ABSTRACT:
The present invention provides packaging capable of room-temperature storage of foods followed by simplified microwave heating. The package also permits heating in conventional ovens. The package includes a multi-ply container portion having a central recess surrounded by a sealing rim to which is heat sealed a lid which is flexible and non-extensible and has good barrier proporties. The inner surface of the container is amorphous polyethylene terephthalate to assure good heat sealing. The out ply of the container is crystallizable to provide sufficient dimensional stability during heating. The package can be retorted and vents itself when microwave heated, thus simplifying storage and preparation of foods.
