When it comes to air column bags, most people don't know what it is, but people who often buy fragile products are no strangers to them. It is the development of foam cushioning. The topic of environmental protection in the current era is indispensable. The original cushioning material such as foam is very harmful to the environment, and the air column bag has become a new cushioning product because it has no impact on the environment. Also, what are the advantages of using air column bags? Let's take a look.

Compared with foam, on the one hand, because the color of the air column bag is transparent, it can give people an intuitive feeling about the product. It will give customers a sense of security. On the other hand, if the air column bag is used for the packaging, the product will increase the overall feeling, because the visual error may be caused by the mirror principle.
Compared to traditional manual packaging such as wrapping paper, using an air column bag simply places the product in the bag and inflates it using an inflatable device. Maybe you think there is no difference between one-piece or two pieces, but just like removable printing and engraving printing, when the quantities are large, using an air column bag will save labor, effort, and time.
Compared with traditional packaging materials, the cushioning of the air column bag uses air, not the impact resistance of the packaging bag itself. In reality, it's just a thin two-layer plastic and takes up relatively little space when not inflated, which invisibly reduces inventory costs.
The advantages of this feature essentially stem from the viscoelastic properties of the air column bag itself. This feature ensures that the air column bag can support up to 200kg without being squeezed when fully inflated. Is the compression resistance good compared to traditional cushioning materials?
This is mainly due to the design structure of the air column bags independent of each air column. When multiple air chambers are damaged due to external factors, the cushioning of the product will not be greatly affected, and the safety performance is trustworthy.

The air column bag is a kind of "magic" packaging: when the gas is filled into the bag, it can be sealed only when the gas enters, but it cannot be sealed without the gas entering. It's amazing that a person stands on the air column bag which will not explode. Why does the air column bag have these excellent properties? Here is a detailed explanation of the technical principles behind the "magic" of the air column bag.
This starts with the reverse air shut-off valve membrane of the air column bag. When manufacturing the air column bag, it will laminate two layers of reverse air valve membrane as the inner membrane. The function of the two-layer air valve membrane is to provide an air inlet channel for each air column during the inflation process. At the same time, after the air pressure is over, the reverse air shut-off valve membrane will be tightly attached to one side of the air column bag on the outer membrane. Using the bonding function provided by the previously prefabricated heat sealing points, the gas circuit is tightly closed by the air pressure.
In fact, there are many similar principles in life, such as football, basketball and swimming ring, which relies on the air pressure generated by the incoming gas to close the intake circuit.
This is due to the material of the air column bag. The raw material of the air column bag is nylon co-extruded film, which is a new material technology.
Through multi-die co-extrusion technology, different materials can be co-extruded into the same film. Nylon (PA) is located on the inner layer to provide superior toughness and resistance. Polyethylene (PE) is compressible and can provide heat sealing properties. Generally, the structure of the seven-layer nylon co-extruded film used for air column bags is PE-PE-TIE-PA-TIE-PE-PE. Different film layers provide different functions, and different film layers converge into the same film.
Why can the air column bag hold gas for such a long time? There is still enough gas in the bag to protect the product from damage after half a year. This is also provided by the nylon co-extruded film of the air column bag. Nylon is a barrier material with strong gas retention. Therefore, the gas column bag can hold up to six months of gas.
As a consumer, after learning the basic technology of the air column bag, you will understand why the air column bag is so "magical".
