GETEC Laboratory releases new analyses methodologies for better quality control of recycled PET packaging and textiles

GETEC Laboratory has introduced new methodologies for measuring the particle size distribution of solid particles in PET and non-volatile NIAS using appropriate chemical analysis techniques.

• For optimal food safety in rPET packaging, it's essential to detect NIAS to ensure rPET purity. Detecting non-volatile NIAS can be more challenging compared to volatile NIAS. GETEC Laboratory has created a new dissolution-precipitation analysis method using Liquid Chromatography to identify non-volatile NIAS in rPET. This method detects four to six times more non-volatile NIAS than our in-house extraction method.
• For optimal yarn quality in rPET-based textiles, GETEC's innovative Partisol analysis measures the particle size distribution of solid contaminants in PET. Post-consumer recycled PET flakes and pellets often contain up to 113,000 and 20,000 particles respectively, with sizes ranging from 1 to 100 micrometers. Higher solid content in rPET increases the likelihood of filament breakage during melt spinning. The Partisol provides insights into which rPET feedstocks could lead to more or less filament breakage, potentially preventing unexpected production losses and reducing costs. Additionally, it can enhance the mechanical properties of the yarn.
