The invention relates to a polyethylene composition with multimodal molecular mass distribution, which has density in the range of from 0.949 to 0.955 g/cm3 at 23 °C and an MFI190/5 in the range of from 0.1 to 0.3 dg/min, and which comprises from 38 to 45 % by weight of a low-molecular-mass ethylene homopolymer A, from 30 to 40 % by weight of a high-molecular-mass copolymer B made from ethylene and from another 1-olefin having from 4 to 8 carbon atoms, and from 18 to 26 % by weight of an ultrahigh-molecular-mass ethylene copolymer C,wherein all of the percentage data are based on the total weight of the molding composition.
