PP PE PLA HDPE LDPE plastic polymer nylon automatic monolayer lab small blow film machine
The small blow film machine consisted of single screw extruder and film blowing tower, it is mainly used for testing the film blowing feasibility of polymer materials and the colloid status contained in the materials.
The small blow film machine is refers to the technological process that the double-folded plastic film made by compressed air huffing, vane cooling and frequency conversion traction and the plastic melt being extruded through dies at a certain temperature and certain cutting force.
