Abstract
New composite materials useful for wrapping food items to be cooked by microwave energy comprise a dielectric substrate substantially transparent to microwave energy which substrate is coated and/or imbibed with one or more microwave susceptor materials, the type and amount of said susceptor material or materials being adequate to allow said materials to absorb a portion of both the electric and the magnetic field components of said microwave energy and convert said energy to heat to rapidly brown or crispen the surface of the food item adjacent thereto without substantially impeding the ability of the microwave energy to penetrate the susceptor material and cook the food item.
