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 MFR2 (230° C.) in the range of 3.0 to 10.0 g/10 min, (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) 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.
Unoriented film comprising at least 70 wt. % of an heterophasic propylene copolymer (RAHECO), said heterophasic propylene copolymer (RAHECO) comprises a matrix (M) being a random propylene copolymer (R-PP) and an elastomeric propylene copolymer (E) dispersed in said matrix (M), wherein the heterophasic propylene copolymer (RAHECO) has:
A heterophasic propylene copolymer (RAHECO) for improving the optical properties of an unoriented film, comprising a matrix (M) being a random propylene copolymer (R-PP) and an elastomeric propylene copolymer (E) dispersed in said matrix (M),
