Can air go in or out of my container if I use Circumvent or AirFoil?
Yes! Circumvent and AirFoil utilize a bi-directional venting material that allows air to pass in either direction depending upon the conditions. Whether pressure builds-up within the container or a vacuum is formed, Circumvent or AirFoil will prevent the package from swelling or collapsing. Circumvent and AirFoil act as a sterile barrier.
