Abstract
An apparatus for surface heating of an object, such as a food object, in an oven by microwave energy which requires only a microwave interactive heater material and a support for it that is designed to obtain higher temperatures via a contact wall formed of stacked layers. In particular, in accordance with various embodiments, a primary panel defines a contact surface against which an object is disposed, and a secondary panel which is coextensive in area with at least an object heating portion of the primary panel is disposed adjacent to the primary panel at an opposite side thereof from the contact surface. Each of the primary panel and secondary panel is formed of a layer of microwave interactive heater material that is applied to a microwave transparent support material, such as paperboard. The layer of heater material applied to the primary panel covers at least the object heating portion thereof, and the layer of microwave interactive heater material applied to the secondary panel covers at least a part of a surface which faces toward the primary panel to an extent that is substantially coextensive with at least the object heating portion of the primary panel.
