Abstract:
1. A microwave energy interactive structure comprising: at least one peripheral edge; a first susceptor film comprising a first layer of microwave energy interactive material supported on a first polymer film; a moisture-containing layer joined to the first layer of microwave energy interactive material; an adjoining layer joined to the moisture-containing layer such that the moisture-containing layer is disposed between the susceptor film and the adjoining layer, the adjoining layer being joined to the moisture-containing layer by a discontinuous adhesive layer, wherein the discontinuous adhesive layer comprises a plurality of joined areas spaced apart from one another by unjoined areas, the unjoined areas being at least partially interconnected to define at least one passageway that is in open communication with the at least one peripheral edge for allowing water vapor to be transported through the at least one passageway and to be released at the at least one peripheral edge, the at least one passageway being generally parallel to the moisture-containing layer; and a second layer of microwave energy interactive material on a side of the adjoining layer opposite the moisture-containing layer.
