What is claimed is: 1. A package for receiving a food item for storage and heating therein, the package comprising: a first panel and a second panel joined along respective substantially opposed edges to define a sleeve having at least one open end; and at least one closure mechanism for closing the open end, wherein at least a portion of the first panel and at least a portion of the second panel is formed from a microwave energy interactive insulating material including a microwave energy interactive material supported on a first polymer film layer, a moisture-containing layer superposed with the microwave energy interactive material, and a second polymer film layer joined to the moisture-containing layer in a predetermined pattern, thereby forming at least one closed cell between the moisture-containing layer and the second polymer film layer. 2. The package of claim 1, further comprising at least one vent to permit the passage of water vapor from the sleeve. 3. The package of claim 1, further comprising an interior surface on which the food item is placed, wherein the interior surface proximate the open end includes an adhesive material covering at least a portion thereof. 4. The package of claim 1, wherein the closure mechanism comprises a flap extending from the open end of the sleeve, wherein the flap is adapted to be inserted into the open end. 5. The package of claim 1, wherein the closure mechanism comprises a flap extending from the open end of the sleeve, wherein the flap includes a mechanism for releasably sealing the sleeve. 6. The package of claim 5, wherein the mechanism for releasably sealing the sleeve comprises an adhesive material covering at least a portion of the flap. 7. The package of claim 6, wherein the flap is adapted to be folded over the open end such that the adhesive contacts an exterior surface of the sleeve. 8. A plurality of sleeves according to claim 1, stacked in a face-to-face relation. 9. The plurality of sleeves of claim 8 in a carton, the carton comprising an open portion through which the sleeves may be removed or dispensed. 10. A package for storing and heating a food item, comprising: a plurality of adjoined panels at least partially defining a cavity, the plurality of panels including a pair of opposed panels, wherein each of the opposed panels comprises 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 patterned configuration, thereby forming a plurality of closed cells between the moisture-containing layer and the second polymer film layer. 11. The package of claim 10, wherein the microwave energy interactive material comprises aluminum, indium tin oxide, or any combination thereof. 12. The package of claim 10, wherein at least some of the closed cells inflate in response to thermal energy. 13. The package of claim 10, wherein at least a portion of the microwave energy interactive insulating material expands in response to microwave energy. 14. The package of claim 10, further comprising an opening dimensioned to accommodate the food item. 15. The package of claim 10, including a mechanism for closing the opening. 16. A storage, browning, and/or crisping pouch comprising; a plurality of panels joined along respective edges to define a cavity having at least one open end for passing a food item therethrough, the plurality of panels including a first panel and a second panel in an opposed relation, wherein each of the first panel and the second panel is at least partially formed from a microwave energy interactive insulating material including a first polymer film superposed with a moisture-containing layer, a layer of metal disposed between the first polymer film and the moisture-containing layer, and a second polymer film joined to the moisture-containing layer in a predefined pattern, thereby forming a plurality of closed microwave energy interactive insulating cells between the moisture-containing layer and the second polymer film; and a closure mechanism for substantially sealing the open end. 17. The storage, browning, and/or crisping pouch of claim 16, wherein the layer of metal comprises aluminum, indium tin oxide, or any combination thereof. 18. The storage, browning, and/or crisping pouch of claim 16, wherein the closure mechanism comprises a flap extending from the open end of the pouch, wherein the flap is adapted to be inserted into the open end. 19. The storage, browning, and/or crisping pouch of claim 16, wherein the closure mechanism comprises a flap extending from the open end of the pouch, wherein the flap includes a mechanism for releasably sealing the pouch. 20. The storage, browning, and/or crisping pouch of claim 19, wherein the mechanism for releasably scaling the pouch comprises an adhesive material covering at least a portion of the flap. 21. A plurality of pouches according to claim 16, stacked in a face-to-face relation. 22. The plurality of pouches of claim 21 in a carton, the carton comprising an open portion through which the pouches may be removed or dispensed.
