Abstract

A polyethylene composition comprising a base resin comprising (A) 70 to 30 wt.-% of a polyethylene homo- or copolymer fraction with respect to the total weight of the base resin having a density determined according to ISO 1183-1:2004 (method A) of 955 to 980 kg/m³ and a MFR₂ determined according to ISO 1133 at 190 °C and a load of 2.16 kg of 50 to 600 g/10 min; (B) 30 to 70 wt.-% of a polyethylene homo- or copolymer fraction with respect to the total weight of the base resin having a density determined according to ISO 1183-1:2004 (method A) of 947 to 970 kg/m³ and a MFR₂ determined according to ISO 1133 at 190 °C and a load of 2.16 kg of 0.0001 to 1.0 g/10 min; wherein the average molecular weight of fraction (A) is lower than the average molecular weight of the base resin; and wherein the sum of the amounts of fraction (A) and fraction (B) is 100 wt.-% with respect to the total weight of the base resin.
