Abstract
A package configured to receive a food item for storage and heating therein is disclosed. The package includes an opening and a closure mechanism and comprises an insulating microwave material. A plurality of packages in a stacked relation also is provided.
Claims25
A package for heating, browning, and/or crisping a food item in a microwave oven, comprising:
- a pair of panels adjoined in an opposed, facing relationship to define a cavity and an open end, wherein the panels are formed at least partially from a microwave energy interactive insulating material including
- a microwave energy interactive material supported on a first polymer film layer,
- a moisture-containing layer joined to the microwave energy interactive material, and
- a second polymer film layer joined to the moisture-containing layer in a predetermined pattern, thereby forming a plurality of closed cells between the moisture-containing layer and the second polymer film layer;
- and
- a closure mechanism proximate the open end, wherein the closure mechanism is selected from the group consisting of a zipper and a slider.
A package for heating, browning, and/or crisping a food item in a microwave oven, comprising:
- a first panel and a second panel adjoined in an opposed, facing relationship to define a cavity and an opening, wherein the first panel and the second panel are each formed at least partially from a microwave energy interactive insulating material including
- a microwave energy interactive material supported on a first polymer film layer,
- a moisture-containing layer joined to the microwave energy interactive material, and
- a second polymer film layer joined to the moisture-containing layer in a predetermined pattern, thereby forming a plurality of closed cells between the moisture-containing layer and the second polymer film layer;
- and
- a closure mechanism proximate the opening, wherein the closure mechanism comprises a tab that communicates with a corresponding slot in the first panel.
A package for heating, browning, and/or crisping a food item in a microwave oven, comprising:
- a pair of panels adjoined in an opposed, facing relationship to define a cavity, an interior surface, and an open end;
- and
- an adhesive material overlying the interior surface of at least one of the panels proximate the open end,
- wherein the panels are formed at least partially from a microwave energy interactive insulating material including
- a microwave energy interactive material supported on a first polymer film layer,
- a moisture-containing layer joined to the microwave energy interactive material, and
- a second polymer film layer joined to the moisture-containing layer in a predetermined pattern, thereby forming a plurality of closed cells between the moisture-containing layer and the second polymer film layer, wherein the closed cells are adapted to inflate in response to microwave energy.
