Twelve plastics representing various chemical structures were studied as part of a program to determine the utility of plastics as packaging materials in the high radiation presentation of food. The plastics were exposed to selected dosages of Cobalt‐60 gamma radiation in vacuum and in air. Gas evolution and changes in infrared spectra as a result of irradiation were used to hypothesize the relative stability of these plastics to irradiation. Based on these facts it was found that plastics containing conjugated ring systems, ionic linkages, and chlorine in side groups were the most stable.
