Abstract:
A pouch containing a flowable material, said pouch being made from a film structure with at least one seal layer of a polymeric composition consisting essentially of:(a) from 10 to 100 percent, based on the total weight of said composition, of a mixture of (1) from 5 to 95 percent by weight, based on 100 weight parts of said mixture, of a linear ethylene copolymer interpolymerized from ethylene and at least one alpha-olefin in the range of C.sub.3 -C.sub.18 and having a density from 0.916 to 0.940 g/cm.sup.3 and a melt index of less than 10 g/10 minutes, and a molecular weight distribution, Mw/Mn, ratio of greater than 4.0, and a peak melting point greater than 100.degree. C. as measured by a differential scanning colorimeter, and (2) from 5 to 95 percent by weight, based on 100 weight parts of said mixture, of a high pressure low density polyethylene having a density from 0.916 to 0.930 g/cm.sup.3, a melt index of less than 1 g/10 minutes and melt strength greater than 10 cN as determined using a Gottfert Rheotens unit at 190.degree. C.; and(b) from 0 to 90 percent, based on the total weight of said composition, of an ethylene-vinyl acetate copolymer having a weight ratio of ethylene to vinyl acetate from 2.2:1 to 24:1 and a melt index of from 0.2 to 10 g/10 minutes.
