  • Sterilization Validation System and Method
    Publication number: 20220296759
    Abstract: A sterilization validation system and method are disclosed that ensure sterilization of packaging materials that contain certain sterilized items that have been sterilized in a cleanroom environment. In accordance with the disclosed subject matter, garments (or other items or materials) that are sterilized inside autoclave or breather bags may be secured within tote liners that ensure sterility of the exterior of the breather bags containing the garments. Not only is it possible to ensure a recipient that the garment is sterile, but it is also possible to verify that the outside of the breather bag itself is also sterile, since the breather bag will remain sterilized inside the tote liner during shipping.
