Abstract
(EN)
The invention provides a polyolefin composition comprising: (i) 55 to 95 wt% of a propylene butene random copolymer having an MFR2 of 1.0 to 20.0g/10 min, a butene content of 1.5 to 8.0 wt% and prepared using a single site catalyst; and (ii) to 45 wt% of an ethylene based plastomer having a density of 860 to 905 kg/m3, an MFR2 of 0.3 to 30 g/10 min and prepared using a single site catalyst.
