High Capacity PP Pet Wrap Belt Extrusion Plant Pet Tape Producing Machine Line

PET strap is recognized a new environment protective strapping material to substitute for Steel Strap &PP Strap in the ruling international market. They are not only the aggregation of the intensity and the tenacity of steel strap, but also overcome the disadvantage of the tradition packing material such as insufficient intensity, brittle and so on. At present, they have been applied in wood, steel and so on.
Adopts advanced dehumidify dryer system. It makes sure the material humidity at 80PPM at 50PPM dew point. Meanwhile, it compact material and increase the viscidity.
Adopts closed cycle transport system after dryer to avoid contact with outside air and make sure the material drying continuously.
Extruder adopts special screw for PET. The screw has unique separate and mix property to make sure uniform plasticizing. The screw is suitable for recycled PET bottle flakes, PET mixture and original PET material. And the extruder adopts ration forced feeding to make sure the stable extruding. It makes sure the product uniform. 
Produce different model product at one die and mould, adopting hydraulic screen exchanger without material leak.
Static cooling roller replaces the water cooling tank. The roller will cool the strap at the constant temperature. It improves the product's stretch intensity.
The strap after formed will be warm and anneal treated to wipe off the part stress remained after stretch. It makes molecule tropism be steady to avoid strap distortion caused by storage.
The winder adopts double work position and auto-meter. It is easy operation and convenient coil change.
Centralized electrical control, PLC self-correcting control make it is easy operate.
