ABSTRACT:
A waterproof structure for zippers includes a waterproof layer formed on one side surface of two tapes of a half-finished zipper. The waterproof layer is formed by coating a layer of bonding glue on the one side surface of the two tapes and then the bonding glue has its upper layer stuck with an electroplating membrane. By so designing, external water can be prevented from seeping in the two tapes of the zipper, thus elevating waterproof effect of a zipper.
