In the BOPP (Biaxially Oriented Polypropylene) biaxially oriented film production line, the main function of the melt pump is to pressurize and stabilize the high-temperature plastic melt from the extruder, and then deliver it with a stable flow rate to the extruder die. This significantly enhances the stability of the die pressure, thereby improving the product quality of biaxially oriented films. Additionally, the melt pump achieves a nearly linear output of flow rate, enabling more precise production control.

Furthermore, it can also increase the extrusion volume, thereby enhancing the overall output of the production line. More importantly, the melt pump helps reduce the load on the extruder, conserving energy and lowering production costs.

Therefore, the melt pump is an indispensable equipment in the BOPP biaxially oriented film production line, playing a significant role in improving production efficiency and product quality.
