PET plastics is the abbreviation of Polyethylene terephthalate in English, referred to as PET or PETP. It is a condensate of terephthalic acid and ethylene glycol. Together with PBT, it is called thermoplastic polyester, or saturated polyester. It is one of the five engineering plastics.

PET can be used to make film sheets, packaging bottles, electronic appliances, automotive accessories, various mechanical equipment such as gears, cams, pump shells, belt pulleys, motor frames and clock parts, also can be used as microwave oven pans, various roofs, outdoor billboards and models. PET has a wide range of uses, covering all aspects of our lives.

In order to produce white transparent and high viscosity, recycled bottle flakes should be pelletized with suitable screw and take full account of the characteristics of PET, which can be sold to bottle blowers for reuse and obtain higher value.

The screw needs high precision to ensure that there is no clearance between threaded components, so that the extruded particles can not appear black spots.

When choosing screw arrangement, attention should be paid to the shear strength of screw.

In order to prevent the high temperature hydrolysis of PET, the drying box should be used to pre-crystallize the PET.
