摘要:
Unoriented film comprising at least 70 wt.-% of an heterophasic propylene copolymer, said heterophasic propylene copolymer comprises a matrix being a random propylene copolymer and an elastomeric propylene copolymer dispersed in said matrix, wherein the heterophasic propylene copolymer has (a) a melt flow rate MFR 2 (230 °C) in the range of 2.0 to 15.0 g/10min, (b) a melting temperature in the range of 130 to 150 °C, (c) a xylene cold soluble content in the range of 25 to 50 wt.-%, (d) a comonomer content in the range of 10.0 to 15.0 wt.-%, wherein further the xylene cold soluble content of the heterophasic propylene copolymer has (e) a comonomer content in the range of 20 to 30 wt.-% and (f) an intrinsic viscosity in the range of 0.8 to below 2.0 dl/g.
