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 method of manufacturing a foil for enclosing or wrapping a product configured to be heated in an oven includes: providing an aluminium layer, applying a first ink material at a surface of the aluminium layer to form a first ink layer, and applying a second ink material at a surface of the first ink layer to form a second ink layer. The first ink layer is positioned between the aluminium layer and the second ink layer, and is configured to absorb radiant energy. The second ink layer is configured to allow radiant energy to pass through to reach the first ink layer. A binder system of the first ink material or the second ink material is based at least in part on polyvinyl butyral (PVB).

A biodegradable microwave susceptor and constructs incorporating the susceptor are disclosed for heating a food item in a microwave oven. The biodegradable microwave susceptor includes a patterned susceptor layer of metal on a biodegradable substrate. Selected areas of the susceptor layer may be demetallized to remove susceptor material. The susceptor may be incorporated into a construct for containing or supporting a food item to be heated.

A container for holding a food product. The container can comprise a base layer and a liner at least partially attached to an inner surface of the base layer, a flange comprising a central panel of the base layer, an opening extending in the central panel, and a sidewall comprising at least a panel foldably connected to the central panel along the opening.

A retortable package includes a body defining a perimeter and a peripheral seal formed along the perimeter of the body. The peripheral seal includes at least one peripheral self-venting region and at least one peripheral non-venting region. The retortable package further includes an intermediate seal formed within the perimeter of the body and contiguous with the peripheral seal. The intermediate seal divides the body into two compartments. The compartments receive respective products therein. Upon heating of the products, the intermediate seal ruptures before the at least one peripheral self-venting region ruptures. Further, the at least one peripheral self-venting region ruptures before the at least one peripheral non-venting region ruptures.

A microwave popcorn bag for containing and heating popcorn kernels in a microwave oven. The bag is constructed of a laminated fibrous material and comprises a base panel, top panel, side panels, and interior space. The side panels have gussets with fold areas and fold lines that are adjacent to the base panel and that enable the bag to expand. An oil-resistant microwave susceptor film is laminated with the fibrous material and extends laterally across the base panel and the fold lines into the fold areas. Microwave interactive material is confined to the base panel. As the popcorn is heated, the bag expands and the microwave susceptor film forms a tray structure that collects oil and resists it penetrating through the fibrous material.

A tray for holding one or more food products includes a plurality of panels including a central panel, a plurality of compartment flaps foldably connected to a respective panel of the plurality of panels, and a plurality of end flaps foldably connected to a respective panel of the plurality of panels, the plurality of compartment flaps and the plurality of end flaps are overlapped to form a plurality of compartments of the tray.

The present invention provides packages pre-packed with nuts/seeds for roasting thereof in a microwave.

An embodiment of the present disclosure a food package article with metal nanoparticles. The metal nanoparticles may absorb microwave radiation and converts microwave radiation into heat.
