Abstract

A polyolefin film which includes at least one layer containing polyolefin and cycloolefin polymer (COP), where the cycloolefin polymer is amorphous and has a mean molecular weight M.sub.w in the range from 200 to 100,000, and this mean molecular weight M.sub.w of the cycloolefin polymer is at most 50% of the mean molecular weight M.sub.w of the polyolefin, and the cycloolefin polymer is a homopolymer or a copolymer containing at most 20% by weight of comonomer.
