Blown Film Extrusion is one of the processes to produce plastic film products such as food packaging film, industrial film, agricultural film, medical film, etc. The main polymers materials are LDPE, HDPE, PP, PE. The Extruder Blown Film Die Head is the core component which is called the "HEART" of the Plastic Film Blowing Machine. The main function of Die Head is to distribute the melted polymer evenly so that the thickness measured around the circumference of the tube being produced is uniform. It is the key factor to ensure a quality film.
