Poor Light Blocking Ruining LCD Screens? Guangdayuan's PE Black and White Film Stops Leaks

Pinpoint light leaks in PE black and white film can destroy expensive LCD screens during production. These tiny light spot allow backlight bleed, causing visible defects and complete panel rejection. Manufacturers of photoelectric displays, automotive instrument clusters, and home appliance control panels face high scrap rates when using low-density or unevenly coated films.

Guangdayuan solves this with advanced three-layer co-extrusion technology. Our PE black and white film achieves 99.9% light blocking by using high-density black layers and reflective white layers. Produced under ISO9001 standards with raw materials from Toray and Toyobo, every roll undergoes strict pinhole inspection to ensure zero light transmission.

Our product line includes PE white film, PE electrostatic film, PE antistatic protective film, and PE blue protective film. These serve consumer electronics, photovoltaic modules, building hardware, and medical devices. For LCD protection during shipping and assembly, our PE black and white film delivers unmatched light-blocking reliability.
