Abstract
A microwave energy interactive insulating material is provided. The material may include a susceptor film comprising a microwave energy interactive material supported on a first polymeric film layer, a moisture-containing layer superposed with the microwave energy interactive material, and a second polymeric film layer joined to the moisture-containing layer in a predetermined pattern, thereby forming at least one closed cell between the moisture-containing layer and the second polymeric film layer. The closed cell is capable of inflating upon exposure to microwave energy.
Claims19
A microwave packaging material comprising:
- (a) a susceptor film comprising a microwave energy interactive material supported on a first polymeric film layer;
- (b) a moisture-containing layer superposed with the microwave energy interactive material;
- and
- (c) a second polymeric film layer joined to the moisture-containing layer in a predetermined pattern, thereby forming at least one closed cell between the moisture-containing layer and the second polymeric film layer,
- wherein the moisture-containing layer is positioned between the microwave energy interactive material and the second polymeric film layer.
