Quanzhou Harmony Bags Manufacturing Co., Ltd. shares the advantages and disadvantages of backpack zippers
1. Nylon zipper
Features: Nylon zipper is soft, with a smooth surface and bright and colorful colors. The most prominent features are lightweight, thin chain teeth, and flexibility. Among them, waterproof zippers are also a branch of nylon zippers, which have undergone certain special treatments: pasting PVC film, pasting TPU film, soaking in waterproof agent, coating waterproof zippers, and so on.
Disadvantages: Polyester monofilament is prone to aging and has a narrow range of applications for high and low temperatures.
2. Metal zipper
Features: Durable, soft, elegant and dignified.
Disadvantages: Chain teeth are more prone to detachment and displacement than other types of zippers, and due to the high cost of raw materials, they are more expensive than other types of zippers. Among them, aluminum zippers have slightly weaker strength performance compared to copper zippers of the same model. But after surface treatment, it has a decorative effect that imitates copper and has multiple colors, because its price is lower than copper, and its sales price has a certain competitive advantage.
The quality of the hiking backpack zipper is not only related to the quality of the backpack, but the appropriate combination of zipper and backpack style has a finishing touch effect. A small zipper has a great effect. Therefore, whether it's shopping or customizing a backpack, everyone should be careful not to overlook the zipper selection
