Gamma radiation ionizes the material and creates free radicals, which are the intermediate species in many chemical reactions. Applied radiation (cobalt source-60) with the monomers used to manufacture the plastic is induced formation of large polymer chains, and if the irradiation is continued material, special plastics are high degree of crosslinking catenary, which considerably improves their properties such as thermal and electrical insulation. Thus, some polymer degradation induced by radiation, is a useful property for some types of packaging.
