Characteristics of Gwell EVA film production line: (1) EVA single screw extruder is used for extrusion, and the barrel constant temperature circulating water cooling system solves the technical difficulties of EVA plasticizing and non-crosslinking. (2) Double-sided embossing is adopted for the roller body, and technical difficulties of adhesive roller are solved. (3) The cooling part adopts the cooling roller and the stress relief cold bed to make the film run smoothly and fully finalize the design, ensuring the shrinkage rate is less than 3%. (4) The whole line adopts PLC automatic control to realize man-machine interface operation. (5) The production line is equipped with online quality monitoring and control system to ensure the product qualification rate. (6) Patented micro-tension winding machine, the line speed of the whole production line can reach 14m/min
