GETEC.PARK EMMEN (GPE) releases new White Paper: “New insights to improve the recycled PET product quality control.”

Therefore, cost-effective processing and obtaining the right and safe recycled PET quality is essential for both PET recyclers, PET packaging manufacturers and brand owners. Chemical analysis techniques are vital to monitor and control the quality of the (recycled) PET polymers and packaging. It contributes to improve product safety risks and saving costs.

The White Paper explains in-depth how:

• Melting steps during PET recycling can give rise to the occurrence of relevant NIAS. Using Headspace Gas Chromatography (GC), such substances can be detected accurately. In this way, the rPET purity can be monitored. Recommendations are given to improve the purity of recycled PET.
• The presence of solid particle contaminants arising in rPET can be detected by the unique GPE Partisol analysis. It is shown that the haze in PET packaging increases linearly with the total number of solid particles in PET. In addition, over 70% of the detected solid particles are 1 – 3 µm in size. Recommendations are given to minimize the presence of solid particles in PET to improve the PET transparency and minimize the crystallization behaviour.
