Blown film is a popular plastic processing method to produce different films in order to satisfy various needs, generally speaking, it is about heating the material pellets until they melt, then blow it into thin film. By extrusion, the material will turn into the shape of tube, keep it in the state of melt flow, and blow it with compressed air to achieve required thickness, finally cooling it for end product which is thin film. The quality of film depends on the machine and material, our factory adopts advanced technique and equipment which ensure our film product stays at high standard mechanical property, lower the waste to the minimum.
