Definition: Airtight zipper is a zipper that cannot be penetrated by gas.
Of course, there are various airtight zipper grades. The so-called airtight zipper is generally defined as ipx8 grade waterproof zipper.
Airtight zipper doesn’t mean fully airtight in all environments but it depends on the pressure received. If it is between one atmosphere and two atmospheres, it is not leaking, which is considered as a qualified airtight zipper. If the pressure exceeds 2 atmospheres, it will leak.
Working principle: So, here comes the question, what is the working principle of the airtight zipper? How is waterproof achieved?
In fact, the airtight zipper is evolved from the ordinary zipper. It consists of three parts: joint pull teeth and textile fabric. On the basis of this, the airtight zipper side adds a layer of waterproof material-tpu film, which is poured through continuous high temperature. When the membrane tpu is applied to the textile fabric, it is integrated with the fabric and combined with the precision of the pull teeth to be tightly sealed, and the zipper can be sealed to achieve airtight and waterproof zipper.
Application areas:
Airtight zippers are widely used, and when they are put on the market, they will surely cause a waterproof revolution in outdoor equipment.
In outdoor wading activities, snorkeling, swimming, river tracing, surfing, boating, and rafting can all be excellent equipment.
Now the main products are: diving pockets, tracing bags, bicycle bags, swimming bags, diving equipment bags, etc.
How to maintain the airtight zipper? The airtight zipper is the same as normal zipper that you don’t need to maintain it especially. Just clean it by water. But there is some difference from the normal zipper. It is very hard to seal the airtight zipper especially the first time to pull it. So you will need to lubricate frequently.
