Two-Layer Film Blowing Machine
A Two-Layer Film Blowing Machine is an integrated industrial system used to produce plastic film with two distinct, bonded layers (co-extruded) in a single, continuous process. It uses the blow extrusion (or tubular film) method to inflate a molten plastic tube (bubble), which is then cooled and collapsed to create flat, wide rolls of multilayer film. The primary purpose is to combine the properties of two different polymers into one superior film.
