Abstract
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.
