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.
