Recycle PET Processing

PET Processors, L.L.C. (PPLLC) has been a leader in recycling PET since 1987.

PPLLC has equipment that is used to convert recycled PET flake into pellets. PPLLC’s capabilities include drying, extruding, and underwater pelletizing flake to provide a pellet feedstock for further processing. Feedstocks are also provided to PPLLC from other sources either post-consumer or post-industrial, typically in the form of pellets. Either source of pellets can be introduced into Rotary Vacuum Dryers to crystallize or increase the molecular weight by solid state polymerizing. Complete material handling systems are in place to provide the highest quality polymer to film, strapping, container, and engineering plastic or other applications.

In the post-consumer area, PPLLC buys recycle PET flake that is free of other polymer types. In the post-industrial area, PPLLC processes clean, ground bottles or preforms, or contaminant-free film scrap. In either case, PPLLC employs heat under vacuum to dry flakes and remove residual impurities.
