ABSTRACT:
Pouches containing a flowable material e.g. milk, ice cream, are made of a sealant film which is from about 50 to 100 parts by weight of a linear copolymer of ethylene and a C.sub.6 -C.sub.10 .alpha.-olefin, and from 0 to 50 parts by weight of at least one polymer selected from linear copolymer of ethylene and a C.sub.4 -C.sub.10 .alpha.-olefin, and a high-pressure polyethylene. The sealant film is selected on the basis of providing (a) pouches with an M-test value substantially better, at the same film thickness, than that obtained with pouches made with film of a specified blend of an ethylene-butene copolymer and a high pressure polyethylene, or (b) an M(2)-test value of less than about 12%, for pouches having a volume of from greater than 1.3 to 5 liters, or (c) an M(1.3)-test value of less than about 5% for pouches having a volume of from 0.1 to 1.3 liters. The M, M(2) and M(1.3)-tests are defined pouch drop tests. The pouches may also be made from composite films in which the sealant film forms at least the inner layer.
