Abstract

A paperboard container for heating products placed therein by microwave energy having a first compartment substantially shielded from microwave energy and a second compartment permeable by microwave energy. The first and second compartments each include a top panel and a bottom surface, where a single bottom panel serves as the bottom surface for both of the first and second compartments. The container further includes a plurality of side panels extending upwardly from the bottom panel and a plurality of side panels extending downwardly from the top panels. Both of the first and second compartments are formed from a unitary, single sheet of microwave permeable paperboard material, wherein the first compartment includes a layer of microwave shielding material laminated to the portion of the sheet of microwave permeable paperboard material which forms a majority of the enclosing surfaces of the first microwave shielded compartment.
