Worldwide scientific research over the last 20 yr using simplified models (polymer container, food or simulated food in liquid form) has shown that interaction of foods in contact with packaging materials occurs via physico-chemical mechanisms which can be predicted. Community laws envisaging standardization of migration tests are based on this assumption. However, it must be born in mind that it is impossible to reproduce all possible circumstances envolving health risk to consumers, in view of the time and cost required and the range and number of substances to be controlled. Full details of model testing are given, emphasizing the importance of the diffusion coeff. in calculations.
