Main feature and purpose:


The plastic film products are even more needed by people from day to day with the widely use of package film.


Our factory produce plastic machinery series over 30 years' experience, collect similar machines' characters to produce this machine. The machine is special to blow film with HDPE, LDPE, dissoluble and reproducible plastic..


The advantages make convenient operation and extra fine quality. This machine is compact structure, convenient operation, saving space and it is Intelligent facilities to produce plastic film.


Step of the Film Blowing:


Feeding→plastifying→extruding→blowing out and extensing


→cooling and finalizing the design→traction→ traction →rewinding


Feeding and Plastifying process


Once the equipment start, we should put litter material at first. And until the material is extruded ,make sure the machine head is right and the effect of plastifying is good, and then increase the quantities of material.After the raw material goes out from the extruder and is heated through preheat section, it plasticizes and is extruded out. Then mixed by srew pole, and finally the granular material is plastified into melt. 


The Extruding out process


The fused material output is from the screw pole extruding out section. It makes the original swirl material become the advection through the filter screen in machine head and then the material comes into the spiral machine head and flows into the die opening. Finally it becomes the cylinder filming tube and extruded out. 


The film's size will be controlled well once the film tube is elongated, it has two main processes, blowing out and the lengthways drafting. 


Under the certain extruding machine rotating, the instant temperature and the changeless material discharging, also the dimension (width of breadth ) is decided by the ratio of blowing out and (the times of film’s transversed drafting ) can be easily operated under 3 ~ 6 times. 


The lengthways drafting time decide the thickness of film , i.e. usually, the ratio is 3~7 times between drafting speed and the extruding speed. The film is easily broken out on the condition of the too large drafting ration.


Cooling and finalizing the design


The design finalizing is mainly decided by cooling vane(air ring) and air pressure. Its function is to make the film tube extrude out from die opening and the plastics cooled according the designed shape and it is adjusted in fine. The more precision section shape and brightness surface. After the shaped, the material passes the drafting roll and comes into printing part.


Rewinding part


This machine adopts double friction rewinders with cutting device and it could produce the single layer film and double layers rounded film according to customers’ requirements. It could double rewind in single layer or single rewind in two layers and  the film should be rewinded smoothly.
