When the zipper teeth are closed, the peripheral TPU (thermoplastic polyurethane) of the zipper teeth is tightly combined together, the gap of the zipper can be well sealed with upper zipper teeth and lower zipper teeth, the thickness of the TPU layer of the zipper tooth is larger than that of the TPU layer of the zipper belt, and a convex edge is formed by adapting the TPU to coat and by the integral design. The utility model has the advantages of durability, low cost, water and air resistance, ultraviolet ray resistance, corrosion prevention, ageing and abrasion resistance, and the like.
Tightness
The DaSun Zipper will hold 200 mbar air pressure. The DaSun Zipper is less air-tight than the DaSun Zipper but is easier to open or close. Heavy bending may cause leakage. Please try to avoid!
