3-7 Layers Co-Extrusion Film Blowing Machine
A 3-7 Layers Co-Extrusion Film Blowing Machine is an advanced industrial production line used to manufacture multi-layered plastic films by simultaneously extruding and combining three to seven distinct polymer layers into a single, high-performance film bubble, which is then cooled and flattened to create rolls of film.
