Product introduction MX-POF series three to five layer co extrusion heat shrink blown film unit features: POF heat shrink blown film unit production line plastic extrusion adopts multi-layer co extrusion (five layer extrusion, three-layer extrusion) form, through blowing down the automatic film tube, sizing the water ring, and then blowing up again. The heating furnace uses imported infrared ceramic plates for heating, and the temperature control system adopts proportional control form. The automatic ambient temperature and temperature control ratio are adjusted to achieve the characteristics of fast heating speed and high temperature control accuracy
