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.
