The invention relates to a physically mixed propylene polymer composition comprising the following three components: A) 100 parts by weight of crystalline polypropylene containing 0-10 mol-% of ethylene and/or another α-olefin, B) 1-30 parts by weight of a random propylene/ethylene copolymer, composed of 30-85 mol-% of propylene; this copolymer contains 0-10 mol-% of a diene component and has i) a micro-isotacticity of at least 0.8 and ii) contains 0-10 wt-% of a material that does not dissolve in boiling n-cyclohexane, and C) 0-30 parts by weight of polyethylene containing 0-15 mol-% of an α-olefin, where components A) and B) form a physical mixture with each other. |
