Abstract
The invention relates to a method by which a starting material for injection molding having a viscosity of between 0.50 and 0.7 dL/g is produced from a recycled post-consumer PET having a viscosity of between 0.72 and 0.86 dL/g according to ASTM D4603 and a copolymer fraction of at most approximately 3%, adding a low-viscosity PET material. In the method, the comminuted and dried PET material is melted and decontaminated to such a degree that it is suitable for applications in the food sector and the consumer goods sector.
