The present invention relates to a container for the microwave heating of a food product in which a sheet of barrier material is sealed around a food product to a blank having one or more panels which can be folded to assemble a container. The sheet of barrier material forms a pocket inside which a food product may be disposed. The sheet of barrier material is sealed to one of the panels, so that a peripheral outer portion is formed to separate the food product from the remaining panel or panels. The barrier material may be moisture impervious, and may be sealed to the blank using a vacuum platen or heat-sealing methods. A microwave susceptor can be disposed on the blank, which is made from a material suitable for microwave heating such as a polymer and paperboard laminate.
