Due to availability and properties, PET bottle flakes have manifold applications. The largest amount is used for the production of fibres, filaments and nonwovens. Adding PET flakes when recycling production waste is a possibility to increase the viscosity of the rPET pellets. Finest melt filtration is available; use of up to 100 % rPET pellets possible. | Due to availability and properties, PET bottle flakes have manifold applications.

PET flakes (of sheet, bottles, preforms) can be pelletised or processed directly inline on a sheet line that produces PET sheet with up to 100 % recycled content. In case of inline application a predrying unit (with or without vacuum) can be installed before the sheet extruder (viscoSHEET) instead of a conventional dryer. In this step, post-consumer material is decontaminated for direct food-contact applications and IV maintained or increased. The combination of recycling step and production step results in a competitive investment costs and helps to reduce energy consumption and maintenance while remaining user-friendly. | PET flakes (of sheet, bottles, preforms) can be pelletised or processed directly inline on a sheet line that produces PET sheet with up to 100 % recycled content.

PET flakes are also a valuable secondary resource for strapping bands, which can be made from up to 100 % recycling PET (rPET). In order to meet the high intrinsic viscosity (IV) required, the material undergoes a solid state polycondensation (SSP) process with the Starlinger iV+ technology. | PET flakes are also a valuable secondary resource for strapping bands, which can be made from up to 100% recycling PET (rPET).

In all cases, recoSTAR PET (iV+) offers a competitive solution for superior rPET quality and high reuse rate. | In all cases, recoSTAR PET (iV+) offers a competitive solution for superior rPET quality and high reuse rate. | ||

In case of inline application a vacuum SSP reactor (deCON, viscoSTAR) can be installed before the production extruder instead of a conventional dryer. In this step, post-consumer sheet flakes – or also a mixture of flakes from preforms and post-consumer bottles – are dried, decontaminated and their IV increased before being processed on the production line. The higher IV of the final sheet leads to better and faster processing of the material in thermoforming machines with fewer brittle cups or trays. | In case of inline application a vacuum SSP reactor (deCON, viscoSTAR) can be installed before the production extruder instead of a conventional dryer.
