Abstract

A process for sterilizing an article, more particularly packaging material, by wetting the article with a sterilizing solution having an active-chlorine-concentration in the range of 500 to 20,000 mg/l, and treating the sterilized article with an aqueous solution of hydrogen peroxide to deactivate any remaining active-chlorine.
