Aluminum foil in flexible packaging material provides essentially complete barrier to oxygen (and moisture). Virtually all plastics used for flexible packaging materials do allow passage of these gases in response to partial pressure differences between the package’s interior (e.g., 0% oxygen) and the surrounding environment (21% oxygen).
