/ 2022Multilayer co-extruded casting film can be divided into several layers
In contrast, the development and application of CPE flow film production line started late, and the foundation of CPE flow film production line is weak.
In order to prevent excessive "neck shrinkage" and edge rolling of CPE flow film plastic melt due to thermal expansion and cold contraction, air knife or electronic edge locking device is installed on both sides of the flow roll. Use compressed air or high pressure ion flow, acting on the plastic film, make it close to the surface of the roll.
