Extrusion blown film refers to the technological process that plastics particles are continuously melted and extruded under a certain temperature and shear force, inflated by compressed air, cooled by vane cooling device, and finally be folded by take-up roller.

This machine is mainly used for testing the film blowing feasibility of polymer materials and the colloid status contained in the materials, as well as the dispersity of colored dispersion, controlled mixture and extrudate.
