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.
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.
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.
The drying process may increase the AA content in the preform up to 3-4 ppm. This is normally due to shearing or friction in the Injection Moulding Machines (IMM) screw and thermal degradation of the resin due to high temperature.
It is possible to control final AA content at each step of the production process:
The circular economy fulfils the needs of human kind preserving the natural resources of the Earth. Recycling is one of the practices the packaging industry, or plastic manufacturers in general, may use to achieve such targets keeping the imperative of the highest level of quality in applications such as food or pharmaceutical to a minimum. Inspecta is the best instrument to guarantee such a level of quality by making the best use of recycled material. It can be used by the producer of recycled regrind raw material to ensure the quality of supply to their own partners.
