100% optical opacity — zero light leakage for displays, optics, stage & photo.
Light-blocking cloth tape serves two audiences: display / optical engineers who need zero light leakage in LCD and camera modules, and stage / film / photography crews who need a true blackout, non-reflective tape.
Yijiayi light-blocking tape offers 100% optical opacity, an ultra-thin profile and an anti-fraying die-cut edge — the technical labels buyers look for.
