A coating coil zipper is a type of zipper that has a thin coil of nylon or polyester tape sewn onto each side of the zipper teeth, and a coating applied over the coil and teeth. The coating can be made from materials such as polyurethane, PVC, or TPU (thermoplastic polyurethane). The purpose of the coating is to make the zipper more durable, water-resistant, and smoother to operate.

Coating coil zippers are commonly used in outdoor apparel, luggage, and bags, as they provide better protection against the elements than regular zippers. They are also often used in high-performance sportswear because they are lightweight and flexible, allowing for greater freedom of movement.

The advantages of coating coil zippers include:

1. Durability: The coating provides extra protection to the zipper teeth and tape, making it less likely to break or snag.
2. Water resistance: The coating makes the zipper water-resistant, preventing water from entering through the gaps between the teeth.
3. Smooth operation: The coating helps to reduce friction between the teeth and tape, making it easier to zip and unzip.
4. Lightweight and flexible: The thin tape and coating make the zipper lightweight and flexible, making it ideal for use in sports and outdoor apparel.
5. Versatility: Coating coil zippers are available in various colors, sizes, and lengths, making them suitable for different types of garments and accessories.
