A method of heating food and a construct for use therein

摘要

In a method of heating food in a microwave oven, a carton having a bottom panel (120) with a susceptor (132) of optimized effectiveness mounted thereon is provided, food (123) and the carton are placed on the dish-shaped turntable tray of the microwave oven with the food supported by the susceptor, and the microwave oven is operated so that the microwave interactive material (125) of the susceptor becomes hot, the tray is heated by the hot layer of microwave interactive material so that peak thermally induced stresses occur in the tray at locations proximate of beveled corners (128) of the microwave interactive material, the peak thermally induced stresses being less than a predetermined amount in response to the corners of the microwave interactive material being beveled.
