MAKING USE OF THE GOOD ADHESIVE PROPERTY OF POLYPROPYLENE & POLYETHYLENE AT MELTING STATUS, THE MACHINE ADHERES AND LAMINATES PAPER OR COLOR-PRINTED OPP & CPP FILM TO WOVEN BAG UNDER PRESSURE, AND THROUGH CUTTING-OFF AND SEWING TO MAKE PAPER & PLASTIC LAMINATED OR COLOR-PRINTED PACKAGING WOVEN BAGS. IT CAN ALSO DO COATING ON WOVEN BAGS WITH MELTED POLYPROPYLENE & POLYETHYLENE FILM TO MAKE LAMINATED WOVEN BAG.

THE EXTRUDER, WITH HELICAL GEAR REDUCER OF 20 CRMNTI ALLOY STEEL AND THE SCREW % CLINDER MADE OF NITRIDED 38 CRNOA1A ALLOY STEEL ADOPTS AUTOMATIC TEMPERATURE-CONTROL SYSTEM TO ADJUST MELTING TEMPERSTURE. WIDTH OF COATING & LAMINATING CAN BE REGULATED, AND STEPLESS SPEED REGULATION IS TO CONTROL COATING THICKNESS AND LAMINATING SPEED, 6 STATIONS FOR MATERIAL FEEDING. THE PNEUMATIC-HYDRAULIC EDGE CORRECTION FOR REWINDER ASSYRES THE ACCURACY OF COATING. PNEUMATIC ROLLER CAN ASSURE EVEN PRESSURE. AUTOMATIC COUNTING, EDGE-BLOWING, PERFORATING, EDGE-FOLDING, CUTTING-OFF OR WINDING DEVICES ARE APPLIED.
