This is cheap, is thin layer plastic sheet before inflation, heaves after inflation and play shockproof effect, air anti-vibration was packed from 2000
Bag product is just studied and releases new departure, but basic principle, still using two layers of outer membrane as inflatable bag body, two layers of inner membrance constitute bag
Air valve film device on body, air valve film working principle are upon inflation, since external pressure is higher than air pressure in bag body, so two layers
Inner membrance meeting " being blown open ", allows gas can smoothly enter into bag body；After inflation, since air pressure is higher than external pressure in bag body,
And bag body can be expanded because of inflation, so that two layers of outer membrane near air inlet is no longer parallel, but be stretched around, therefore two layers
Inner membrance has pressed to bag body side by air pressure inside, is bent and fits together jointly with this layer of outer membrane, realizes that closing is located in two layers
Air inlet between film achievees the effect that air non-return.
In order to preferably " blow " two layers of air valve film open, application number 200610067311.5 " there is seal to hold one's breath automatically

Section " form, production technology simplify, without to mark step；And by the inflatable area of the left and right settings in perpendicular hot-sealing line,
After inflation alternative original " heat seal point (2c) ", and the bottleneck shape of outer contour energy self-assembling formation air inlet, not only make to inflate
Smooth convenience, and this structure is due to the presence without " resistance to thermal center " height allows inner membrance height from original 70mm
It is shortened above to 50mm hereinafter, save the cost can not be estimated.
But after actually using a period of time, inventor has found that above scheme also has place to be modified, such as due to heat resistant oils
Ink-stick between the entire bag body of lateral direction penetrating, therefore inflate before, it is necessary to preset and pass through the closed of the heat resistant oils ink-stick
Hot-sealing line, to prevent gas from leaking out from perforation place of heat resistant oils ink-stick；Secondly, between each inflatable area due to
