Oligomers in PBT and PEN polyesters

Scientists characterize oligomers in polybutylene terephthalate and polyethylene naphthalate intended for food contact; oligomer migration from PBT considered safe based on threshold of toxicological concern considerations

Proceedings of ILSI NA workshop on FCMs

Summary of workshop on ‘Scientific advances and challenges in safety evaluation of food packaging materials’ now published

EFSA: 6th FIP network meeting on FCMs

EFSA’s Food Ingredients and Packaging Scientific Network held 6th meeting on food contact materials on July 10-11, 2018, discussed ongoing activities, printing inks, paper and board FCMs

Chemicals associated with plastic packaging

Study compiles database of chemicals associated with plastic packaging (CPPdb); at least 148 substances highly hazardous, many untested or unknown

Prioritization of NIAS for risk assessment

Scientists propose strategy to prioritize non-intentionally added substances detected by non-targeted screening in paperboard FCMs for risk assessment based on exposure estimates and in silico predictions of toxicity

NIAS in polypropylene films

Scientists study migration from food packaging films made of polypropylene; 74 compounds identified, 76% of them NIAS; 35% of samples show migration exceeding either SML or Cramer class-based recommendations

Updated dossier on NIAS

FPF publishes 2nd edition of NIAS dossier and updated summary article, including new examples of non-intentionally added substances and risk assessment concepts; German translation of dossier available

Non-intentionally added substances (NIAS)

NIAS are chemicals present in food contact materials and articles which have not been added for a technical reason. They include side products, breakdown products, and contaminants. Although more and more NIAS have been identified over time, by far not all are known. Risk assessment and management of NIAS therefore present particular challenges. The updated dossiers in English and German replace the previous edition with the DOI: 10.5281/zenodo.33514.  

Non-intentionally added substances (NIAS)

NIAS occur in all types of food contact materials, are often unknown, may migrate into food; summary article and dossier provide definitions, examples, legal background, risk assessment strategies

BfR statement on polyamide oligomers

German risk assessment institute evaluates migration of polyamide oligomers from kitchen utensils into food; exposure likely to exceed threshold of toxicological concern; call for more toxicity studies
