The granules made by the granulator are transferred to the feeding barrel of this equipment, and the materials are feed to the inlet by a quantitative screw, and the temperature of the raw material particles is increased and they are softened to 160 ℃ by electric heating and screw extrusion. Together with the molten PE material, it is extruded into an "O" -shaped die to form a cylindrical material. After being blown up by compressed air, under the action of cold wind and film bubble setting mechanism, a stable stone paper tube is formed. After being cut, it is rolled up into two stone paper rolls at the same time.

After coating the base paper produced by this equipment, the product can be used for writing, printing, and making into books, magazines, notebooks, advertising brochures and other products.
