Optical films including polarizers, light guide plates, brightness enhancement films and diffusion films are coated with nano-level optical layers. Static friction easily absorbs micro dust, causing bright spots and stains on displays, while long-term light exposure leads to delamination and aging. Cut optical film rolls and sheets are fully sealed in our high-shading ESD aluminum foil bags. The bags block 100% visible and ultraviolet light to slow film aging. Premium ESD material eliminates static dust accumulation during slitting and winding. Ultra-low water vapor transmission prevents edge warping caused by moisture. Custom extra-wide bags fit raw material storage for 8.5G and 10.5G high-generation panel lines, supporting long-term dust-free and light-shielded storage and effectively reducing film loss.
Headquartered in Suzhou adjacent to the Yangtze River Delta panel industrial park, our Dongguan base deeply serves the South China optical film cluster, while Chengdu and Hubei bases fully cover emerging display industrial parks in central and western China. The Vietnam factory undertakes cross-border orders, and offices in the United States and Singapore provide professional overseas technical docking and after-sales support.
Produced in Class 100 and Class 1000 dust-free workshops, our bags strictly control precipitation residues and avoid oil contamination on optical coatings, reaching the performance level of imported high-end packaging. With a complete product system and multi-base capacity allocation, we stably supply large-size film roll bags for optoelectronics, semiconductors, automotive electronics and medical precision components with zero supply interruption risks.
