Recycled post-consumer PET flakes are often of sub-optimal quality for the productive process. To address this problem, Plastic Systems, based in Borgoricco (Padua, Italy), has developed a vibrating fluidized bed system that makes it possible to remove residual fine dust and impurities, dry/crystallize the material in a shorter time, and purify the recycled PET through post-condensers.
Thanks to this system a lower viscosity loss and a higher degassing rate take place during sheet extrusion.
