摘要:
The invention is a method, triggering unit, and system for activating an oxygen scavenging composition at high speeds. The triggering unit includes a plurality of UV lamps that can operate at increased temperatures and have high output intensites from about 10 to 35 mW/cm2. The triggering unit can activate films at speeds from about 20 to 100 fps. Mercury amalgam lamps are useful in the practice of the invention. The invention also includes a UV dose management system and film tensioning system that facilitates triggering at high film speeds. The UV dose management system controls the amount of UV exposure that the film receives so that the oxygen scavenging rate of the activated composition can be controlled.
