Making use of the good adhesive property of polypropylene & polyethylene at 
melting status,the machine adheres and laminates film to non woven fabric under 
pressure to make laminated or color-printed packaging nonwoven bags.The 
laminating with melted polypropylene & polyethylene film on the non woven 
surface of them to make the color-printed packaging bags .
The extruder with 
vertical gear reducer adopts automatic temperature-control system to adjust 
melting temperature,the screw and cylinder are made of 38CrMoAlA alloy steel and 
done treatment of nitrogenation.The double-die can realize single or double-face 
coating.width of coating &laminating can be regulated,and stepless speed 
regulation is to control coating thickness and laminating speed.The 
photoelectric meter of edge correcting assures the accuracy of coating.automatic 
edge cutting.counting,edge-blowing,and winding devices are applied
