RTB300 Hot Melt Coating machine is suitable for making the self adhesive label, medicine bandage, tape, shoes material and so on.
B. Main characteristic
RTB300 Hot Melt Coating machine adopts Cantilever Type structure for loading and unloading the material easily and can coat the material up to a width of 400mm. so it is standard and ideal equipment for one-person operation. If it is equipped with the tension controller of magnetic powder, you can obtain high production efficiency.
