Inspecta for utmost preform quality

Inspecta is the result of Piovan’s commitment to continuous improvement.

After many years of fruitful market presence helping the producers of PET preforms, Medical Plastic Solutions and Packaging for food, acetaldehyde PETes Analyzer has evolved into Inspecta: a precise, reliable and user friendly analyser for detecting the presence of volatile substances inside PET and rPET preforms, sheets and granules.

Benefits

  • Constant process control
  • High levels of accuracy, duplication and replication
  • Ease of use
  • Increase of sampling frequency for preforms and PET sheets analysis
  • Up to 70% cost and time reductions

When a high quality, pure and repetitive production process is requested, Inspecta helps in proving the absence of unintentionally added substances with a close control.

With Inspecta, the analysis is automatic: its software manages all the main functions and settings, operates the instrument, calculates calibration curves and it produces a detailed and clear report that summarises all relevant data and working parameters. This allows the line operators to directly perform the examination process.

Inspecta can be installed close to the production area, with no need for sample collection and transport to a laboratory. The analysis gets aligned to the production timing, allowing for real time results and prompt corrective actions, if needed, with concrete cost savings.

Inspecta in drying process

Acetaldehyde (AA) is a typical example of undesired substance in PET production, but it is not the only one.
It is a colourless volatile with a fruity smell which arises as a by-product of PET thermal degradation by oxidation of the vinyl end group of the polymer chain.

In PET bottles, AA is usually present at a few ppm concentration, which is slowly desorbed into the bottle content, altering its taste and aroma.
