1. A polyethylene composition comprising a base resin comprising:
a low molecular weight ethylene polymer component and a high molecular weight ethylene polymer component, wherein the high molecular weight ethylene polymer component has a higher weight average molecular weight than the low molecular weight ethylene polymer component,
wherein the base resin has a density of at least 958.0 kg/m3,
and the polyethylene composition has a melt flow rate MFR2 (190° C., 2.16 kg) of from 0.50 to 0.80 g/10 min, and a melt flow rate MFR21 (190° C., 21.6 kg) of from 32 to 48 g/10 min and a molecular weight distribution being the ratio of the weight average molecular weight and the number average molecular weight, Mw/Mn, of from 10.0 to 15.0.
