Patent ID: 8604400

Claim:
A microwave heating construct, comprising: a first layer including a plurality of elongate microwave energy transparent areas and a plurality of elongate microwave energy interactive areas arranged in an alternating configuration; and a second layer including a microwave energy interactive area, the microwave energy interactive area of the second layer being superposed with the microwave energy transparent areas and the microwave energy interactive areas of the first layer, wherein the microwave energy interactive areas of the first layer and the second layer comprise a microwave energy interactive material operative for converting at least a portion of impinging microwave energy into thermal energy, the elongate microwave energy transparent areas of the first layer comprise the microwave energy interactive material in a deactivated condition, the microwave energy transparent areas of the first layer have a width of from about 0.10 to about 0.40 inches, and the microwave energy interactive areas of the first layer have a width of from about 0.25 to about 0.75 inches.
