With practical buffering effect, light inexpensive, and the features such as simply use mode of operation.The most common inflation padded coaming
For the gas chamber material for being prefabricated into bag, it is chiefly used in the packet of electronic product packaging, Wines packing, milk powder packaging and other fragile articles
Dress.
When in use, compressed gas flows into gas chamber via inflation air flue 13 from two layers of air valve film 14, until in gas chamber
When air pressure is identical as compressed gas air pressure, the gas inside and outside gas chamber forms dynamic equilibrium, and air valve film is by plenum interior gas at this time
It is depressed into the side of gas storehouse body membrane, gas passage is closed, and has achieved the purpose that air valve closed gas after inflation, traditional gas
The non-return valve check principle of room material is as shown in Figure 2.
In traditional gas chamber material gas replenishment process, compressed gas needs to branch in each air column by inflating air flue.
1) this kind of airing form needs the inflation air flue for connecting each gas chamber unit, and the compressed gas being charged inflates air flue by this
It separately flows into each gas chamber unit, and the inflow of gas can only be from valve port while in one-way flow air inlet chamber, for gas chamber
The aerated materials volumetric efficiency of longer dimension is low；2) inflation air flue loses function after the completion of inflation, forms extra part simultaneously
Influence aesthetics；3) each gas chamber unit has an independent non-return valve, when single gas chamber breakage will affect entire inflation
The function of material equally destroys firm and buffer level of the product in gas chamber material；4) traditional air valve film and parallel air column
Structure limit the structure changes of aerated materials and make it can only be with the basic unit variation of the width of air column, it is difficult to it is not right to realize
The structure application of the irregular shapes such as title, radiation shapes.

The storage duration of coffee bean is grown.Most commonly seen valve body is two kinds: rigid plastics valve and PVC valve.As shown in figure 3, hard is moulded
Material valve be by the way that silica gel thin slice is fixed in PE shell, cannot be prefabricated in bag making process, can only the reheating sealing after bag making
Fixed, gas discharging is convenient, can extrude gas in bag with hand, will not obstructing airway, but obturation effect is limited, is applicable to anti-
Strike-on is opened, product of the short term stored in vacuum bag.As shown in figure 4, PVC valve is not required to seal, it is attached to outside bag body after bag making
Side, the check that PVC pastes valve is realized by the glue-line of modest viscosity, and gas is extracted outside bag body by glue-line, is taken out
Gas low efficiency, gas in bag could be discharged by needing to be equipped with specific aspiration pump, and obturation effect is good, suitable for being long-term stored at vacuum
Product in bag.
The development of electric business promotes the package design to flexible and changeable product mix, customization, automation and high efficiency
Operation becomes the new demand of nowadays electric business packaging.Traditional charge valve can satisfy automated production, but the structure of its air valve,
Size and position limit the variation of inflation product structure, limit inflation the degree of automation and big specification of aerated product
