ABSTRACT OF THE DISCLOSURE A packaging material and a method of forming the packaging material into a flexible, disposable food container adapted to contain and maintain food in a fresh and sanitary condition, and to ship, display, heat and brown, and serve the food is disclosed. The method includes forming patches of microwave interactive material on a web of plastic and laminating the web of plastic to one side of a web of structural stock material to form a composite web; the microwave interactive material is sandwiched between the web of plastic and the web of structural stock material. Sealant is applied to portions of the plastic layer in registry with the patches of microwave interactive material to seal ends of the composite web. Printed graphics are applied to portions of the structural stock material layer in registry with the patches of microwave interactive material and the sealant. The formed container is sufficiently flexible to contain food having curved and irregular surfaces and to maximize contact of the food with the portion of the container housing the microwave interactive material. The container is sealed so that portions of the composite web extend as fins beyond the sealed ends of the food-containing portion of the container. The container also is capable of receiving food before the food is frozen to prevent portions or parts of the food from falling out of their proper place in the food packaging process.
