Abstract
The invention discloses a gas packing body with a dual protection function. The gas packing body comprises two layers of gas packing body outer films and check gas valves arranged between the two layers of the gas packing body outer films. The peripheries of the two layers of the gas packing body outer films are connected with each other to form a packing bag body. A seal cavity is arranged in the packing bag body. The seal cavity is divided into a plurality of gas storage chambers by a plurality of heat-seal lines applied to the packing bag body. The check gas valves serve as gas inlet valves of the gas storage chambers. The gas packing body is characterized in that the two ends of the packing bag body are provided with folded parts folded oppositely; the two side edges of the folded parts at the two ends are connected with the heat-seal lines or heat-seal points to be fixedly connected with the packing bag body, and two containing cavities which are matched with each other oppositely are formed. According to the gas packing body, the safety of packed products is increased by a large margin; the gas packing body is simple in structure and convenient to produce and machine.
Description
Technical field
The present invention relates to gas flush packaging body technique field, relate to a kind of gas flush packaging body with double protection functions more specifically.
Background technology
Traditional packing, as protected beautiful jade for asking rain, EPE, paper etc. as padded coaming, are difficult to the demand adapting to Developing in the megatrend of environmental protection instantly.In recent years, the existing use using air as package media padded coaming.
The structure of gas flushing pouch common at present uses all existing defects; If China Patent Publication No. is 103241456A, disclose a kind of double buffering gas flushing pouch and manufacture method thereof, comprise by inflatable plastic press from both sides that film formed be provided with article container chamber and one end is article puts into the outer sack of mouth, inflatable plastic folder film has multiple bar shaped plenum chamber structure, and each bar shaped plenum chamber is communicated with inflation overall channel by inlet non return check valve; Pocket structure in a supporting film formation is lined with in inside, the article container chamber of outer sack is gone back, supporting film edge and the article of described outer sack are put into together with mouthful edge conjunction, and have certain distance bottom the outer sack of supporting film distance from bottom, do not contact with bottom supporting film bottom it after inflation to make outer sack.This air bag is that do not inflate and can fold arbitrarily when production and accumulating, taking up room little reusable again, local can form multi-buffer effect by five layers of plastic sheeting through heat seal and folding manufacture, to meet the commodity stronger shockproof requirement in local.But, because article put into air bag from top to bottom, and by air bag to bottom it and sidepiece carry out parcel protect; although simple to operation, air bag is once leak gas; the article put into inside sack can be caused to lose protection, its safety performance still needs to improve at once.And for example Chinese patent notification number is 203682178U, denomination of invention is a kind of self-closing type air inflation packaging bag with inner lining film, include two panels adventitia and two panels inner membrance, two panels adventitia periphery is interconnected to form packaging bag body, annular seal space is provided with in body, some hot-sealing lines are applied with in described annular seal space, annular seal space is divided into multiple sealing column chamber, described inner membrance coordinates with adventitia and forms filling channel, described filling channel is divided into main gas charge passage and point filling channel, in described each sealing column chamber, correspondence is provided with a point filling channel, described main gas charge passage and each point of through setting of filling channel, described point of filling channel and the through setting in sealing column chamber corresponding with it, it is characterized in that: described packaging bag body is folded with formation two fold planes and a folded edge, the side of folded edge make two fold planes of this folded body of packaging bag be connected to one by arranging to connect hot-sealing line or connect heat seal point, described packaging bag body forms a containing cavity by folded edge with being connected hot-sealing line or connecting heat seal point, inner lining film is provided with in described containing cavity, inner lining film is also folded with, the side of inner lining film is fixedly connected with packaging bag body by connecting hot-sealing line or connecting heat seal point, the folded edge of inner lining film and the folded edge interval of packaging bag body are arranged.This patent structure mainly prevents packaging bag from being poked by the article corner of its inside; improve its safety guard-safeguard performance to a certain extent; but; packaging bag is still likely punctured from outside; leak gas; in this case, article still can be made unavoidably to lose protection, be difficult to meet the demand used.
