Abstract
A packaging system or storage arrangement that includes provision to indicate the presence of oxygen. An oxygen-sensitive material is placed inside a sealable container. Air is evacuated from the sealable container and the sealable container is sealed to isolate the oxygen-sensitive material from oxygen. The sealable container is then irradiated with an effective amount of radiation to activate the oxygen-sensitive material such that the oxygen-sensitive material will undergo a visual change in the presence of oxygen after the oxygen-sensitive material has been irradiated. The visual change provides an indication of the presence of oxygen inside the sealable container.
