Waterproof and airproof zipper, simply called Airproof zipper, is a special zipper used in navigation and diving. Our products have the feature of airproof and waterproof performance with high safety. Our products are meshed by the teeth inside the adhesive tapes by a slider and then the flexible adhesive tapes join closely due to the compression from the outside teeth and at last achieve absolutely tightness. We can prevent the entrance of liquid, air, gas, water, smoke, dust and light. We have two types of products: open top and ends closed. Open top zippers suit open top soft container such as heat preservation life jackets and protective clothes (gas, oil and chemical protection). Ends closed zippers are used in diving suits, water walking balls, airproof luggage and altiplano first aid pressure bags.
