Abstract:
1. A microwave energy interactive insulating structure comprising: a layer of microwave energy interactive material supported on a first polymer film layer; a moisture-containing layer joined to the layer of microwave energy interactive material; a second polymer film layer joined to the moisture-containing layer such that the moisture-containing layer is positioned between the microwave energy interactive material and the second polymer film layer, the second polymer film layer being joined to the moisture-containing layer in a predetermined pattern to define a plurality of first cells between the moisture-containing layer and the second polymer film layer, the plurality of first cells comprising a plurality of second cells being adapted to inflate in response to sufficient exposure to microwave energy, and the predetermined pattern comprising a plurality of lines of adhesion disposed between the moisture-containing layer and the second polymer film layer; and a plurality of physical apertures extending through each of the first polymer film layer, the moisture-containing layer, and the second polymer film layer, the physical apertures being arranged so that the plurality of first cells further comprises a plurality of third cells that are interspersed among the second cells, wherein for each third cell of the plurality of third cells, at least one physical aperture of the plurality of physical apertures extends at least partially through the third cell so that the at least one physical aperture inhibits any inflatability of the third cell, the plurality of third cells comprises a first one of the third cells and a second one of the third cells, the plurality of lines of adhesion comprises a first line of adhesion positioned between the first one of the third cells and the second one of the third cells, and a first physical aperture of the plurality of physical apertures is configured so that the first physical aperture extends at least partially through each of
