Performance and Characteristics
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 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 38CrMoAlA alloy steel adopts automatic temperature control system to adjust melting temperature. Width of coating & laminating can be regulated, and step-less speed regulation is to control coating thickness and laminating speed, 6 stations for material feeding. The pneumatic-hydraulic edge correction for rewinder assures the accuracy of coating. Pneumatic roller can assure even pressure. Edge-blowing, edge-correction and winding devices are applied.
