Abstract
A reducible volume container includes a package wall having an interior surface and an exterior surface, with at least one tear strip formed in the package wall. The tear strip is defined by a pair of generally parallel frangible tear lines. Each tear line includes a pair of generally parallel creases formed on the interior surface of the package wall, and a linear cut formed in the exterior of the package wall. The linear cut is disposed in an area between the parallel creases and has a depth extending only partly through the thickness of the package wall.
