This SBS ultraviolet light variable zipper features a waterproof film on the surface of the tape, providing basic protective performance for daily use. It also supports customized printing, allowing brands to choose content such as brand names, collection themes, or short slogans according to their needs, enhancing brand recognition and identity expression.

The printing design will change with the variation of ultraviolet rays. When ultraviolet lights intensify, the color of the printed words or patterns on the  tape will become brighter. When ultraviolet light weakens, the color will fade. It turns invisible ultraviolet rays into visible  signals, providing users with intuitive environmental feedback and a more engaging visual experience.
