ABSTRACT:
Multilayer freezable/microwaveable films and packages having both low temperature resistance to withstand subzero freezer storage temperatures and high temperature resistance to withstand microwave cooking temperatures. The freezable/microwaveable films and packages include, for example, a film having at least three coextruded layers comprising an inner heat sealable layer, at least one core layer adjacent to the heat sealable layer, and an outer skin layer adjacent the core layer opposite the heat sealable layer. Preferably, the films and packages further include an outer protective layer laminated to the outer skin layer. The freezable/microwaveable packages can include a venting system, such as vent slits or a vent valve in the package, or vents in at least one seal of the package, to facilitate microwave heating or cooking of the package contents.
