Abstract
In one embodiment, an insulating microwave packaging material () includes a microwave interactive material substrate () joined to a second substrate () along bond lines () to define 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.
