Abstract
Pouches containing a flowable material e.g. milk, ice cream mix, are made of a sealant film which is a blend of a linear ethylene-C.sub.4 -C.sub.10 .alpha.-olefin copolymer and an ethylene-vinyl acetate copolymer. The ethylene-C.sub.4 -C.sub.10 .alpha.-olefin has a density of 0.916 to 0.930 g/cm.sup.3 and a melt index of from 0.3 to 2.0 dg/min. The ethylene-vinyl acetate copolymer has a weight ratio of ethylene to vinyl acetate from 2.2 to 24 and a melt index of from 0.2 to 10 dg/min. The blend has a ratio of linear ethylene-C.sub.4 -C.sub.10 .alpha.-olefin copolymer to ethylene vinyl acetate copolymer of from 1.2:1 to 9:1.
