Plastic PE 2 Layer Coextruder Film Blowing Machine (SJT35-FL1400)
The film blowing machine suitable for blowing high density polyethylene HDPE, low-polyethylene LDPE, and linearity low-density polyethylene LLDPE plastic layer film which function is good deaden oxygen, kept out of sun, leakage-proof, kept dry, antifreezing ect so that the goods has been packing can maintain frech while the layers film keeps out things for long time. This kind film widly uses for liquid packing.
1. The main film blowing extruder makes up with 2 extruder, 2 piece screws and barrel and 1 die head, can put 2 different material into the loader to blow the film in the same time. Used the die head rotates which will let the film smoothly and goods quality.
2. Screw and barrel adopt 38CRMOALA, with nitrogen treatment and best rigidity, then the screw has been being high hardness, hard chromium, well corosion preventive, structural durabilities.
3. The die head plates hard chromium which the structure is as screw Mandrel while extrudes can melt the granule uniformly, the surface of the blown film looks clearly and well. The air ring structure use as labyrinth so that the outlet air is uniform.
4. The winder unit adopts pressure friction rewinder, or rewinder with center winder by torque motor, rewinder with bouble friction roller or bouble center rewinder which uses the torque motor for adjusting winder so that the film while rewinder will be smooth and easy take out and change the roller film.
