Abstract
A polyethylene composition is disclosed which comprises from 45 to 55 wt % of an ethylene polymer (A) having a density of at least 968 kg/m3, and from 55 to 45 wt % of an ethylene polymer (B) having a density of 920 to 955 kg/m3, wherein the composition has a density of 952 to 961 kg/m3, a high load melt index HLMI of 18-28 g/10 min, a ratio of HLMI/ML of 80-150, and a melt elastic modulus G′ (G″=3000) of 1200-1600 Pa, where HLMI and ML2 are measured according to ISO1133 at a temperature of 190° C. under loads of 21.6 kg and 2.16 kg respectively.
