摘要：
The invention relates to a novel polyolefin composition which is suitable for producing drawn tapes, fibres and filaments which have improved mechanical properties. The composition comprises A) 2 30 wt % of a propylene copolymer which comprises a a) random propylene copolymer having a content of ethylene and/or C 4-C 8a-olefin of 0.5 to 12 wt % and optionally an b) ethylene-a-olefin rubber, B) 70 98 wt % of a high density polyethylene having a density of 930 to 965 kg/m3 and a MFR (190° C./2.16 kg) of 0.3 to 20 g/10 min.
