Blends of high molecular weight polybutylene with low density polyethylene

摘要

A composition having peel seal characteristics is disclosed, which comprises (i) from 8 to 49 % by weight of a homopolymer or copolymer of but-1-ene having an average molecular weight of at least 500,000 and (ii) from 92 to 51 % by weight of a modified or non-modified low density polyethylene having a density of 930 kg m-3 or less. Films and sheets comprising this composition are also disclosed, as are laminates including such films and sheets.
