US Classification:

219730, 219732, 219734, 426107, 426234, 99DIG 14

Abstract:

The combination of insulating material with microwave interactive food packaging for enhanced cooking properties is disclosed. An insulating microwave packaging material () and a method of making the same are also disclosed. In one embodiment, the insulating microwave packaging material () is formed by bonding a microwave interactive material substrate () that creates sensible heat upon exposure to microwave energy to a second substrate () along bond lines () arranged in a pattern to form closed cells (). Upon impingement of the insulating microwave packaging material () by microwave energy in a microwave oven, the closed cells () expand to form insulating pockets (). One side of the insulating pocket () bulges and lofts above the opposite side. When a food product is situated on the insulating microwave packaging material (), the insulating pockets () insulate the food product from the microwave oven environment.

US Classification:

219730, 219732, 219762, 426234, 99DIG 14

Abstract:

A microwave energy interactive insulating material is provided. The material may include a susceptor film comprising a microwave energy interactive material supported on a first polymeric film layer, a moisture-containing layer superposed with the microwave energy interactive material, and a second polymeric 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 polymeric film layer. The closed cell is capable of inflating upon exposure to microwave energy.
