A food package and method of controlling heating of a foodstuff within the food package using microwave energy wherein the food package has a microwave shielding layer containing a plurality of apertures therein sized to permit penetration of evanescent microwave energy into the interior of the package with the microwave shielding layer being moved outward as the package expands due to generation of water vapor such that an interior volume of the package is subsequently protected against substantial microwave irradiation of the foodstuff upon and beyond completion of the microwave heating cycle.

[ What is claimed is:] [1.]1. A food package for controlling heating with microwave energy comprising:a. a microwave shielding layer with a plurality of apertures therein prior to exposure to microwave energy, with the apertures sized to permit substantially evanescent penetration of microwave energy into an interior of the package during microwave heating;b. a foodstuff contained in the food package with the foodstuff initially located in close proximity to the microwave shielding layer; andc. means for moving the microwave shielding layer away from close proximity to the foodstuff after the package and the foodstuff is irradiated with microwave energy h that the evanescent penetration of the microwave energy is insufficient to over heat the foodstuff when the microwave shielding layer is moved out of close proximity to the foodstuff.
