摘要:
The present invention teaches a film having a pealably sealable layer. When used in the vacuum packaging bag material context, the result is a vacuum packaging bag that a consumer can evacuate and hermetically seal. The consumer may later open the bag through a manual pealing action that does not require a tool and that does not result in wasting or destroying a portion of the vacuum packaging bag. The present invention also contemplates a variety of applications for the pealably sealable films, including preformed bags and bag rolls, as well as a variety of apparatus for manufacturing the films and appliances for utilizing the bags and bag rolls.

A vacuum bag comprises 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 a timer and/or sensor embedded or encapsulated by the inner layer. The timer and/or sensor can be used to monitor storage time, contents, and/or the condition of packaged products, or can be used to protect contents. 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.
摘要:
A bag for use in vacuum packaging comprises a first panel and a second panel overlapping each other. A valve structure is formed on the first panel for evacuating air and/or other gases from inside the bag when a suction source is placed over the valve, and for sealing the bag when the suction source is removed. The first panel and second panel can each include integrated features for forming a zipper or clasp for sealing the bag. 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.
摘要:
Resealable vacuum packaging bags and methods of manufacturing and using the bags are disclosed herein. In one embodiment, a bag includes a first panel and a second panel coupled to the first panel. The first and second panels each have a gas impermeable layer and a heat sealable layer. The bag further includes a first mating member projecting from the first panel and a second mating member projecting from the first or second panel. The second mating member is configured to selectively engage the first mating member to substantially seal the bag. In another embodiment, a method of using a resealable vacuum packaging bag includes opening a thermally sealed vacuum packaging bag and engaging a first complementary member on a first panel of the bag with a second complementary member on a second panel of the bag to substantially seal the vacuum packaging bag after opening the vacuum packaging bag.

A method for manufacturing a bag for use in vacuum packaging comprises forming a first panel having a receiving feature and a second panel having an insertion feature, such that the insertion feature can be removably connected with the receiving feature, thereby forming a zipper. Each panel comprises a gas-impermeable base layer and a heat-sealable inner layer molded from melt-extruded resin. The first panel is overlapped with the second panel, and three of four edges of the panels are heated such that the inner layers bond at the heated edges and the unbonded edge can be opened or closed via the zipper. Optionally, the bag can include a valve structure for evacuating the bag. 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.
