Zusammenfassung:	An apparatus is provided for activating an oxygen scavenging composition that includes a plurality of UV lamps arranged in a bank and disposed in a UV chamber; the UV lamps include first and second sides through which UV light is transmittable. A series of guide rolls disposed in the UV chamber define a film pathway for directing a film in close proximity with the first and second sides of the UV lamps. The UV shade is arranged to wrap about the first and second sides of the UV lamps, and may be configured to move between an open, partially open, and closed position so that the dosage of UV light to which the film is exposed may be controlled by adjusting the degree to which the shade is open. As a result, the UV shade may limit UV exposure without having to turn off the UV lamps.
