An interior-mountable pressure relief valve for packages containing food products such as coffee that normally tend to out-gas. The relief valve of the present invention can be made by thermoforming a pocket of a barrier type of semi-rigid film that has a heat seal membrane on one side. An indent can be made in the bottom of this pocket to receive a filter medium that covers an aperture in the bottom of the pocket. The filter medium can be heat-staked to the pocket. A pressure relief valve known in the art containing a base layer, a pair of rails and a flexible membrane can be placed in the pocket. This valve and pocket assembly can be can be treated with a mesh membrane that is heat sealable to the seal side to prevent disassembly or contamination. The product can then be wound on a level wound spool for shipping to an end user. The end user can take the carrier tape and dispense it into a single piece dose and then heat seal the carrier to the inside wall of the package.

A system and method for separating air into components uses an air dehydration membrane for removing water vapor from compressed air. Dried compressed air is then directed, from the dehydration membrane, into a gas separation module which may be a membrane system, different from the air dehydration membrane, or a pressure swing adsorption (PSA) system. The air dehydration membrane is made of a hydrophilic polymer having a permeability for water vapor which is greater than its permeability for air, and having low selectivity between oxygen and nitrogen. The air dehydration membrane has a hydrophilic coating, which itself may be a polymer. The coating does not affect the selectivity of the coated dehydration membrane with respect to oxygen and nitrogen, but does increase selectivity of the membrane with respect to water vapor.
