Abstract
A packaged product comprising a plurality of individual containers, a corrugated board or paperboard carrier wall disposed along a portion of the periphery and shrink wrapping. The shrink wrap film has vent holes that are specifically sized and spaced apart as needed to provide adequate venting of one or more volatiles out of the shrinkwrapped multi-pack to prevent package staining and/or discoloration of the package's printing inks. The container wall preferably has an open top and bottom and also has two free edges spaced from each other so as to leave a portion of the periphery uncovered by the wall.
