Definition: airtight zipper, as the name suggests, is a zipper that cannot be penetrated by gas.

Of course, there are all kinds of airtight zippers, generally defined as ipx8 waterproof zippers, which are called airtight zippers.

Airtight zipper does not mean no air leakage. It depends on the air pressure. If there is no air leakage between one atmospheric pressure and two atmospheric pressures, it is a qualified airtight zipper. If the pressure exceeds 2 atmospheres, there will be air leakage.

Working principle: so, the question is, what is the working principle of air tight zipper? How is waterproof achieved?

In fact, the airtight zipper is evolved from the ordinary zipper, which is composed of three parts: Joint pull teeth and textile fabric. On this basis, the airtight zipper side adds a layer of waterproof material TPU film. Through continuous high-temperature pouring of the compound film TPU onto the textile fabric, it is integrated with the fabric and tightened in combination with the precision of the pull teeth, so that the zipper can be sealed without air leakage and waterproof.
