Process principle: The granules produced by the granulator are transported to the machine, where they are heated and forcefully pushed by the screw, Raise the temperature of the raw material and extrude it together with the melted PE material into a "T" - shaped die to form a three-layer composite sheet material, Stretching by a casting roller, adjusting the product thickness by controlling the speed, and then cooling and shaping by a cooling wheel set, After flattening, appearance inspection, thickness inspection, and static elimination, cut off the ear materials on both sides and proceed with Roll up is the finished product of environmentally friendly paper-based paper. Structural features: It consists of an extruder, T-shaped die head, casting roller, stretching mechanism, thickness gauge, trimming and winding machine and other mechanisms. Production capacity: 200-400kg/h, 1200-2400 tons/year.
