摘要：
Heterophasic propylene copolymer (HECO) comprising
(a) a polymer mixture comprising a matrix being a polypropylene, said polypropylene comprises at least three polypropylene fractions, the at least three polypropylene fractions differ from each other by the melt flow rate and (ii) an elastomeric propylene copolymer dispersed in said matrix, and a plastomeric olefin copolymer dispersed in said polymer mixture,
wherein
the plastomeric olefin copolymer is included in the polymer mixture in an amount of between 1 and 5 wt.-% and the heterophasic propylene copolymer has a melt flow rate of equal or more than 40 g/lOmin.
