  • Method for processing polyethylene terephthalate
    Patent number: 10343323
    Abstract: The inventions relates to a method for processing polyethylene terephthalate (PET) comprising supplying PET raw material (S1), drying the PET raw material (S4) to a target moisture level, plasticizing the PET (S5), and injecting the plasticized PET (S6) into a mold. In this method, the target moisture level is between 60 ppm and 250 ppm to generate hydrolysis of PET during plasticization (S5) resulting in a controlled drop of intrinsic viscosity of the PET. According to other aspects of the invention, there is provided a method for forming a bottle and a method for packaging still beverage in this bottle.
