Abstract
The invention provides that receptor material sheet is so formed or treated as to vary the microwave heating characteristics thereof. In one arrangement, the microwave heating characteristic is varied by corrugating the receptor material, while in another case the sheet material is embossed or treated so as to break up the receptor layer. In preferred arrangements the above two features are embodied in the same material, and according to a further preferred feature the receptor materials are embodied in packages for foodstuffs to be microwave cooked.
