Mature Technology BOPP Film Production Line With Adjustable Ratio Of Bidirectional Stretching Function
Product Description
Extruder
Twin screw extruder is equipped with two vacuum ports to realize vacuum dehumidification, instead of installing dryer in traditional production process.
The molten particles establish a stable pressure through the metering pump, and then enter the filter to be filtered. The latest process requires the polyester to adopt a disc filter screen, which is conducive to the melt staying in the filter for as long as possible during the process of passing through the filter, so as to enhance the consistency of the melt. The heating of the filter should be very uniform to avoid so-called hot spots. To achieve this effect, use hot oil heating.
The production of biaxially oriented polyester film requires stable extrusion quantity of extruder, small fluctuation range of outlet pressure, no overheating and degradation of melt, so as to achieve high quality of film products. This requires uniform extrusion, melt temperature and plasticization, elimination of bubbles, no pulsation of material flow and low power consumption.
