Polyethylene terephthalate (PET) and recycled PET Packaging Testing

Physical and chemical laboratory analyses on PET and recycled PET materials to determine their characteristics and composition

Polyethylene terephthalate (PET) and recycled PET (rPET) materials are known for their durability and versatility and are accordingly analysed for many reasons, for example to discover if the material has been previously recycled, and if so, how many times, to confirm its Molecular Weight, and to discover its purity, for example regarding presence of heavy metals

Intertek chemists have years of experience in analyzing PET packaging materials, using a wide range of analytical and physical testing techniques. Our team of experts can support you with troubleshooting, process optimization and problem solving activities regarding the processing of your PET materials.

Our experts achieve insight using an array of techniques such as nuclear magnetic resonance (NMR), GPC, ICP and XRF to determine the composition of materials such as PET, as part of recycled plastics analysis.

Our expert analysis of PET includes the following

• Dilute solution viscosity
• DEG content
• IPA content
• CHDM content
• OH-end group determination
• DSC analysis for Tg, Tc, Tm
• Heavy metals
• VOC analysis
• Adhesives in PET
