Insulating microwave interactive packaging

摘要

The combination of insulating material with microwave interactive food packaging for enhanced cooking properties is disclosed. An insulating microwave packaging material ( 200 ) and a method of making the same are also disclosed. In one embodiment, the insulating microwave packaging material ( 200 ) is formed by bonding a microwave interactive material substrate ( 205 ) that creates sensible heat upon exposure to microwave energy to a second substrate ( 210 ) along bond lines ( 212 ) arranged in a pattern to form closed cells ( 214 ). Upon impingement of the insulating microwave packaging material ( 200 ) by microwave energy in a microwave oven, the closed cells ( 214 ) expand to form insulating pockets ( 216 ). One side of the insulating pocket ( 216 ) bulges and lofts above the opposite side. When a food product is situated on the insulating microwave packaging material ( 200 ), the insulating pockets ( 216 ) insulate the food product from the microwave oven environment.
