Abstract: A hermetically sealed package, for example a freezable, microwavable package containing a food product, having a sealing film that includes a vent system that is scored by a laser into the package. The vent system includes at least one linear or non-linear vent pattern scored into a portion of the outer surface of the sealing film so as to form at least one weakened wall pattern. According to certain embodiments, the vent pattern may be scored by a laser to a depth that does not perforate the sealing film. The inner surface of the sealing film that is adjacent to the weakened wall pattern is directly exposed to pressure that is generated in the inner region of the package during heating. According to some embodiments, the vent pattern may have a vent pattern span that is approximately 1% to 50% of the size of the inner region span.

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 including 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.

Abstract: A container includes a sleeve, a first end closure, and a second end closure. The first end closure closes off a first end of the sleeve and the second end closes off an opposite second end of the sleeve. The sleeve and end closures cooperate to define an interior region therebetween that receives products therein.

Abstract: A vented steam cooking package includes a container formed to include an interior region and a steam-venting system. The steam-venting system is formed in the package to vent steam from the interior region to atmosphere surrounding the package during heating.

Abstract: A film is mated with a paper to form a space therebetween. The film is made of plastics material. Separation of the paper from the film can provide access to an article stored in the space provided between the paper and the film.

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.

Abstract: The present invention provides a multilayer sealable film having a sealable outer layer, a first heat resistant layer, a core layer, and a second heat resistant layer. In a preferred embodiment of the present invention, the core layer is positioned between the two heat resistant layers. The sealable layer is positioned such that one of the heat resistant layers is located between the seal layer and the core layers.

Abstract: A lap sealable film for forming bags on conventional vertical form/fill/seal equipment containing a seal layer and a barrier layer. The seal layer and barrier layer form opposing surfaces of the film. The seal layer contains single site catalyzed polyethylene and is capable of sealing to the barrier layer. The barrier layer comprises a heat resistant and moisture barrier material, such as high density polyethylene or polypropylene.

Abstract: A shipping container for lidded, chimed cans designed to avoid "chime ride" and consequent damage to the can bodies is achieved by reverse folding the major and minor flaps forming the bottom wall and top wall of a regular slotted container and providing a one-piece corrugated pad between the bottom surface of the chimed cans and the inner surface of the bottom wall to form a rigid platform for the cans.
