Abstract
A gas permeable package for a preservative agent is fabricated from a material which includes a support having pores therein sufficiently large to permit passage of gas therethrough but small enough to retain a preservative agent. There is a conformal, hydrophobic and oleophobic coating on the porous support member. The coating includes a fluoroacrylate based polymer.
