Abstract: Liners for cooking vessels, cooking systems, and methods of making liners for cooking vessels are disclosed. The liner can be a multi-layer liner having a bag-like structure with a closed bottom having a bottom edge, a top opening having first and second top edges, and two sealed sides. The liner can have a first side seal extending along a first end from the top opening toward the bottom edge and a second side seal extending along a second end from the top opening toward the bottom edge. The liner material can include an aluminum foil sheet thermally laminated to a polymer film. The polymer film can include a biaxially-oriented polyethylene terephthalate layer coextruded with an amorphous polyethylene terephthalate sealant layer.

Abstract: A heat-shrinkable polymeric cover provides a safe, low cost way to cover a food service pan during food preparation, storage, cooking, transport and reheating. The food pan cover can have a closed top end having a first top edge and a second top edge and an open bottom end having a first bottom edge and a second bottom edge. A first side seal extends from the top end to the bottom end, and a second side seal extends from the top end to the bottom end. A gusset can be formed between the first top edge and the second top edge. The food pan cover can be formed from a single layer of heat-shrinkable polymeric material capable of withstanding a temperature of at least about 400 degrees Fahrenheit.

Abstract: An apparatus, system, and method for forming an improved barrier between a pan, such as a food service pan, and a substance, such as food, contained therein using a contour fit pan liner are provided. The apparatus includes a pan liner having a contoured bottom edge that is custom fit within a food service pan to cover an interior surface of the pan. The contoured edge of the pan liner conforms to the shape and size of the food service pan and does not have any dog ears, ears, or tails that are typical of conventional pan liner. The contour fit pan liner system includes a pan and a contoured or shaped liner for forming an improved barrier between an interior surface of the pan and food that can be disposed therein using a pan liner having a contoured bottom edge that is custom fit to the shape and size of the pan.
