Abstract
Disclosed is a high abuse-resistance film suitable for making bags and pouches. The film has at least one layer comprising a linear copolymer of ethylene and an alpha-olefin with a density of about 0.935 g/cc or less. The copolymer has a comparatively lower I.sub.10 /I.sub.2 ratio than the corresponding ethylene/alpha-olefin with the same comonomer and essentially the same density and essentially the same melt index at condition 190/2.16.
