Abstract: A polyethylene composition made from or containing:



A) from 85% to 99% by weight of an ethylene polymer composition made from or containing:

AI) from 80 to 95% by weight of an ethylene polymer component, having a density DI from 952 to 965 kg/m3 and a MIF of from 10 to 35 g/10 min.; and
AII) from 5 to 20% by weight of an ethylene polymer component, having a density DII from 940 to 950 kg/m3 and a MIF value lower than the MIF value of AI);
wherein the amounts of AI) and AII) are referred to the total weight of AI)+AII); and


B) from 1% to 15% by weight of a butene-1 polymer component.
