A packaging device allowing for the distribution, storage and cooking of various food products, such as perishable or frozen food product(s). The packaging device includes a plurality of micro-perforations that may promote the extended shelf-life of the perishable food product and the maintenance of the quality of the perishable food product or be configured to maintain the integrity of a frozen food product. The packaging device also includes a venting system that allows the cooking of the perishable or frozen food products within the packaging device.

The present invention may be used for self-heating edible fluids without an external heating source, and no or minimal leakage or spilling. It may consist of a fully sealed container body that prevents the leakage or mixing of an activation substance and edible fluid. A body inside of the container may behave as conductive wall separating the activation substance and edible fluid to prevent mixing. The invention includes a chemical pack tool that may be punctured into the container and seal the punctured hole so the is no leakage. As the exothermic reaction takes place, a built-in vent or existing one-way valves/vents may be used to prevent excess pressure build up, and then pushed back in to fully seal the container again when it is no longer needed.

An assembly may include a shelf-stable pouch for fruits or vegetables. The assembly may comprise a pouch having a closed condition and an open configuration. The dosed configuration may be configured to seal portions of at least one of the fruits and vegetables and brine prior to heating the pouch for pasteurization. The open condition may allow for the removal and serving of the portions after pasteurization from heating,

To provide a microwave pouch that favorably prevents both of hole formation of the pouch and spurting of contents, with a simple structure. A microwave pouch (10) includes a self-venting mechanism (20). The self-venting mechanism (20) has an annular venting seal (30), a steam release part (40) surrounded by the venting seal (30), and a movable piece (60) defined by a slit (50) formed in the steam release part (40). The venting seal (30) has a seal peel initiation part (31) where peeling is started by steam generated inside the pouch (10) during heating. The slit (50) includes slit both ends (51), and a slit intermediate part (52) formed to extend from the slit both ends (51) toward a region away from the seal peel initiation part (31) and connecting the slit both ends.

A construct includes at least one panel for supporting a food product, the at least one panel formed from a laminate structure having a base layer, a conductive layer, and a surface film. The construct further includes at least one spacing feature extending downwardly from the at least one panel for supporting the at least one panel a distance above an induction source for attenuating heat transferred to the food product in response to an oscillating magnetic field interacting with the conductive layer of the laminate structure.

A vented sealable bag comprises a container, a two-part seal and a vent. The container has opposing sidewalls and a bottom defining a cavity. The sidewalls form a neck defining an opening opposite the bottom, The sidewalls have an inner surface facing the cavity and an outer surface external to the container and the sidewalls have a thickness. A two-part seal is formed on the inner surface of the sidewalls adjacent the neck. The two-part seal has a hook formed on one sidewall and a clasp formed on an opposite sidewall. The hook and clasp are arranged on the inner surface of the sidewalls to form an airtight seal isolating the cavity from an external environment when the hook is embedded in the clasp but otherwise maintain the opening in the container. A vent is integrally formed in one of the sidewalls. The vent is further comprised of a dimple having a thickness that is thinner than the thickness of the sidewalls. The dimple is concave when viewed from the cavity and has a slit formed at an apex that is closed except when the container is sealed and an internal pressure is created that is higher than an external pressure on the outer surface of the sidewalls.

Described are ovenable or cook-in packages that maintain a hermetic seal. The packages include an information-laden header portion, a product portion that includes the hermetic seal and a line of weakness. The information-laden header portion is removably connected to the product portion by the line of weakness. The hermetic seal is maintained after the information-laden header portion is removed from the product portion.

A tray composite comprises a polymeric based liner including an exterior surface layer, an interior surface layer, and a fiber based component removably affixed to the interior surface layer of the polymeric based liner. A release agent is located between the polymeric based liner and the fiber based component. The polymeric based liner and the fiber based component are manually separable after they have been removably affixed together.
