Abstract

A water-resistant zipper comprises two zipper tapes and two groups of zipper teeth respectively disposed on the two zipper tapes. Each of the zipper tapes comprises a base tape and a water-resistant layer covering the base tape. The zipper teeth are disposed on the water-resistant layer. That is, the water-resistant layer is first disposed on the base tape, and then the zipper teeth are disposed on the water-resistant layer. The water-resistant zipper using the structure is simple to process and good in water-resistance effect.
