Abstract: An oven tray formed from a sheet of glass fiber or other non-metallic temperature resistant mesh generally having a horizontal warp and weft, coated with a fluoropolymer such as PolyfTetraFluoroEthyleneor, silicone compound, etc. that provides a low friction coefficient coupled with high temperature resistance and light weight. The mesh is sufficiently widely spaced so an air gap exists between strands of weft and warp to allow circulation of air. The oven tray improved the quality of cooked food items in a variety of high temperature environments by increasing the ventilation afforded to the food item. The oven tray is both lightweight and has low thermal conductivity. In order to improve the rigidity of the material, the individual strands of mesh are aligned with the main axes of the tray.

Abstract: Container for heating food in an electrical bread toaster or other radiant heating device comprises a closed or partially open pouch formed of flexible sheet material comprsing a woven fabric, such as glass or KEVLAR fibres, coated or impregnated with an electrically non-conductive heat resistant material, for example PTFE.

Abstract: Food heating method and apparatus using containing means, e.g., a pre-formed container 1, such as a relatively flat pouch or envelope comprising at least one panel made of flexible multilayer film with layers 3 and 5 of Perfluoralkoxy (PFA) and Fluorinated Ethylene Propylene (FEP), respectively, on a core layer 3 of Polytetrafluorethylene (PTFE). A sandwich or other foodstuff 23, baked beans or french fries, for example, “chips” or “frites”, can be heated by being inserted in the containing means which is then heated by a radiant heat applying device, such as an electric bread toaster. The containing means can be wholly of the multilayer film. The containing means can be in the form of an open bag, which is reusable, or it can be a closed bag sold with the food therein.
