Claim:
1. A polyethylene composition comprising copolymers of ethylene with C 3 -C 20 1-alkenes, or mixtures of ethylene homopolymers and copolymers of ethylene with C 3 -C 20 1-alkenes, wherein the polyethylene composition has a molar mass distribution width (MWD) M w /M n of from 7 to 15, a density of from 0.942 to 0.954 g/cm 3 , determined according to ISO 1183 at 23° C., a weight average molar mass M w of from 20,000 g/mol to 500,000 g/mol, a MIE of from 1.0 to 3.0 g/10 min, a MIF of from 100 to 200 g/10 min, and a ratio MIF/MIE of from 40 to 50, where MIE is the melt flow rate at 190° C. with a load of 2.16 kg and MIF is the melt flow rate at 190° C. with a load of 21.6 kg, both determined according to ISO 1133.
