EVA / POE Solar Film Production Line
Advanced Extrusion System for Photovoltaic Encapsulation Films
The EVA / POE Solar Film Production Line is a state-of-the-art manufacturing system engineered for the high-efficiency production of solar cell encapsulation films using EVA (ethylene vinyl acetate) and POE (polyolefin elastomer) materials. This production line supports the global solar energy industry by delivering films with low shrinkage, excellent optical properties, and high durability - all critical for photovoltaic module performance and long-term reliability.
Solar encapsulation films produced on this line protect sensitive solar cells from moisture, UV exposure, temperature cycles, and mechanical stress; making them indispensable components within modern photovoltaic (PV) panels.
What is Solar Encapsulation Film?
Solar encapsulation film refers to specialized polymer films placed between solar cells and protective glass layers in photovoltaic modules. These films - typically based on EVA or POE - provide adhesion, weather resistance, optical transparency, and long-lasting protection. Effective encapsulation enhances module performance, prevents moisture ingress, and helps maintain PV system efficiency over decades of outdoor use.
Key Features of the EVA / POE Solar Film Production Line
High-Quality Film Extrusion
The production line utilises advanced twin-screw extrusion technology with automatic gravimetric feeding, ensuring uniform compounding of EVA/POE resin and additives such as cross-linking agents, UV absorbers, and coupling agents. Precise material mixing contributes to consistent film quality and performance.
Low Shrinkage and High Transparency
Films produced on the line are engineered to exhibit low shrinkage and high light transmittance - both essential for effective encapsulation. Consistent film thickness and optical properties support reliable lamination outcomes during PV module assembly.
Intelligent and Automated Production
Featuring automated feeding, intelligent control systems, and continuous thickness monitoring, the production line offers precise control and reproducibility. This drives high yields and reduces material waste.
