PVA Optical Film Market Sees Major Capacity Expansion and Technological Shifts
AsiaMB Special Report – The global PVA optical film sector is undergoing significant transformation as industry leader Kuraray announces a major production expansion in Japan while Chinese manufacturers make technological breakthroughs.
The Japanese chemical giant revealed plans to invest in new production lines at its Saijo plant in Ehime Prefecture, targeting the booming large-format display panel market. Scheduled for completion by late 2027, the expansion will add 38 million square meters of annual capacity, pushing Kuraray’s global output beyond 330 million square meters.
“Demand for wider PVA films has surged alongside the trend toward larger television and monitor displays,” noted a Kuraray spokesperson. The company currently dominates the high-barrier PVA optical film market, holding over 70% global share through its integrated production capabilities from raw PVA to finished film.
Meanwhile, China’s Wanwei High-Tech has achieved a technological milestone through its collaboration with the University of Science and Technology of China. The company has successfully developed 3.4-meter wide PVA optical films now being used in large LCD panels. Its upcoming 20 million square meter TFT-grade production line, expected to launch next year, promises to enhance domestic supply capabilities.
Industry analysts highlight the growing importance of PVA films in the display supply chain. “While China leads in panel manufacturing, upstream materials remain a challenge,” commented an AsiaMB industry expert. “Wanwei’s progress marks an important step in reducing import dependence, though significant gaps with Japanese technology remain.”
The Chinese PVA optical film market, valued at approximately 3.4 billion yuan in 2023, continues to show steady growth potential. Market observers anticipate intensified competition as domestic producers ramp up capacity and improve product quality in the coming years.
