M3B-1700Q-C three layer co-extrusion reversing haul-off blown film machine is suitable for the materials such as LDPE,LLDPE,mLLDPE,EVA and HDPE.
Commissioning of new three-layer production line of capacity 250 tons per month with Auto Thickness Controller 9th in Pakistan.
It provides more choice in terms of the application of the materials.Blown film is the most widely used method to produce plastic film.The melt material plasticized by the extruders go through the screen changer and perforated plate, then becomes cylindrical billet pressed by the die head.
At this time, compressed air is pumped into the billet,thus it is inflated into bubble.The volume of the compressed air controls the horizontal size and lay flat of the bubble.The inflated bubble goes through the air ring which cools the bubble, sizing cage and collapsing unit, next goes into the haul off roller.
During the above procedure, the bubble is stabilized, folded and pressed.In the end, the film is rolled up by the winder. it is widely used in food, costume, the package of industrial produces, daily products for various packing bag, hand bag and trash bag. it is the basic materials for printing and compounding.
