Less material consumption and the quality of product is steady. It has the following characteristics compared with the traditional process a. gorgeous color, good fastness b. Blowing and printing at the same time. Correct overprint c. conveninet maintenance, stable and reliable quality d. Less power consumption, less labor, work time saving, less cost 2.Advanced structure, simple operation, correct chromatography, convenient maintenance 3.Widely use, several purposes serving (It can blow HDPE and LDPE with  blowing and printing at same time, also can single blowing or single printing) Film Blowing Process: Feeding→plastifying→extruding→blowing out and extensing →cooling and finalizing the design→traction→ corona treatment → printing → Drying → traction →rewinding Feeding Process Just the equipment start, put litter material , Until the material is extruded, ensure the machine head is normal and the condition of plastifying is good, then add large quantities of materia. Plastifying process 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 from the screw pole extrudeding out section, which makes the swirl material turn into the advection by the filter screen in the equipment head.Then ,the materialgoes into the spiral machine head and flows into the die opening.At the last it gets into the film tube and extruded out.  The main processes are the extruding out and the lengthways drafting to control the size of film well just the filming tube is drafted out.  Under the certain extruding machine rotating, the instant temperature and the changeless material discharging, the size (width of breadth ) is decided by the ratio of blowing out, which (the times of film’s transversed drafting ) is 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 Cooling vane（air ring） and air pressure  decide The final main design . Its function is to make the film tube extrude out from die opening and the plastics cooled according to the designed shape and it is adjusted in fine. Section shape and brightness surface are more precise. After the shaped, the material passes the drafting roll and comes into printing part. Printing part The technical flowing process, traction roller→electronic friction machine→first overprint→dry→second overprint →the same speed roller traction rewind. The electric compact machine to treat the film  In this machine, the electronic friction machine is adopted to use the high frequency pulse high voltage and make the air bring ionization and the discharge phenomena. The plastic film passes through the electric discharge space and bears the pulse arc stroke, then the original smooth surface of film forms the pores which can be seen by the naked eye. So the printing fastness can be improved. Printing speed adjustment The motor is electrically moment motor, which uses 200~1200 rotates/min. The worm wheel and worm make the printing plate and roller rotating at the same speed (when worm wheel and worm is slow down the rate largely it can lock itself). Through the mechnism driving, the printing speed is optional ,and can be adjusted between 8~40 meter/min. Drying part Between the front chromatography and the back chromatography the oven drying is used to ensure the ink drying good quality. The time of ink drying effects the quality of products directly. Printing roll, ink scraping and gravure processes        When printing roll was rolled in the ink channel, the whole cylinder is painted with thicker ink and then you can use the machine scraper, the scraper removes the thicker ink in printing chart. So, some surface of roll becomes blank and the depressed part is filled fully with ink and then under the press roll pressure, the ink at the depressed part (pattern) is transferred and printed to the surface of film. Rewinding part This machine adopts double friction rewinders and cutting device. According to customers’ requirements, It could produce the single layer film and double layers rounded film. It could double rewind in single layer or single rewind in two layers. Finally,The film should be rewinded smoothly.   ♦ Our factory has established more than 30 years and always make the market requirements as our guider, the scarification of the clients as our rule, the self-innovation as our develop method, the improvement of our competitive power as our target. ♦ Warmly welcome new and old clients from home and abroad to visit our factory and establish friendly and cooperative business relationship.
