US Patent 12084601 Packaging patches having disinfecting sealing layer

A package includes a patch and a packaging film. The patch comprises a support and a sealing layer comprising chlorite ions. The support is permeable to chlorine dioxide. The packaging film has an inner surface defining at least a portion of an interior space of the package for housing an article. The packaging film is substantially impermeable to chlorine dioxide and is transparent to ultraviolet light. The patch is affixed to the inner surface of the packaging film by the sealing layer. Chlorine dioxide may be generated by subjecting the package to ultraviolet (UV) light such that the UV light reaches the sealing layer of the patch to convert the chlorite ions to chlorine dioxide.
