EVA POE Solar Film Extrusion Line adopts the casting process to produce EVA POE solar cell encapsulation film machine. The primary raw material is imported vinyl acetate copolymer EVA POE, and imported plastic additives are added, which are heated, poured, and extruded. The film is not sticky at room temperature, and the cutting operation is convenient. Thermal cross-linking curing and adhesion-enhancing reactions occur after hot pressing, resulting in a permanent bond and seal. It is a new type of thermosetting hot melt adhesive film.
Solar cell adhesive film is used for solar cell encapsulation. After lamination and curing, it is bonded and sealed, which has the functions of high light transmittance, preventing water vapor penetration, high and low-temperature resistance, and anti-ultraviolet light. to ensure the stable and efficient use of battery components, is a durable and reliable packaging material. EVA POE film production line adopts the casting process to produce EVA POE solar cell encapsulation film. EVA and POE can be shared on one production line. EPE film=EVA+POE+EVA, which is a three-layer co-extruded solar film. Compared with single-layer EVA and POE films, it achieves high performance and saves costs.
Compared with EVA laminating machine, the most significant advantage of the POE laminating machine is a low water vapor transmission rate and high volume resistivity, which ensures the safety and long-term aging resistance of components in high temperature and high humidity environments, and ensures long-term use of components. Specifically, the superior performance of POE film over the EVA film machine is that the POE film machine is a copolymer of ethylene and octene, which is a saturated aliphatic chain structure with fewer carbon atoms in the molecular chain, showing good weather resistance and UV aging resistance. It has excellent heat and low-temperature resistance, so POE film has better aging resistance than EVA film machines.
The EVA film production line for photovoltaic cell encapsulation developed is a special energy-saving, high-efficiency, innovative, and cost-effective extrusion production line. It is currently China’s hottest EVA film extrusion line for photovoltaic cells. Production equipment.
The EVA photovoltaic film under the EVA POE solar film production line generally requires a thermal shrinkage rate of less than 5% to meet the requirements of battery packaging. Shrinkage limits traditional EVA photovoltaic film extrusion production equipment. Production speed is almost entirely dependent on the extrusion speed of the melt out of the die, resulting in an inability to increase production speed. A breakthrough was made in the high-speed extrusion technology of low-shrinkage EVA photovoltaic film. The developed stress relief device can effectively eliminate the residual stress generated during film stretching and online production, and better solve the problem of thermal shrinkage of EVA film.
The EVA POE solar film extrusion line has undergone several iterations. The structure and debugging process of EVA solar film machines have been polished for decades, forming a mature production system in the photovoltaic industry. China Plastic Extruder Supplier GWELL can provide customers with a full range of customized services for EVA solar film production lines from raw material procurement, formulation consultation, related auxiliary equipment matching, debugging process training, etc.

The EVA film production line adopts the casting process to produce EVA solar cell encapsulation film. EVA solar cell film is used for solar cell encapsulation. After the lamination is cured, it is laminated and sealed, which has high light transmittance to the battery components and prevents the penetration of water vapor. , high and low-temperature resistance, anti-ultraviolet, and other functions, to ensure the stable and efficient use of battery components, is a durable and reliable packaging material. EVA packaging film production line is in a monopoly global leading position.
In addition to the characteristics of EVA film, the biggest advantages of the POE film produced are low water vapor transmission rate and high volume resistivity, which ensures the safety and long-term aging resistance of the module under high temperature and high humidity environment. Can be used longer than EVA film. Therefore, the performance of POE film is better than that of EVA film.
POE can replace rubber, flexible PVC, EPDM, EPR, EMA, EVA, TPV, SBC, and LDPE, and other materials, used in different products, such as automotive baffles, flexible conduits, conveyor belts, printing cylinders, sports shoes, wire and cable, auto parts, durable goods, extrusion parts, compression molding parts, sealing materials, pipe fittings and fabric coatings, etc., can also be used as a low-temperature impact modifier to improve the low-temperature impact resistance of PP, and can also be used as a low-temperature impact modifier. It is used in the automotive field as a thermoplastic elastomer.
POE can be processed and formed using common thermoplastic processing equipment. The forming processing temperature and processing pressure should generally be slightly higher and can be processed at extremely high processing speeds. It can be injection molded, extruded, or processed into a sheet or film by a calendar, and can be blow molded, and thermoforming can be used to manufacture products with complex shapes. Various pigments can be added to make different colors as needed.
EVA/POE/EVA film has three layers, including EVA and POE film advantages and lower cost than POE film.
EVA photovoltaic film is different from other EVA products and puts forward higher requirements for raw materials, processes and equipment.
One of the biggest characteristics of EVA raw materials is that it is very sensitive to temperature. When the resin is plasticized in the screw, if the temperature is too high or the temperature is too low, the products will be scrapped immediately. The precise control of temperature will directly affect the upper limit of quality of the final product. For this, GWELL Machinery has designed a special screw for EVA, so that EVA can be completely plasticized during the plasticizing process, and there will be no over-plasticization caused by local over-temperature. Not only the temperature is very important in the yield rate of the product, but also the speed of the production line is extremely important. Ten years ago, the EVA photovoltaic film could not have a very high line speed. At that time, the line speed was only 2 meters per meter. In about seconds, after continuous optimization, the speed of the production line has now reached an astonishing 16m/min. It can be said that it is not inferior to the tens of millions of equipment in Germany. This is also an important reason why GWELL has gradually become the leading company in this market in the past ten years.
Don’t underestimate the influence of the internal stress of EVA photovoltaic film on the quality of photovoltaic film. EVA photovoltaic film is in the hands of downstream module manufacturers. If a film is bulged, the entire module will be scrapped, which is undoubtedly very heavy for module manufacturers. The second reason for this phenomenon is that The internal long force of the EVA film is too large, resulting in excessive stretching. There are strict requirements for the winding tension control of the equipment. The winder of GWELL machinery can strictly control the tension of the product within 20N, which ensures the yield of the product. At the same time, the functions realized by the fully automatic winder developed by GWELL can minimize the waste of products.
EPE=EVA+POE+EVA is a three-layer co-extruded solar film. Compared with single-layer EVA and POE films, it achieves high performance and saves costs.
