Problems solved by technology

[0002] Polyolefin elastomer film (POE film) is gradually replacing ethylene-vinyl acetate copolymer film (EVA film) as the main photovoltaic packaging film due to its excellent water resistance and better anti-PID performance. The commonly used cross-linked POE film requires a high lamination temperature and a long lamination time, which increases the energy consumption and cost of photovoltaic module production and reduces production efficiency, and the existing POE film UV cut-off The performance is poor, and the absorption characteristics of ultraviolet rays need to be improved urgently
