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 20CrMnTi alloy steel and the screw &cylinder made of nitrided 38CrMoA1A alloy steel adopts automatic temperature control system to adjust melting temperature.
Width of coating & laminating can be regulated, and stepless speed regulation is to control coating thickness and laminating speed, 6stations for material feeding.
The pneumatic-hydraulic edge correction for rewinder assures the accuracy of coating.
Pneumatic roller can assure even pressure.
Automatic counting, edge-blowing, perforating, edge-folding, cutting-off or winding devices are applied.
