Non-intentionally added substances in PET bottles and closures
In this study the occurrence of non-intentionally added substances (NIAS) in polyethylene terephthalate (PET) bottles and closures was investigated. A row of compounds originating predominantly from additives and colour masterbatches could be identified. Besides, compounds from other sources such as from the beverages the PET bottles were filled with or from the PET polymer were also found. The results show that a screening for NIAS in masterbatches should be implemented in the production process of PET bottles.
