Bags made from ethylene copolymer films, and films and uses of such copolymers for making such bags

摘要

The invention relates to bags with a heat seal zone formed by a composition comprising an interpolymer of ethylene and an alpha-olefin having an MI of from 1.5 to 4.5 g/10 min, preferably from 1.7 to 3.5 g/10 min, and especially from 1.8 to 2.5 g/10 min and a density of from 0.88 to 0.94 g/10 min, preferably from 0.91 to 0.93, g/cm<3 >and especially from 0.912 to 0.922 g/cm<3 >and a CDBI of at least 50%, preferably at least 55% and especially at least 60%, and less than 20 wt % of LDPE; and to uses of films for making such bags.
