YKK zipper metal single opening garment zipper

There are basically three kinds of metal zippers: metal, nylon and plastic metal zippers. For aluminum alloy or copper metal zippers, pay attention not to be affected by moisture, alkaline and acidic substances during use and storage, so as to prevent metal teeth from being affected by moisture, oxidation and corrosion. For nylon and injection molded metal zippers, pay attention to high temperature to avoid deformation. Because its wear resistance, hardness and strength are not as good as metal zippers, it should be more careful than metal zippers, and the teeth must be pulled gently.
