The 3 layers film blowing line is composed in three extruders and auxiliary parts. It can be used for blowing with HDPE and LDPE,LLDPE, metallocene polyethylene, etc. through the extrusion die head to form three layer complex composite film. With greatly improving the physical properties of the fims and an increase of strength,sothat the films featured in good obstruct properties and air tightness.This thin film barrier properties, thermal insulation, waterproof, anti-frost, oxygen barrier, oil resistance and other excellent, can be widelyused in heavy packing, such as fruit, meat dish, pickles, fresh milk,liquid beverage etc.

Characteristics:
-Using three air ring to start, the cooling effect is better
-Energy saving:30% reduction in energy consumption by best electrical appliances(Brook motor,ETD Inverter,schneider Low voltage electrical appliances)
-Cost saving:high percentage of recycled material or CaCO3 used in the middle layer
-3 extruders to improve output
-Strongest film (strength and durability) thanks to a 3-layer film structure
