The condition of time and temperature under which PET (polyethylene terephthalate) is used in food contact applications is reviewed. The effect upon overall migration into fat simulants of varying temperature, time, thickness and crystallinity of the PET is discussed, with experimental data. Specific migration of monomers, catalyst residues, colourants and acetaldehyde from PET into food simulants is reported.
