Abstract
A sealable and sterilizable package having a bottom of metal foil or light-gauge sheet with a thermoplastic lining and a lid of metal foil or light-gauge sheet with a thermoplastic lining sealingly adhered around its edge portion to the bottom lining to provide a fully sealed, sterilizable and shelf-stable container for food products or the like. The lid is manually peelable from the bottom, with defoliation of the lid lining along the locality of the seal, providing a neat and attractive appearance for the opened container. The lid lining is constituted of a material that effectively and reliably adheres to the metal surface of the lid at sterilization temperatures while forming with the bottom lining a complete but peelable seal.
