<p>An article, such as a bag, pouch, or casing, is made from a multilayer film (10) which has: (a) a first layer (12), which is an outer film layer, comprising a polyamide having a melting point of from about 250 °F to 400 °F, the first layer (12) having a thickness of less than about 18 percent, based on a total thickness of the multilayer film; (b) a second layer (14) comprising at least one member selected from the group consisting of polyamide 6, polyamide 9, polyamide 10, polyamide 11, polyamide 12, polyamide 66, polyamide 610, polyamide 612, polyamide 6I, polyamide 6T, polyamide 69, and copolymers thereof, the second layer (14) having a thickness of from about 3 to 30 percent of the total thickness of the multilayer film; and (c) a third layer (16) which serves as an O2-barrier layer and comprises at least one member selected from the group consisting of ethylene/vinyl alcohol copolymer, polyvinylidene chloride, and polyalkylene carbonate. The first layer (12) of the film is sealed to itself. The article is suitable for use as a packaging film to be used for cook-in end use. The film provides the article with enhanced sealing and toughness properties. Also disclosed are a bag comprising this multilayer film, as well as a packaged product comprising this multilayer film.</p> |
