Abstract
A reducible volume container includes a package wall made from a laminated material having interior surface and an exterior surface, with at least one tear strip formed in the package wall. At least one layer of the laminated material is a monoaxially oriented material disposed on an inner surface of the package wall. The tear strip is defined by a pair of generally parallel frangible tear lines. Each tear line includes a linear cut formed in the exterior of the package wall. The linear cut is disposed generally parallel to the axial orientation of the axially-oriented material, and each linear cut has a depth extending only partly through the thickness of the package wall.
