The material is HDPE, LDPE, dissoluble plastic, biodegradable material and recycling material. This will be your best choice for production of shopping bags, vest bags and other plastic bags. We will provide you with a whole bag production line, including all kinds of bag making machine. 1. Wide range of applications, there are several purposes (It can blow HDPE and LDPE, simultaneously blowing and printing or single blowing or single printing) 2.Advanced structure, easy operation, correct overprint, easy maintenance 3. Saving raw materials, reliable quality. It has the following characteristics compared to traditional wheel printer a. Bright color, more fastness b. Blow and color-print at same time, correct chromatography  c. Simple maintenance, reliable and stable quality  d. Less power consumption, saving labor, less work time , less cost Step of the Film Blowing: Feeding→plastifying→extruding→blowing out and extensing →cooling and finalizing the design→traction→ corona treatment → printing → Drying → traction →rewinding Feeding Process When the equipment just start, we should put litter material. Until the material is extruded, the machine head is normal and the condition of plastifying is good , then add large quantities of material. Plastifying process The raw material goes out from the extruder and it is heated through preheat section, plastifying section and extruding out measurement section. It mixed by screw pole and the grain material is plastified into fused mass.  The Extruding out process The fused material output from the screw pole extruding out section makes the original swirl material becoming the advection through the filter screen in machine head. Then, the material comes into the spiral machine head and flows into the die opening, finally, it becomes the cylinder filming tube, 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 thickness of film is decided by the lengthways drafting time, i.e. The ratio between drafting speed and the extruding speed and normally 3~7 times. If the drafting ratio is too large, the film can easily broke out. Cooling and finalizing the design The design finalizing is mainly decided by cooling vane（air ring） by air pressure and its function is to make the film tube extrude out from die opening. The plastic is cooled according the designed shape. It is adjusted in fine which makes the more precision section shape and brightness surface . After shaping, the material passes the drafting roll and comes into printing part. Printing part The technical flowing process following, 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, make the air bring ionization and the discharge phenomena. When the plastic film passes through the electric discharge space and bears the pulse arc stroke, 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 the slowdown of the worm wheel and worm is large it can lock itself). Through the mechnism driving, the printing speed can be adjusted between 8~40 meter/min, at your optional. 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, then you can use the machine scraper, the scraper removes the thicker ink in printing chart. So that  some surface of roll becomes blank and the depressed part is  fulled with ink, 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 with cutting device and it could produce the single layer film and double layers rounded film according to customers’ requirements. It could be double rewind in single layer or single rewind in two layers and 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.
