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.

Abstract: A package made of metal foil or light-gauge sheet, having a bottom and lid each lined internally with a lacquer and heat-sealed together by means of the lacquer to provide a sealed, sterilizable, shelf-stable container for food or the like, which does not require refrigeration for storage. 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. Specifically different vinyl resin based lacquer systems may be employed for the bottom and lid linings.
