Lab Blown Film Machine/PLC Control (3-Layer Co-extrusion)

Extrusion blowing film involves the process of continuously extruding plastic melt through a die under specific temperatures and shearing forces, then inflating it with compressed air, cooling it with a wind ring, and pulling it at variable speeds to obtain a double-folded plastic film.
