In the processing process of the film blower, if the processing process is controlled, the quality controlled plastic bag products must be controlled in place. Under normal circumstances, the processing process of the plastic film machine is divided into feed heating, traction, and controlling the pressure. After the membrane head blowing the air pores, the gas is added to the middle of the round membrane, the membrane is straight up, and the size of the plastic bag is controlled by the amount of gas blowing, and then the membrane stabilizes the membrane. The thickness is controlled by the host and the traction speed. This can be understood. The faster the host speed, the faster the feeding speed, the membrane is thick, and the traction is just the opposite. The faster you pull, the thinner the film. This is the most important link.
To achieve the blowing of the vertical and vertical tension of the blowing, it is necessary to reach a certain percentage of the bonus than BUR and the traction than DDR. If the proportional disorders will cause the horizontal tensile power to decrease. If the existing mold and discounts are stable, the BUR is not a problem. If the foaming is unstable Oral gap/(thin film thickness × BUR)
To reduce the DDR, you need to reduce the gap between the mold port. Reducing the BUR will only make the DDR larger. If the membrane sway is unstable when the membrane blows, it means that the membrane head is too small, and you can use a fixed frame to stabilize the membrane.
