The EVA film production line adopts casting technology to produce EVA solar cell packaging film. The main raw material is vinyl acetate copolymer (EVA), which is formed by heating, casting and extruding after adding additives.

Extrusion system Aiming at the processing characteristics of EVA polymer materials, GWELL has made special improvements to the extruder design of the production line. Over the years, it has not only created many technical advantages, but also has a deep understanding of the characteristics of single-screw technology and rich practical experience. Production costs are also reduced. The melt pump imported from Germany ensures that the melt can enter the mold with constant pressure and constant volume. The closed-loop system of the melt pump and the host plays an intelligent role in regulating the stable operation of the entire production line.
The development and utilization of green energy is the hottest topic at present. Solar energy is the most outstanding member of the green energy family. In recent years, the output of global solar power generation products has been growing globally at a rate of more than 45% every year. China’s investment and development in the field of solar energy have exceeded the world’s average level.
The solar cell module is made of tempered glass–EVA film–semiconductor chip–EVA film–battery backplane lamination package. After lamination, it is heated and pressed. During this process, the EVA film will be cross-linked and cured to fix the multi-layer structure together to protect the product while maintaining high light transmittance.
EVA film is a thermosetting and viscous film that can be used for glass interlayer. Due to the superiority of EVA film in terms of adhesion, durability, optical properties, etc., it is more and more widely used in Current components and various optical products.
