3-layer film co-extrusion blowing machine is designed by leader machinery to meet the customer’s evolving demands. All models are equipped with high performing extruder for minimized power consumption. The blown film is effectively cooled from the inside using internal bubble cooling, or IBC for short. Other desirable features in this multilayer blown film line include the 360 degree oscillating haul off, deviation control system, automatic windup rollers, idler rollers for tension adjustment, and computer display.
The high level of flexibility in the process allows the extruder to produce many different widths including 800mm and 1500mm, as well as various thicknesses ranging from 0.01mm-0.1mm. Additionally, a wide selection of raw plastics can be used to produce blown films, such as the LDPE, HDPE, LLDPE, and MLLDPE. Compared with similar equipment, the 3-layer film co-extrusion blowing machine has many benefits including higher productivity, better plasticization, lower energy consumption, and easier operation. The line is completed with automatic winder that provides exceptionally flat roll production. The resultant film is an ideal barrier against moisture, rain, wind, frost, oxygen, and oil. It is therefore widely used in packing fruit, meat, vegetable pickles, fresh milk, and liquid drinks.
