BP-8178-B

Laboratory 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 shear forces, inflated by compressed air, cooled by a wind ring, and pulled at variable speeds to obtain a double-folded plastic film.
