The zipper is one of the very important accessories of the backpack
, and it is directly related to the service life of the backpack. Backpack zippers are divided into different hair types according to different properties. According to the material classification, they can be divided into three types: resin zippers, nylon zippers, and metal zippers. Next, the manufacturer will tell you what are the characteristics of backpack zippers of different materials, let's learn about it together. 1. Resin zipper Features: The resin zipper has tough texture, wear resistance, corrosion resistance, colorful colors, and a wide temperature range. In addition, because the upper and lower planes of the chain teeth have a larger area, it is beneficial to inlay diamonds or gems on the plane, which makes the zipper more beautiful and luxurious, doubles its value, and becomes a practical craft ornament. Disadvantages: Due to the large particles of the chain teeth, it has a rough feeling, and the lightness of the pull is slightly worse (slightly inferior) than other types of zippers of the same type (nylon zippers, metal zippers). 2, nylon zipper Features: nylon zipper is soft, smooth surface, bright and colorful. The most prominent features are light weight, thin chain teeth, 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 application range for high and low temperature is narrow. 3, metal zipper Features: durable, soft, elegant and solemn. Disadvantages: The chain teeth 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, aluminum zippers are a bit weaker than copper zippers of the same model. However, after surface treatment, it has the decorative properties of imitating copper and multi-color. Because the price is lower than that of copper, its sales price has a certain competitive advantage. The quality of the backpack zipper is not only related to the quality of the backpack, but the proper zipper and backpack style have a finishing touch. The small zipper has a great effect. Therefore, whether it is buying or customizing a backpack, everyone must be careful not to ignore the zipper selection.
