ABSTRACT:
A microwave insert for use in an outer microwave transparent carton for surface heating an object, such as a food product, in a microwave oven. The insert includes a flexible layer of interactive material for converting microwave energy into heat, and a support material, preferably a semi-rigid microwave transparent material such as paperboard, for supporting the interactive material in a position adjacent one portion of the surface of the object in a configuration to minimize the amount of overlaps of interactive material. The overlap is provided along a base panel spaced from the folds which define the base panel and is restricted to a zone wherein the overlap zone is positioned to utilize the maximum possible amount of microwave shielding by the object when the object and the insert are located in operative position within a microwave oven.
