A pouch containing a flowable material, said pouch being made from a sealant film in tubular form and having transversely heat-sealed ends, said sealant film being made from a material comprising about 50 to 100 parts of a linear copolymer of ethylene and an octene-1 having a density of from 0.916 to 0.930 g/cm3 and a melt index of 0.3 to 2.0 dg/min, and from 0 to 50 parts by weight of at least one polymer selected from the group consisting of a linear copolymer, of ethylene and a C4-C10 a0.916 to 0.930 g/cm3 and a melt index of from 0.3 to 2.0 dg/min, and a high-pressure polyethylene having a density of from 0.916 to 0.924 g/cm3 and a melt index of from about 1 to 10 dg/min, said sealant film being selected on the basis of providing (a) pouches with an M-test value substantially smaller at the same film thickness, than that of pouches made with film of a blend of 85 parts of a linear ethylene/butene-1 copolymer having a density of about 0.919 g/cm3 and a melt index of about 0.75 dg/min and 15 parts of a high pressure polyethylene having a density of about 0.918 g/cm3 and a melt index of 8.5 dg/min, 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) M(1.3)-test value of less than about 5% for pouches having a volume of from 0.1 to 1.3 liters.
