发明名称 SYSTEM AND METHOD FOR FORMING AN INDICIA FOR USE IN VACUUM PACKAGING
摘要 A vacuum bag can comprise a first panel and a second panel, wherein each panel comprises a gas-impermeable base layer and a heat-sealable inner layer with at least one panel having indicia. The indicia can be informative, decorative, and/or functional, and optionally can be colored so that the indicia can be easily identified by a user. 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.
