A method of processing an oxygen scavenger film is disclosed, which comprises the steps of: (a) subjecting an oxygen scavenger film to actinic radiation at a dosage sufficient to trigger the oxygen scavenger film; then (b) rolling the triggered oxygen scavenger film onto a roll; and then (c) storing the rolled triggered oxygen scavenger film in a container, the container configured such that the oxygen scavenger exhibits no substantial oxygen scavenging activity while inside the container. A method of distributing an oxygen scavenger film is also disclosed, which comprises the steps of: (a) providing a tubular film at a first location, the film comprising: (i) an oxygen barrier layer; and (ii) an oxygen scavenger layer; (b) subjecting the tubular film to actinic radiation at a dosage sufficient to trigger the oxygen scavenger layer; (c) collapsing the tubular film, thereby substantially eliminating air from the interior of the tubular film, such that the resulting oxygen scavenger layers are closer to a collapsed interface of the tubular film than the resulting oxygen barrier layers; (d) rolling up the tubular film on a roll; and (e) transporting the roll of tubular film to a second location. These oxygen scavenger films are suitable for use in packaging oxygen sensitive products. |
