ABSTRACT:
A pipe bag is constructed from a flexible composite material which is airtight but readily permits the transmission of moisture vapor. At least one layer of the flexible composite material is a continuous hydrophilic layer. When a moisture vapor concentration gradient is present across said hydrophilic layer it transfers substantial amounts of water throug the layer by absorbing water on the side of the layer at which the higher water vapor concentration exists, and desorbing water on the opposite side of the layer at which the water vapor concentration is lower. As a result of this the moisture concentration within the bag is regulated.
