HDPE (High Density Polyethylene): 0.941 ~ 0.965 Polyethylene as High Density Polyethylene (High Density Polyethylene).HDPE is a high crystallinity and non-polar thermoplastic resin. The appearance of the original HDPE is milky white, with a certain degree of translucent in the small section.PE has excellent characteristics of most life and industrial chemicals. HDPE has good electrical properties, especially the insulation dielectric strength, so that it is suitable for wire and cable.

High density polyethylene was higher than that of low density polyethylene heat resistance and mechanical strength and improved on water and gas barrier property. High density polyethylene can use extruding method processed into tubing, plate, sheet, profile and monofilament, flat wire, packing belt. The injection molding method can produce all kinds of products, daily necessities and industrial supplies.

We have a production process for Plastic Food Bags On Roll.

Gravure web, general use of stepless speed control system printing speed, in order to make the various printing units synchronized, using a main motor and CVT, with a long rotating shaft to drive the entire printing system. Start the ink pump, check whether the ink pump reverse. In the color printing plate clutch out of the situation to start the main motor, check the transmission speed, and then find open dryer and blower, at low speed to close the clutch, the color register. In the first color as the benchmark, starting point of the beginning of the second, third, fourth color of the vertical chromatic registration; then still in the first color as the benchmark, the second, third, fourth color of the horizontal register, the horizontal chromatic with the handwheel fine-tuned alignment. 

The vertical and horizontal color is aligned to speed up printing. If there is no automatic computer to version of the device, then the printing speed whether it is satellite-type Web or modular web, do not exceed 40m/min. More than 40m/min, the naked eye can not follow observation, general control in 25-30m/min can. Operators should pay close attention to the color of the situation, at any time manual adjustment. If there is a fully automatic computer version of the device, then the operation mode should be played on the automatic version, at this time, the computer can automatically track, found deviation, will automatically send the correct signal, so that the plate roll or base material movement, the new alignment.
