About the application of watertight/airtight zipper

  • As the name of the "water/airtight " zipper indicates, the main feature of this zipper type is to prevent liquid and air leakage. You should notice the main difference compared to waterproof zippers, which can still leak air. To manufacture water/airtight zippers, the key technologies are air/watertight teeth/elements and seals. So we should also be careful when installing airtight/watertight zippers as you need to make sure the seal is installed properly to prevent leaks.

    Different techniques can be used to manufacture airtight/watertight elements and seals. Nickel silver, polyester and polyamide are just a few examples. Therefore, we can generally divide water/airtight zippers into two categories: plastic zippers or metal zippers. We are currently focusing on making more durable and affordable metal water/airtight zippers.

    From the main characteristics, we can guess that the main application of airtight/watertight zippers is heavy equipment that needs to be resistant to pressure and liquid. However, this is just one of many applications for this type of zipper.

    Below, we discuss several popular applications for airtight/watertight zippers. This guide will help you determine if an airtight/waterproof zipper is the right choice for your current needs.
