China Multi-wire Kraftliner&Duplex Paper Mill Machinery manufacturers and suppliers

Multi-wire Kraftliner&Duplex Paper Mill Machinery

short description:

Multi-wire Kraftliner&Duplex Paper Mill Machinery uses old cartons(OCC) as bottom pulp and Cellulose as top pulp to produce 100-250 g/m² Kraftliner paper or White top Duplex paper.The Multi-wire Kraftliner&Duplex Paper Mill Machinery has advanced technology, high production efficiency and good output paper quality. It is large-scale capacity,high-speed and double wire,triple wire,even Five wire design,adopts multi-headbox for starching different layers, uniform pulp distribution to achieve small difference in GSM of paper web; the forming wire cooperates with the dewatering units to form a wet paper web, to make sure the paper has a good tensile force.
