✦ Synopsis

Polyole®ns such as low density polyethylene are widely used as food packaging materials. Antioxidant additives are added to such polymers to prevent oxidative reactions during thermal processing. The migratory behaviour of Irganox 1076 and Irgafos 168 from LLDPE into several ethanolic simulating agents, in which the ethanol content ranged from 40±100%, and at different temperatures was investigated. Higher migration values were found at higher ethanol contents with a strong increase between 50 and 75% ethanol. An Arrhenius type relationship was found for these antioxidants with faster migration at higher temperatures.
