Research relating to ionizing treatment has been carried out on ‘food simulants polyethylene film’ combinations. Pouches have been irradiated by gamma photons or accelerated electrons at a 10kGy dose. Overall, the migration test has given some interesting results, particularly in the case of acid simulant, where a limit of validity has been found for the overall migration method. Many radiolytic products and degradation reactions have been indicated, and it has been established that the high permeability of packaging film to oxygen had influenced the radiolytic product yields. The results show some interactions between packaging film and food simulant under irradiation conditions.
