Abstract

A polymer mixture comprises at least 40 but less than 85% by weight of an ethylene copolymer (A) which has a density of from 0.91 to 0.93 g/cm3, an HLMFR (190° C./21.6 kg) of from 5 to 60 g/10 min and a molar mass distribution Mw/Mn≦3, and more than 15 but at most 60% by weight of an ethylene copolymer (B) which has a density of from 0.93 to 0.945 g/cm3, an HLMFR (190° C./21.6 kg) of from 8 to 20 g/10 min and a molar mass distribution Mw/Mn≧7, where the percentages by weight are in each case based on the total mass of the components (A) and (B).
