A sealable enclosure is disclosed that is configured to enclose an object that is to be heated, wherein heating of the sealable enclosure with the object sealed therein permits gas generated by the heating to vent out through a first micro-pore portion disposed in a fold of film layer. Initially, the generated gas is retained in the sealable enclosure. When the temperature of the strip of heat sensitive adhesive reaches a threshold temperature, the strip of heat sensitive adhesive releases so that fold opens, wherein the gas vents through the micro-pore portion disposed in the film layer out into an ambient region surrounding the sealable enclosure while preventing ambient contaminates in the ambient region from entering into the sealable enclosure.

The present invention is directed to a tray endowed with an improved rigidity and resistance to deformation and bending. The tray comprises a plurality of primary sidewalls and a plurality of chamfered corners having a corner secondary sidewall integrally formed with and extending from the base, wherein the primary sidewalls and corner secondary sidewalls define a product receiving cavity. The tray further includes a plurality of ribs integrally formed with and extending downwardly from the base, and a plurality of channels positioned between and separating adjacent ribs, wherein each channel is substantially perpendicular to a corner secondary side wall.

A methodology and product or system configurations are provided which allow food to be directly irradiated for cooking applications which involve the impingement of direct radiant energy on food or comestible items. Cooking vessels or cook-packs are used that are optically transmissive in visible or infrared narrow wavelength bands emitted in suitable narrowband cooking or heating systems.

A closable cooking pouch includes a heat resistant pouch body with a flap attached to it. The flap is tuckable into an opening the permits access to the pouch's interior. To close the pouch, the flap is tucked into the pouch's interior and a hook portion that forms part of the flap is inserted through a slot on the pouch body. Once through the slot, the hook portion retains at least a portion of the flap in the slot when the pouch is closed and typically provides sufficient retaining force to keep the pouch closed if it is flipped while being used for cooking. The pouch may be manufactured from a single sheet of material.

The rancidity of prepackaged foodstuffs, such as nuts, is inhibited by packaging the foodstuffs in a GRAS plastic material. This enables the nuts to be exposed to continuous heating or heating and cooling cycles such as within a conventional food warmer, exposure to heating lamps or to microwave ovens for extended periods of up to about thirty (30) days while impeding the rancidity of the nut products. Suitable GRAS packaging materials include low density polypropylene, low density polyethylene, PET polyester laminates, and the like. The packaging can be in any geometric form.

Coextruded, biaxially oriented multilayer films comprising a base layer comprising a polyester having an intrinsic viscosity greater than 0.75 dl/g and a heat-sealable layer directly adhered to said base layer, said heat-sealable layer comprising an amorphous polyester having a melting temperature not higher than the melting temperature of the polyester of the base layer and a thermoplastic resin characterized in that the heat-sealable layer comprises a further polyester resin are described. Also packages comprising a container, a food product and the above coextruded, biaxially oriented multilayer film are described. The packages are particularly suitable for ready-meals to be used in conventional oven at high temperatures.

An ovenable cooking apparatus for facilitating the cooking of food components while maintaining the separateness thereof may include a first container for holding a first food component, and a second container for holding a second food component. The separation of the first food component from the second food component maintains the surface area for the first and second food components to facilitate heating of the first and second food components. The first food component may have a liquid based content for producing steam when heated, and one or both of the first container and the second container may define a passage for providing airflow and steam flow for contacting the second container and/or the second foodstuff and heating or steaming the second food component. Additionally, the second container may be steam impermeable for cooking bread and the like.

A packaging or wrapping for a food product, capable of resisting to high temperatures and of eliminating the overpressure generated by the water vapour inside the packaging due to temperature rise, without the same packaging having any aperture communicating its inside and the outside environment. The packaging is also adapted to restrain/reduce the emission of odor-generating substances that are generated during the heating or baking of the packaged food product, with respect to what occurs in the absence of a packaging, or with a packaging provided with apertures.

An ovenable tray composite comprises a polymeric based liner and a fiber based component. The polymeric based liner incorporates polyolefin materials for performance in both adhesion (during use) and separation (for disposal) from the fiber based component, as well as high temperature resistant polymers that allow for the entire tray composite to be ovenable. Packages made from the lined trays described herein can be used for packaging food items intended to be heated for cooking or reheating the contents.

A sealable enclosure is disclosed that is configured to enclose an object that is to be heated, wherein heating of the sealable enclosure with the object sealed therein permits gas generated by the heating to vent out through a first micro-perforation portion disposed in an enclosure, wherein the gas vents into a cavity formed between the outside surface of the enclosure, a lower surface of a file layer, and a strip of heat sensitive adhesive. When the temperature of the strip of heat sensitive adhesive reaches a threshold temperature, the strip of heat sensitive adhesive releases so that the gas may vent from the cavity through a second micro-perforation portion disposed in the film layer out into an ambient region surrounding the sealable enclosure while preventing ambient contaminates in the ambient region from entering into the sealable enclosure.
