopolymer (A) and propylene copolymer (B) is larger than 3 and the propylene copolymer composition has a transparency higher than 8, wherein the ratio of the melt flow rate of propylene homopolymer (A) to the melt flow rate of propylene copolymer (B) (MFR A /MFR B ) is lower than 50, wherein said propylene copolymer composition has a Melt Flow Rate (MFR) higher than 4 and wherein the Melt Flow Rate (MFR) is measured in accordance with ISO 1133 using a 2.16 kg weight and at a temperature of 230Â° C.
