Applications
POF three-layer co-extrusion heat shrinkable film blowing machine is used in the production of POF (Polyolefin double-tension three-layer heat-shrinkable film), one of the most advanced eco-friendly plastic packaging materials in the world, which is widely used in the packaging of food, medicine, healthcare products, stationery, cosmetics, handicraft, books, audio products, electric accessories, machinery, and toys.

Features
1. The product of our POF film blowing machine, or POF heat-shrinkable film, made with world-leading technology of Double-Bubble Tube Film Method, is formed by double blow-up. It has the features like being light in weight, high clarity, high flexibility, high shrinkage, and low-temperature resistance.
2. Unique design of PP/PE/PP three-layer co-extrusion die head, together with internal three-layer co-extrusion technology, makes sure that our POF film blowing machine (three-layer co-extrusion heat shrinkable film) has short retention time of flowing channel discharging and uniform distribution of rapid melting materials.
3. The POF film blowing machine (three-layer co-extrusion heat shrinkable film) is equipped with capacitance type thickness gauge system and Gamma ray reflection probe imported from the USA, which greatly reduce the unevenness of the film.
4. For our POF film blowing machine (three-layer co-extrusion heat shrinkable film), we adopt new techniques as water-cooling shaping system, far infrared ray heating system, auto-air recharging system, temperature control of power-adjusting module, rewinding tension control, central rotary rewinding system, and more. The machine can save energy by 15%, comparing to the like products abroad.
