Multi-Layer Blown Film Line
The multi-layer blown film line is equipped with the extruder with force feeding function, precision type ceramic heater, precision type air ring with double vents, horizontally rotary traction system, fully automatic surface friction type winder with double cutting double winding, computer centralized control system as well as other advanced equipment. It has been widely used in manufacture of high transparence packing films.
Different from CWHL model, this blown film line works for double or three layer co-extrusion films. The product is mainly employed for blowing plastic laminated films made of LDPE, HDPE as well as LLDPE, etc. These films have been extensively used as raw materials for packing bags of liquid, printing substrate, export product, industrial product, etc. The co-extrusion blown film has better flexibility, thus able to extend the refreshing time of the packed liquid.
The main machine of the blown film line is characterized by variable frequency control, which not only improves the stability of speed regulation but also saves electricity by 30%. The plastic film blowing machine comes with two sets of screw and barrel, as well as two sets of die head and gear boxes. The screw is constructed from 38CRMOAIA alloy steel with precision machining and nitrogen treatment. Accordingly, it has optimum hardness and can be used durably. The lifting type traction frame can provide films, large or small, with the best cooling effects.
