The zipper tape features a strong adhesive backing that withstands high traffic and provides reliable performance. The high-quality Oxford canvas fabric surrounding the zipper enhances durability, making it suitable for various applications.

This self-adhesive zipper is versatile and can be used in both indoor and outdoor settings. It is ideal for greenhouses, grow tents, plastic films, and dust barriers.
