PE Film Blowing Machine

This blown-film extrusion process is used to produce both HDPE and LDPE shrink wraps. The main extruder uses variable frequency drive to enhance stability in speed regulation, which results in 30% electricity reduction. Made of 38CrMoAl, the extruder barrel has been through nitriding to gain a case hardened surface.

Belt carriers of the caterpillar haul-off are adjustable in height. Proper height adjustment allows effective cooling of hot plastic films of various sizes. Plenty of application exist for our PE film blowing machine, such as in the manufacture of laminating film, packing film, mulching film and other packaging films for textile and apparel.

Features
1. The PE film blowing machine uses 2 extruders that force two same or different PE resins into the same extrusion head (die). This process is generally known as co-extrusion. The resultant film has 2 layers with improved physical strength, air tightness and ability to keep out impurities.
2. The rotary extrusion die ensures quality plastic films with good flatness and uniform thickness. Shrink wraps coming out of this extrusion die can meet the quality requirements for further packaging and printing process. A variety of other plastic films can be produced using our rotary extrusion head, such as the pearlised film, laminating film for packaging liquid, insulation film, and multi-purpose mulching film.
3. Optimized screen changer design allows fast change of filtering screen.
4. Other desirable features include the length measurement device, slitter, cooling water drainage system, nip rolls, and trim scraps winding device.
