ABSTRACT:
A method for maintaining hydration of the contents of water-impermeable packages containing items to be sterilized includes placing a moisture-releasing humidifying device into the package with the items to be sterilized, hermetically sealing the package, and releasing moisture from the moisture-releasing humidifying device into the package before the package is exposed to the gaseous sterilant. The moisture-releasing humidifying device includes an absorbent material and a cover about the absorbent material. The cover is made at least partially of a hydrophobic and vapor-permeable material such that moisture absorbed by the absorbent material passes through the vapor-permeable material to effect humidification within the package.
