In daily use, the durability of a zipper impacts the lifespan of a product, especially for frequently used case and bag zippers. Normal zippers may experience the wear and aging of sewing lines over time, causing the zipper teeth to fall off. SBS AR zipper features a specially optimized structure that enhances durability.

First, utilizing high-strength sewing lines is a key factor. SBS utilizes high-strength sewing lines to prevent the teeth from falling out, reducing wear and aging during long-term use.

Second, the structure of the teeth and slider design requires optimization. The surface of the AR zipper teeth adopts a notchy design, locking the sewing line inside the notch. The inner cavity of the slider has been changed. Pulling and closing the board does not directly cause friction to the sewing lines, which helps reduce wear and tear.

In the resistance to reciprocation test, the average of SBS AR zippers’ pulling times reaches up to 10,000 times, far exceeding the industry standard of 600 times.

Designed specifically for cases and bags, the SBS AR zipper offers abrasion resistance. It also operates smoothly, even around corners. SBS AR zipper is extensively used by brands such as Decathlon, Delsey, Samsonite, Xiaomi, KALA. Y, etc.
