  • Desiccant bag with enclosed EAS tag and security markings
    Patent number: 6977589
    Abstract: A desiccant bag for adsorbing moisture from a surrounding space in a packaged product includes on its inner surface an electronic article surveillance or EAS tag which enables detection of stolen products by theft or shoplifter detectors. The EAS tag is not visible from the outside of the bag or product package, and is thus unlikely to be detected and removed by a thief. The bag may also be printed with an invisible message or taggant containing information such as source or intended destination.

  • Desiccant system
    Publication number: 20030121418
    Abstract: A desiccant system in which a body of water-vapor-adsorbing desiccant material is sealed in a bag which is permeable to water vapor, but not to liquid water or particulates. A humidity indicator is sealed to the bag, and is sensitive to humidity within the bag, but not to water or water vapor outside the bag. The indicator changes color when a predetermined humidity level has been reached within the bag, and thereby to signal that the bag should be replaced.
