A metal tray has its inner and outer surfaces coated with a plastic material. Within the tray is a first susceptor unit which includes a layer of corrugated paperboard composed of A-flutes secured to the underside of a substrate having a metallized foil secured to its upper side. A food item to be heated is supported on the first susceptor unit. A second susceptor unit overlies the food item, the second susceptor unit having a downturned flange inserted between one side of the tray and one side of the food item.

A package combination for use in a microwave oven comprising a metal tray including a bottom wall and a continuous side wall extending upwardly from said bottom wall and forming an open top, the inner and outer surfaces of said walls having a plastic coating thereon, a first susceptor unit including a metallized film, a dielectric substrate integral with said film and a layer of corrugated dielectric material secured to the underside of said substrate, said first susceptor unit being loosely received in said tray with said corrugated layer engaging said bottom wall so as to locate said metallized film in a raised or spaced relation with respect to said bottom wall, a foot item on said first susceptor unit, and a second susceptor unit generally closing said open top and loosely overlying a substantial portion of the food item including a metallized film and a layer of dielectric material thereabove, said second susceptor unit constituting the sole means overlying said food item so that microwave energy is permitted to enter said metal tray only through its said open top and said second susceptor unit.
