Abstract
An oxygen scavenger film strip is included in various package configurations. The film strip is discrete and therefore can be used as a strip of any suitable length or width, to cover all or part of an oxygen-sensitive article in the package. The film strip can be used in conjunction with any suitable covering films, forming or non-forming webs, substrates, or trays; and in any suitable packaging systems such as HFFS, VFFS, VSP, modified atmosphere, thermoform/lidding, and the like. Because the film strip is made separately from the packaging films used in the particular package, the primary packaging does not have to be compromised by modifications needed to accommodate an oxygen scavenging functionality in the packaging material. The use of a discrete film strip also offers great latitude and efficiency in the dimensions of the film strip with respect to the overall package dimensions, and the placement of the film strip with respect to the packaged article.
