ABSTRACT OF THE DISCLOSURE Pouches containing a flowable material e.g. milk, ice cream, are disclosed. The sealant film from which the pouch is made is selected from about 50 to 100 parts by weight of a linear copolymer of ethylene and a C6 - C10 alpha-olefin, and from 0 to 115 parts by weight of at least one polymer selected from a blend comprising linear a copolymer of ethylene and a C4 - C10 alpha-olefin, and a high-pressure polyethylene. The sealant film is selected on the basis of providing 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-1 copolymer and a high pressure polyethylene. The M-test is a defined pouch drop test. The pouches may also be made from composite films in which the sealant film forms at least the inner layer.
