SYSTEM AND METHOD FOR FORMING AN INTEGRATED TRAY FOR USE IN VACUUM PACKAGING |
摘要 |
A bag for use in vacuum packaging can comprise a first panel and a second panel overlapping each other. One or more trays for retaining a perishable or other product is formed on one or more of the panels. Each tray can optionally have ridges for suspending a product above the tray so that liquid can collect in the tray. In one embodiment, a method for forming such a bag between a cooling roll and laminating roll includes feeding a gas-impermeable material to a nip formed between the rolls. Resin is extruded to the nip such that the resin fills a plurality of cavities of the cooling roll, forming an inner layer that adheres to the gas-impermeable material. A resultant sheet is then folded to form the first and second panel and sealed such that an envelope is formed. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims. |
