Abstract: A pouch for holding a medical device. A base layer has a base periphery, a base back end and opposing base outer edges. A breathable first web is on the base layer and adapted to permit a sterilization gas to pass therethrough. A non-breathable middle film is adhered to the first web. A breathable second web is attached to the middle film, and a non-breathable top layer is over the base layer, thereby the pouch includes five layers. A primary seal adheres the base layer and the top layer. Then a secondary seal adheres the middle film and the second web to the base layer. The secondary seal is coextensive with the primary seal but then extends a partial width of the primary seal to thereby form a setback, wherein the setback allows the first web, the middle film and the second web to be formed in a single sealing step.
