A microwave susceptible insulated packaging material includes a thermal insulating layer, which may be a fiberfill batt. The insulating layer is laminated to at least one layer of a co-extruded film which has been coated on one surface with a microwave susceptible material, such as aluminum or aluminum coated with a food-safe contacting polymer sealant. The packaging material can be used to form a container, such as a pouch, or as a label or as a lining for a container. The packaging material may be coated also with a printable coating material.

What is claimed is: 1. A microwave susceptible insulating label stock, comprising: a sheet of face material formed as a bi-layer film having a first layer and a second layer, wherein said second layer has a lower melting temperature than said first layer; a microwave susceptible coating applied to a surface of the second layer, said coating having a thickness between 20 and 100 Angstroms; and a thermal insulating layer having a thermal resistance in the range of 0.05 to 0.5 CLO (0.0077 to 0.077 m2*K/W) laminated to the sheet to form the insulating label stock having a thickness of at least 0.0075 inch (0.0190 cm). 2. The insulating label stock of claim 1, wherein the thermal insulating layer comprises a fiberfill batt. 3. The insulating label stock of claim 1, further comprising a printable coating applied to a surface of the face material. 4. The insulating label stock of claim 1, wherein the first and second layers of the face material are formed from a thermoplastic material selected from the group consisting of: polyester, polyethylene and polypropylene. 5. The insulating label stock of claim 1, wherein the microwave susceptible coating is a coating material selected from the group consisting of: aluminum, stainless steel, nickel/iron/molybdenum alloys and nickel/iron/copper alloys. 6. The insulating label stock of claim 1, further comprising a polymer sealant layer applied over the microwave susceptible coating. 7. The insulating label stock of claim 6, wherein the polymer sealant layer is formed from a material selected from the group consisting of: polyethylene, polyester and copolymers and mixtures of such polymers. 8. The insulating label stock of claim 1, wherein the label stock has outer edges and wherein said edges are sealed. 9. The insulating label stock of claim 8, wherein said edges are sealed with a sealant formed from a material selected from the group consisting of: polyethylene, polyester and copolymers and mixtures of such polymers. 10. The insulating label stock of claim 3, wherein the printable material has been printed. 11. An insulated container for holding foodstuff, comprising the insulating label stock of claim 1 applied to a surface of the container for holding foodstuff. 12. The insulated container of claim 11, wherein the container defines an internal volume and the insulated label stock is applied to the container to surround the internal volume.
