Zusammenfassung:	The present invention provides a food package useful for heating a food product in a microwave oven. The package has a tray with an opening for introducing the food product therein. Once the food has been introduced into the tray, the opening is sealed using a microwave releasable adhesive. The microwave releasable adhesive seal includes a microwave interactive material in close proximity to a heat-releasable resin containing a blowing agent. The microwave interactive material preferably is composed of metallic flakes which become hot when exposed to microwave energy. Consequently, when the package is heated in a microwave oven, the microwave interactive material becomes hot, causing the blowing agent to decompose and form a gas. The gas formation destroys the integrity of the seal between the tray and the closure, permitting the seal to be opened easily after heating in a microwave oven.
