Abstract
An apparatus, system, and method are disclosed for controlling out-gassing and humidity in a closed space-constrained environment. In particular, an environment control device is disclosed which is made using thermoforming techniques such that the walls of the device are much thinner than other conventional devices. This allows for the device to be used in space-constrained environment while still providing a sufficient amount of absorber material such as a desiccant. The apparatus includes a base made up of a thin flexible plastic film thermoformed to create a cavity having at least one wall, the cavity having an opening on one side. An absorber material, such as a desiccant, is placed inside the cavity, and a cover made up of a permeable layer sealed to the base opening to complete an enclosure for holding the absorber material.
