3 layer film blowing line

Usage: Film blowingline (3 layer film bowing line)is composed in three extruders and auxiliary parts. 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 three-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. Adopting advanced die head and wind-cooling ring rotation technology, so it can make the film in good uniformity, rolling formation. 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. Features: The line is featured in: 1)360°non-stop rotary die head 2)Mandrel spiral die head made by CNC Machining Center with mirror polishing 3)Co-extrusion central feeding spiral die head 4)Manual high-speed screen changer with melt pressure gauge 5)Back-to-Back two station double winder with auto tension control Detail Technical Parameters: Model SJ-50x3/28-BL1400SJ-50x3/28-BL1600SJ-60x3/28-BL2200Co-extrusion Layers 3 Layers3 Layers3 LayersSuitable Material LDPE, LLDPE, mLLDPEMax.
