Introduction
The EVA/POE solar encapsulation film production line is a critical piece of equipment in photovoltaic module manufacturing, primarily used to produce ethylene-vinyl acetate (EVA) and polyolefin elastomer (POE) encapsulation films. These films protect solar cells, enhance light transmittance, and provide adhesion for lamination in solar panels. The production process typically includes raw material mixing, melt extrusion, casting, cooling and traction, thickness measurement and adjustment, surface treatment, and winding. An automated control system ensures uniform film thickness, defect-free quality, and compliance with high light transmittance, low moisture permeability, and UV resistance requirements. Advanced production lines may also incorporate online inspection, dust removal, purification, and intelligent slitting functions to accommodate different photovoltaic module specifications, improving production efficiency and product reliability. Ultimately, this ensures the long-term durability and power generation efficiency of solar modules.

Our Advantages
Automatic gravimetric feeding system makes sure variety of solid, liquid additives and raw materials high-precision feeding. Tension control system ensure the flexible sheets conveying placidly during cooling , pulling and winding process.The on-line thickness measuring and defect inspecting system can provide real-time feedback of the produc tion quality of EVA/POE solar film. EVA/POE photovoltaic film is mainly used in the encapsulation of photovoltaic modules and is the key material of photovoltaic modules; it can also be used in various industries such as architectural glass curtain wall, automotive glass, hot melt adhesive, etc.
