Customer Problem / Requirements
Based on the customer’s application scenario and quality requirements, we recommended a No.7 Nylon TPU Waterproof Zipper with an auto-lock slider and customized puller.
This zipper type is especially suitable for outdoor apparel because the TPU-coated surface improves water resistance while maintaining a clean and modern appearance. Compared with ordinary nylon zippers, TPU waterproof zippers provide better protection against light rain, moisture, and outdoor environments. The No.7 size offers stronger durability than smaller zippers, making it ideal for jackets, coats, outdoor pockets, and high-frequency opening areas.
For the 16 cm closed-end zipper, we supplied customized colors including Black, White, Raw White, and Dark Blue. These were mainly used for pocket openings and smaller functional parts. For the 70 cm open-end zipper, we supplied Black, White, Raw White, Gray, Dark Blue, Greige, and Beige, suitable for front openings of jackets and coats.
To support smooth garment production, we arranged pre-production samples before mass production. The customer confirmed the zipper structure, color matching, slider style, and puller appearance before the bulk order started. During production, we controlled tape flatness, coating surface quality, zipper smoothness, slider locking function, and color accuracy. Each batch was inspected before packing to reduce production risk for the customer.
