The paper surface of the pouch should be facing up to allow moisture to escape (see picture 2). Picture 2: Single pouch placed the correct way on tray in the autoclave. Bonus: Ideally, pouches should be placed vertically, in an autoclave-safe rack (see picture 3). Picture 3: Pouches placed the correct way in rack in the autoclave.
