Coil zipper also known as nylon coil zipper is a type of zipper whose teeth/elements are made from coiled monofilament that is traditionally nylon. Finally the product is completed when the nylon coiled teeth are sewn into the zipper tape.
- Metal zipper consists of teeth made of metal, they can also be made from brass, aluminium or nickel and they are designed to interlock like clasped hands, linking the row thus creating a “continuous clothing closure”.
These are identical to metallic zippers, except that the teeth are plastic instead of metal. Metal zippers can be painted to match the surrounding fabric; plastic zippers can be made in any color of plastic. Plastic zippers mostly use polyacetal resin, though other thermoplastic polymers are used as well, such as polyethylene.
