EVA Solar Encapsulation Film
High-performance EVA film designed for long-life, high-efficiency solar PV modules
EVA (Ethylene Vinyl Acetate) Solar Encapsulation Film is a premium-grade polymer film used in the manufacturing of photovoltaic (PV) modules. It acts as a protective encapsulant between the solar cells, front glass, and backsheet—ensuring long-term durability, enhanced safety, and maximum energy output.
Engineered with superior optical clarity and excellent UV/weather resistance, our EVA Film is the ideal choice for modern solar module manufacturers seeking high efficiency and long service life.
