Double Screw Double Color Film Blowing Machine
A Double Screw Double Color Film Blowing Machine is a specialized industrial plastic processing system that uses two parallel extruders (twin screws) to simultaneously process two different materials or colors of molten plastic. These materials are combined to produce a single, multi-layered tubular film (bubble) through a co-extrusion die, which is then inflated, cooled, and wound into rolls of double-colored or multi-layer plastic film.
