RBEW3B Three-layer Coextrusion Extra Film Width Packaging Blown Film Line

The RBEW Three-layer Coextrusion Extra Film Width Packaging Blown Film Line uses the latest technology of coextrusion and new design oscillating haul-off.


  • Air Exhausted type extrusion systems. The heat is exhausted out of the factory by using an air extraction cooling method. No effect to the ambient temperature around the bubble.
  • Central feeding die head in low height shorten melt flow path and reduce the residence time of the melt as it goes through the extrusion system.
  • Temperature controlling automatic air ring with high precision is easy to maintain. It reduces the film thickness tolerance by at least 30%.
  • Silicone bubble cage with anti-sticking foam rollers. No scratch to the film surface.
  • High strength vertical oscillating haul-off unit for over wide film.
  • Winder combining with three kinds of winding modes (contact, central and gap winding modes).

The application of a number of advanced technologies can greatly improve the productivity, making the film thickness more uniform, reducing the energy consumption and creating more value for users.
