Nylon zipper with coating film teeth refers to nylon zipper that has a layer of metal coating or other high-purity compound film applied to the surface of the teeth. Common colors of nylon coating film teeth include gold, silver, rose gold, etc. This type of zipper is decorative and suitable for lightweight fabrics.

It is important to note that the coating is only applied to the front surface of the zipper teeth. The back side, which is in contact with the fabric tape, and the sides are not coated. This type of zipper is suggested to be paired with spray-painted or electrophoretic pullers. Avoid pairing with electroplated pullers, as the inner cavity of electroplated pullers is typically rough and hard, which may damage the coating on the zipper teeth, causing it to peel off. In addition, please avoid ironing on the teeth, which may damage the metallic appearance. Long time washing may lead to color fading.
