Abstract
A microwave energy interactive structure for heating, browning, and/or crisping a food item in a microwave oven includes a plurality of layers including a layer of microwave energy interactive material and a substantially continuous tie layer. The tie layer includes a thermoplastic material. Upon sufficient exposure to microwave energy, the tie layer softens and allows the adjacent layers to separate from one another to define a void between the respective layers.
