Abstract
A microwave energy interactive heating sheet includes at least two layers of microwave energy interactive insulating material joined to one another, where each layer includes microwave energy interactive material supported on a first polymer film layer, a support layer joined to the microwave energy interactive material, and a second polymer film layer joined to the support layer in a predetermined pattern, so that a plurality of expandable cells are defined between the support layer and the second polymer film layer. The expandable cells are operative for inflating upon sufficient exposure to microwave energy.
