Adhesive band together.
Its principle is as follows：Article is internal from opening loading bag, is then sealed opening using the concave convex button one at flange,
Then two flange are bonded together again, are vacuumized in most back pkt. body.After vacuumizing, since the pressure of external atmosphere pressure causes
Fitting is drawn close in bag body both sides in opposite directions, and there is one flange of concave convex button to be located at bag is internal, bag body both sides tightly push down concave convex button one,
It can either prevent concave convex button one from disengaging, can also improve the leakproofness of one snapping of concave convex button, pass through be bonded together flange
Adhesive band can be further ensured that the reliable and stable and sealing performance that concave convex button one connects, and be operated during the sealing of this compressed bag
It is convenient.
In above-mentioned vacuum compression bag, concave convex button two is additionally provided on the side of the flange, the concave convex button two is close
The another side edge of the flange, the adhesive band is between the concave convex button one and concave convex button two.Pass through three seals and company
It connects, further lift-off seal.
In above-mentioned vacuum compression bag, the internal portion of bag that the concave convex button one is closed forms the first space, the bumps
Flange between button one and concave convex button two forms second space, and the bag body, which is equipped with, can make in the first space outside gas flow
The first unidirectional extraction valve on boundary；The the second unidirectional pumping that can make that gas flow is extraneous in second space is additionally provided on the bag body
Valve.After the first space and second space are vacuumized by the first unidirectional extraction valve and the second unidirectional extraction valve, bag body both sides
It squeezes flange and draws close fitting, while the negative pressure of second space also promotes flange to draw close fitting, double action ensures bag body opening
Sealed reliable.
In above-mentioned vacuum compression bag, the adhesive band is resin pressure sensitive adhesive band.When initial, adhesive band one side is pasted
Wherein on the flange of one side, there is barrier paper on opposite side, when use removes barrier paper, is bonded with the flange of both sides.
Its thickness is small, and adhesive effect is good.
In above-mentioned vacuum compression bag, the bag body is made of PET, and the medial surface of the bag body is coated with aluminium foil
Layer, the lateral surface of the bag body are pasted with layers of kraft paper.So can it is moisture-proof, be protected from light, there is good water proof, oxygen barrier,
And it is wear-resisting, service life is long, can measure body it is customized for different size, the compressed bag of pattern, such as can be made into flat mouth bag, stereoscopic bag,
A variety of patterns such as bellows pocket.Product need to be detected through GB and ASTM standard, and product meets the requirement in terms of environmental protection.
Compared with prior art, the flange with concave convex button one stretches into the internal portion of bag in the utility model, after vacuumizing,
The pressure effect of external atmosphere pressure is lower so that fitting is drawn close in bag body both sides in opposite directions, bag body both sides tightly push down concave convex button one, have
Effect prevents concave convex button one from disengaging, and substantially increases the sealing performance of one snapping of concave convex button, and is grasped during the sealing of this compressed bag
Facilitate.
