CHSJ-50/65 ABA Three Layers Co-extrusion FilmBlown Machine adopts special co-extrusion A+B+A film blowing die and has uniquefeatures in the production of HDPE, LDPE and LLDPE material. The physical strength of the film is enhancedthrough multiple-layer  It can blow films with new materials as wellas reworked plastics with stable performance and reliable quality. This machineset applies a extruder with a special screw structure; advanced screw die head,flexible colling wind ring, and reasonable fixed iris structure can ensure agood proportion of 3 mixed polyethylene materials.  It is wrong to think that the three-layerco-extrusion machine will result in huge power consumption.  The three-layer co-extrusion machine onlyneeds two hosts: one is for the inner layer and the outer layer (A layer) andthe other is for the interlayer (B layer).  Feature:   Reduce the electricity consumption of each ton of film-the maximum energy saving can be 200 kwh/ton Increase the efficiency of production per unit time. Cut the raw material cost and improve the product quality. The cylinder and screw of this extruder are made of superior alloy steel through nitrogen treatment and precision finishing with the optimal hardness and corrosion resistance. Scientifically designed, this kind of screw has many advantages like high production capacity and plasticization. This machine set is used to blow low-density polyethylene (LDPE) and linear low density polyethylene (LLDPE) plastic film to produce various food and clothing packaging bags, garbage bags and vest bags for civil and industrial packaging uses.  Service;  1.Free installation and ajustment.(for consumers purchase more than $100000 only) 2.5 year free after-sales service(No charge for changing parts) and mechanical parts lifetime warranty. 3.We will offer you the professional answers about the relating machines in 24 hours.
