Abstract

A susceptor bag (20) for microwave heating of food products, such as french fries, fish sticks, apple turnovers and burritos, is formed from a single flexible sheet comprising a layer (16, 28) of metal or other electroconductive material having microwave susceptor thickness, supported on a paper substrate material (12, 24). The flexible sheet is folded on itself to form a sleeve (20) which houses and engages the food product. The thin metal layer (16, 28) is provided only in the regions where the food is located. The metal layer (16, 28) usually is overlied by a polymeric film layer (14, 26) or a release coating. By providing the thin metal (16, 28) upon application of microwave energy, the interior of the food product (30) becomes heated to a desired edible temperature while the exterior becomes crispened by thermal energy generated by the thin metal layer.
