POF is the meaning of the name is shrink film, multilayer coextruded polyolefin heat shrinkable film. Adopting advanced bidirectional tensile three-layer Jung melt extrusion of special process of POF heat shrinkable film, the production of shrink film has high transparency, high shrinkage rate, high heat sealing performance, high toughness, antistatic, excellent cold resistance characteristics, is a safe and reliable soft shrink film. And POF is the most widely used in the world, the development of new environmentally friendly shrink film.

POF is the linear low density polyethylene as the middle layer, polypropylene as inner and outer, through three sets of extrusion plastic extruder, and the die molding, film bubble blowing expansion and other special processing and.

POF production process, mainly through the process of temperature field, and force field control to adjust the product's optical and thermal sealing performance index. POF production is a low-temperature cold way stretching process, the process requires low temperature tensile, so the device should not be too large. The device is too large, the foam stability is poor, the temperature control is higher, the tensile speed is also slow, the product quality will be significantly decreased. The small devices and increase the productivity of extrusion and the posterior segment drawing speed is improved, the foam stability performance is good, low temperature control, tensile speed, product quality can be doubled, the use of such equipment production, equipment is properly chosen, process control, production capacity of not less than large equipment, and contraction of the quality properties of the film.
