The 2 layer co-extrusion pe film blowing machine is composed in two extruders and auxiliary parts, the die head and wind-cooling ring can rotate continuously. It can be used for blowing with high and low density polyethylene(HDPE,LDPE), linear low density polyethylene(LLDPE), metallocene polyethylene, etc. through the extrusion die head to form two-layer complex composite film. With greatly improving the physical properties of the films and an increase of strength, so that the films featured in good obstruct properties and air tightness. If the layers are using different colors, the performance and preservation capabilities of the film can be improved.
This kind film is widely used in the liquid film, pearl film, composite-based film, heat shrinkable film, tire separation membrane, anti-aging multi-functional film, anti-jamming membrane, impermeable film, stretch film, cable film,etc.
