    摘要: The use in the manufacture of a polyethylene article of a polyethylene composition comprising 20 to 50% wt of a copolymer of ethylene and a C3-20 alpha olefin comonomer and 50 to 80% wt. Of a lower weight average molecular weight ethylene polymer, the polyethylenes of the composition together having a density of 935 to 965 kg/m3, weight average molecular weight of 60000 to 300000 g/mol, an MFR2.16 at 190° C. of 0.1 to 10 g/10 min., and a molecular weight distribution (MWD) of from 2.5 to 20, the copolymer having a comonomer content of from 0.006 to 9 mol % and a degree of branching of 0.03 to 45 branches per 1000 carbons, and the ethylene polymer having a density of 939 to 975 kg/m3 and a weight average molecular weight of 20000 to 200000 g/mol.
