A package, for example, a freezable microwavable package containing a food product, has a sealing film that includes a vent system that is scored into the package.

Packages with vent systems

A hermetically sealed package, for example a freezable microwavable package containing a food product, has a sealing film that includes a vent system that is scored by a laser into the package.

Hermetic packages with laser scored vent systems

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.

Vented steam cooking package

A package includes a container formed to include an interior region and a mouth opening into the interior region and a closure coupled to the container to close the mouth. The closure is made from a film coupled to a brim included in the container.

Closure for container

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.

Microwavable frozen food package

A steam-ventable package includes a container formed to include an interior region and a mouth opening into the interior region and a closure coupled to the container to close the mouth. The closure is made from a peelable film coupled to a brim included in the container and configured to be removed from the brim in response to application of shear force applied to the peelable film.

Peelable closure for container

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.

Freezable/microwavable packaging films and venting packages

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.

A multi-layer freezable/microwaveable film having both low temperature resistance and high temperature resistant to withstand subzero freezer storage temperatures and microwave cooking temperatures. The freezable/microwaveable film includes a three-layer coextruded film having a polypropylene/alpha-olefin copolymer inner, heat sealable layer, an adjacent polypropylene or high density polyethylene core layer, and an outer polyethylene skin layer adjacent the core layer opposite the heat sealable layer, and further includes an outer protective layer laminated to the outer skin layer.
