A package comprising: an outer film layer comprising an outer die cut, wherein the outer die cut defines a peripheral edge of a peelable flap portion of the package; and an inner film layer laminated to the outer film layer and comprising an inner die cut, wherein the inner die cut defines a location of an opening of the package and is formed inwardly of the outer die cut, wherein the inner die cut comprises: a first cross-directional cut line; first and second longitudinal cut lines (145, 150) extending continuously lengthwise from opposite ends of the first cross-directional cut line, respectively; and a second cross-directional cut line extending continuously between the first and second longitudinal cut lines (145, 150), opposite the first cross-directional cut line and extending outwardly from the first cross-directional cut line, and wherein the second cross-directional cut line has a non-zero first radius of curvature between its juncture with the first and second longitudinal cut lines (145, 150), characterized by a non-zero second radius of curvature at the juncture of each of the first and second longitudinal cut lines (145, 150) with the second cross-directional cut line, wherein the second radius of curvature is between approximately 0.3175 cm (0.125-inch) and approximately 1.905 cm (0.75-inch) and is smaller than the first radius of curvature, and wherein the first and second radii of curvature are selected so as to provide a second cross-directional cut line that, although not a straight line, minimizes the curvature of the second cross-directional cut line. an outer film layer comprising an outer die cut, wherein the outer die cut defines a peripheral edge of a peelable flap portion of the package; and an inner film layer laminated to the outer film layer and comprising an inner die cut, wherein the inner die cut defines a location of an opening of the package and is formed inwardly of the outer die cut, wherein the inner die cut comprises: a first cross-directional cut line; first and second longitudinal cut lines (145, 150) extending continuously lengthwise from opposite ends of the first cross-directional cut line, respectively; and a second cross-directional cut line extending continuously between the first and second longitudinal cut lines (145, 150), opposite the first cross-directional cut line and extending outwardly from the first cross-directional cut line, and a first cross-directional cut line; first and second longitudinal cut lines (145, 150) extending continuously lengthwise from opposite ends of the first cross-directional cut line, respectively; and a second cross-directional cut line extending continuously between the first and second longitudinal cut lines (145, 150), opposite the first cross-directional cut line and extending outwardly from the first cross-directional cut line, and wherein the second cross-directional cut line has a non-zero first radius of curvature between its juncture with the first and second longitudinal cut lines (145, 150), characterized by a non-zero second radius of curvature at the juncture of each of the first and second longitudinal cut lines (145, 150) with the second cross-directional cut line, wherein the second radius of curvature is between approximately 0.3175 cm (0.125-inch) and approximately 1.905 cm (0.75-inch) and is smaller than the first radius of curvature, and wherein the first and second radii of curvature are selected so as to provide a second cross-directional cut line that, although not a straight line, minimizes the curvature of the second cross-directional cut line.
