Use for: EDUCAÇAO FISICA、LDPE、LLDPE、masterbatch, filled masterbatch, plastics additives, functional masterbatch and so on. This mini film blowing machine is suitable to use for laboratory working. Extrusion blown film refers to the plastic melt at a certain temperature, a certain shear force is continuously extruded through a die, blown by compressed air, air cooling and frequency pulling ring obtained double-folding plastic film process. This machine is mainly used to detect the feasibility of blowing film for polymer materials, as well as the dispersion of pigments and masterbatches.
