Abstract
The utility model relates to the field of protection apparatuses of material transportation, and in particular relates to a unidirectional double-face valve type inflatable packaging bag. The unidirectional double-face valve type inflatable packaging bag comprises a packaging bag body and an air valve, wherein the air valve comprise an upper membrane, a lower membrane and an air valve membrane, the upper membrane and the lower membrane are respectively connected with the air valve membrane in a hot melting manner provided with an air flow passage, and the upper membrane and the lower membrane are respectively in sealed connection with the opening of the package bag body. Furthermore, high-temperature-resisted anti-fusion-welding coatings are respectively printed on the upper membrane, the lower membrane and the air valve membrane. The unidirectional double-face valve type inflatable packaging bag has the following beneficial effects that a double-face inflatable valve is adopted, so that the inflating speed of the packaging bag is faster, and the packaging efficiency of the material is improved.
Description
Technical field
The utility model relates to the fender guard field of article transportation, refers in particular to a kind of unidirectional double-face valve formula gas flushing pouch.
Background technology
The development of logistics at present rapidly, and is strict more to the packing requirements of article, can not satisfy the demands through using measure protection article such as newspaper, cloth waste, and make article impaired easily.In the market more use have minute bubble plastic device be used for protecting article, but these had air the bubble membrane volume big, it is inconvenient to store transportation.Gas filed again packaging bag in the time of can using is also arranged, but owing to be existing inflation, the air valve of the single face air inlet of using at present, intake velocity is slow, influences packaging efficiency.
Summary of the invention
For overcoming the above problems, the utility model provide a kind of can two-sided air inlet, the unidirectional faster double-face valve formula of aeration speed gas flushing pouch.
A kind of unidirectional double-face valve formula gas flushing pouch; Comprise packaging bag body and air valve; Said air valve comprises film, following film and air valve film, and said upward film is connected with air valve film hot melt respectively with following film and is provided with gas flow, and the said film of going up is tightly connected with packaging bag body openings place respectively with following film.
Further, said going up on film, following film and the air valve film is printed with high temperature resistant anti-melting welding coating respectively, and the said film of going up is connected with air valve film hot melt on printed coating respectively with following film.
The beneficial effect of the utility model is: the utility model adopts two-sided charge valve, makes the aeration speed of gas flushing pouch faster, improves article packing efficient.

The specific embodiment
In conjunction with accompanying drawing 1-6; A kind of unidirectional double-face valve formula gas flushing pouch; Comprise packaging bag body 1 and air valve 2; It is characterized in that: said air valve 2 comprises film 3, following film 4 and air valve film 5, and said upward film 3 is connected with air valve film 5 hot melts respectively with following film 4 and is provided with gas flow 7, and the said film 3 of going up is tightly connected with packaging bag body 1 opening part respectively with following film 4.Said going up on film, following film and the air valve film is printed with high temperature resistant anti-melting welding coating 6 respectively, and the said film 3 of going up is connected with air valve film 5 hot melt on printed coating 6 respectively with following film 4.
When inflation, air gets in the packaging bag body 1 through air valve 2.After inflated, because the air pressure in the packaging bag body 1 is higher than external pressure, at this moment, the air in the packaging bag body 1 is closed air valve 2, so just can realize sealing and need not to weld, and prevents escape of gas.
Claims (2)
1. unidirectional double-face valve formula gas flushing pouch; Comprise packaging bag body and air valve; It is characterized in that: said air valve comprises film, following film and air valve film; Said upward film is connected with air valve film hot melt respectively with following film and is provided with gas flow, and the said film of going up is tightly connected with packaging bag body openings place respectively with following film.
2. unidirectional double-face valve formula gas flushing pouch according to claim 1 is characterized in that: said going up on film, following film and the air valve film is printed with high temperature resistant anti-melting welding coating respectively, and the said film of going up is connected with air valve film hot melt on printed coating respectively with following film.
