The Photovoltaic Encapsulant Film Production Line is a complete and integrated system specifically developed for the continuous production of high-quality encapsulation films such as EVA (Ethylene Vinyl Acetate) and POE (Polyolefin Elastomer). These films are essential materials used in the lamination process of solar photovoltaic (PV) modules, providing excellent adhesion, UV resistance, thermal stability, and electrical insulation.
This production line combines high-precision extrusion, casting, cooling, surface treatment, winding, and automatic tension control to ensure film uniformity and stable output. It supports modular customization to meet different film formulations and production capacities.
Film Production Line Features & Advantages
- High precision film thickness control (±5 microns)
- Compatible with EVA, POE, and multilayer EPE structures
- Inline embossing and surface treatment optional
- Automatic tension control for uniform winding
- Supports co-extrusion (e.g., EVA+POE in one film)
- Low gel count and excellent optical clarity
- Customizable for anti-PID, UV cut-off, or fast-cure grades

Products Application
EVA and POE encapsulant films, produced by high-precision film production line, is widely used in solar photovoltaic modules. These films protect solar cells, enhance light transmission, and improve long-term durability. EVA films are ideal for standard modules due to their clarity and adhesion, while POE films offer superior moisture resistance and are preferred for high-performance and bifacial modules.
