Abstract
Approaches for desiccant device within an enclosure protecting sensitive electronic equipment. Electronic equipment, such as a hard-disk drive (HDD), may comprise a desiccant device that possesses a water vapor permeability rate that matches or is substantially similar to the water vapor permeability rate of the enclosure. In this way, desiccant devices may prevent the desiccant material enclosed within from releasing large amounts of humidity into the interior of the electronic equipment. The desiccant device may be constructed using a laminate material that comprises an interior facing material and an exterior facing material. The exterior facing material permits water to diffuse faster therethrough than the interior facing material.
