Highly efficient, low-cost film production is achieved through a continuous process of melt extrusion - blowing - and multi-stage cooling. The core of the process lies in the precise control of blowing ratio, traction ratio and cooling airflow parameters to solve the challenges of high temperature stability, bubble control and thickness uniformity. In the future, the integration of intelligent control and green manufacturing technology will further promote the application of this process in new energy, semiconductor and other high-end fields.
