ABSTRACT:
A packaging article comprises two sheets of material bonded to form a pouch, with one layer comprising a first sheet of a porous material, e.g., Tyvek® film, and a second nonporous sheet overlying and sealed to the first sheet. The second sheet is impermeable to passage of gas therethrough and includes a peelable film, e.g., of polyethylene, in contact with the first sheet of porous material to permit peeling removal of the second sheet from the first sheet. A method of integrity testing includes fabricating a packaging article, pressurizing same with a gas and monitoring pressure to determine package integrity, removing the peelable film, and exposing a packaging article to sterilant gas supplied through the porous first sheet.
