Whatever your market requirements are, our super-cleaning technology fulfils the standard. 100% rPET flakes acc. to EFSA infants scenario (beverage and food packaging) and 100% rPET flakes acc. to US FDA guideline (for conditions C-H + J) give you highest flexibility in all markets worldwide. The viscotec deCON unit is the only equipment in the world which – till today – achieved more than 35 Positive Opinions for 100% super-clean rPET flake for direct food contact acc. to EFSA’s infants scenario. Hence, with viscotec equipment you produce rPET mono-layer sheet with 100% post-consumer material one the highest level of reliability and safety. Our outstanding cleaning efficiencies are simply the best in rPET flake recycling. In case of rHDPE for direct food contact, viscotec has the FDA LNO for 50% recycled content acc. to US FDA guideline (for conditions E-G).

  • Dynamic vacuum treatment

    Due to the reduction of the boiling temperature, all contaminants evaporate when reaching the PET surface. As a result, shorter residence times at lower temperatures with an outstanding decontamination performance are achieved with viscotec technology.

  • First in, first out principle

    The design of the viscoSTAR and deCON outlet ensures a constant treatment time of the material in the reactor. This essential and patented treatment is the main element accountable for viscotec's worldwide market success.

Gas chromatographies

Gas chromatographies are used for testing the purity of PET. Constant long-term screenings at customer sites worldwide confirm the excellent cleaning efficiency of the deCON.
