Abstract

A film includes at least one layer comprising a blend of a first polymer having a crystalline melting point of at least 260°F, and a density of at least 0.925 grams per cubic centimeter, and a second olefinic polymer comprising an ethylene/alpha-olefin copolymer with a density of less than 0.916 grams per cubic centimeter, wherein the film heat seals at a temperature of at least 180°F. The film can include a core layer including an oxygen barrier; and two outer layers each including a blend of a first polymer having a crystalline melting point of at least 260°F, and a density of at least 0.925 grams per cubic centimeter, and a second olefinic polymer comprising an ethylene/alpha-olefin copolymer with a density of less than 0.916 grams per cubic centimeter, wherein the film heat seals at a temperature of at least 180°F. The film can also include one or more intermediate layers disposed between the core layer and respective outer layers, and one or more adhesive layers disposed between respective intermediate and outer layers. Good heat sealability is obtained.
