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/cm. 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.

An apparatus for selectively dispensing a web from a plurality of rolls of serrated bags or layflat tubing comprises a web selector for selecting and advancing a web from the plurality of rolls; a bag driver for advancing the selected web and separating a bag from the web; and a bag transfer device for transporting the separated bag from the bag driver to a location for processing. A sealer/cutter is used to produce a bag from the layflat tubing. A method of selectively dispensing a web from a plurality of rolls of serrated bags or layflat tubing comprises selecting and advancing a web from the plurality of rolls of serrated bags; advancing the selected web and separating a bag from the web; and transporting the separated bag to a location for further processing. In the case of layflat tubing, the selected web is sealed and cut to make a bag.

The invention provides a packaging container including a box adjustable between an open configuration and a closed configuration, the box including a plurality of side panels and a bottom arranged to define a storage compartment and an opening, the storage compartment being accessible through the opening when the box is in the open configuration. A first flap and a second flap form a first pair of opposing flaps, each of the first and second flaps being attached to a corresponding side panel and adapted for folding across at least a portion of the opening when the box is in the closed configuration. The box includes a second pair of opposing flaps, each flap of the second pair of opposing flaps being attached to a corresponding side panel and adapted for folding across at least a portion of the opening when the box is in the closed configuration. A sheet is provided, having a first end affixed to the first flap and a second end affixed to the second flap, wherein when the box is in the closed configuration, a first portion of the sheet is within the storage compartment, a second portion of the sheet is between the first flap and at least one flap of the second pair of opposing flaps, and a third portion of the sheet is between the second flap and at least one flap of the second pair of opposing flaps.
