1.Resin zipper

Features: Resin zipper is tough, abrasion-resistant, corrosion-resistant, colorful, and has a wide applicable temperature range. In addition, because the area of the upper and lower planes of the element is large, it is beneficial to inlay diamonds or gems on the plane, which makes the zipper more beautiful and luxurious, and the value is doubled, which becomes a practical craft decoration.

Disadvantages: Due to the large particle size and coarse feeling, the slippage is slightly worse (slightly inferior) than other types (nylon zipper, metal zipper) of the same type.

2.Nylon zipper

Features: Nylon zipper is soft, smooth surface, bright and colorful. The most prominent features are light weight, thin chain elements, and flexibility. Among them, the waterproof zipper is also a branch of the nylon zipper, which is a nylon zipper that has undergone some special treatments: PVC film, TPU film, waterproof agent soaking, coated waterproof zipper, and so on.

Disadvantages: Polyester monofilament is easy to age, and the applicable range for high and low temperature is narrow.

3.Metal zipper

Features: durable, soft, elegant and solemn.

Disadvantages: Chain elements are easier to fall off and shift than other types of zippers. Due to the high price of raw materials, they are more expensive than other types of zippers. Among them, compared with the same type of copper zipper, the aluminum zipper has a weaker performance. But after surface treatment, it has imitation copper and multi-color decoration. Because the price is lower than copper, its sales price has a certain competitive advantage.
