SUBSTANCE: pressure-tight zipper comprises two belts made of a flexible material whose facing each other edges are pressed one to another by means of connecting two groups of leveled teeth when lock passes along the zipper. At least outer layers of two belts and teeth are made of materials which are chemically welded to each other. The teeth are chemically welded to the belts at the moment of injecting molding of the teeth. Each of the teeth is made by means of injecting molding from two halves arranged from the opposite sides of the edges of the belts so that they are secured to the belts by means of welding.
