PRODUCT PACKAGING HAVING SELF-STERILIZING COMPONENTS
20230022158 · 2023-01-26 ·

A package comprises: a sterile barrier packaging film; self-sterilizing components comprising: a plurality of chlorite ions and water, wherein the self-sterilizing components are substantially free of an energy-activated catalyst and of an acid-releasing compound; a package interior formed by hermetically sealing the sterile barrier packaging film; and a headspace within the package interior comprising carbon dioxide present in an amount of greater than or equal to 5% by volume of the headspace. When the package is exposed to ultraviolet (UV) light having a wavelength of 254 nm, the chlorite ions react with the water to generate chlorine dioxide (ClO.sub.2), which is released into the headspace. In the absence of any UV light, there is not chlorine dioxide (ClO.sub.2) generation.
