Abstract
It is provided a polymer composition including at least the following components A) 40 to 94 wt.-% based on the overall weight of the polymer composition of a polymer blend, including a1) 50 to 95 wt.-% of polypropylene; a2) 5 to 50 wt.-% of polyethylene; C) 3 to 30 wt.-% based on the overall weight of the polymer composition of a compatibilizer being a copolymer of propylene and 1-hexene, including b1) 30 to 70 wt.-% of a first random copolymer of propylene and 1-hexene; and b2) 30 to 70 wt.-% of a second random copolymer of propylene and 1-hexene having a higher 1-hexene content than the first random propylene copolymer b1); 3 to 30 wt.-% of a modifier selected from the group consisting of plastomers, heterophasic polypropylene copolymers different from component B) and mixtures thereof; with the provisos that the weight proportions of components a1) and a2) add up to 100 wt.-%; the weight proportions of components b1) and b2) add up to 100 wt.-%; the weight proportions of components A), B) and C) add up to 100 wt.-%; component A) has a MFR(230° C., 2.16 kg) determined according to ISO 1133 in the range from 1.0 to 50.0 g/10 min; and component B) has a 1-hexene content in the range from 2.0 to 8.0 wt.-%.
