Die cut opening for multi-layer flexible package

A package comprising:

• a laminate comprising an outer film layer and an inner film layer, wherein the outer film layer and the inner film layer are coextensive;
• the outer film layer comprising an outer die cut, wherein the outer die cut extends within the outer film layer, wherein the outer die cut defines a peripheral edge of a peelable flap portion of the package, and wherein the outer die cut comprises:
• an outer layer first cross-directional cut line;
• and
• outer layer first and second longitudinal cut lines extending continuously lengthwise from opposite ends of the outer layer first cross-directional cut line, respectively;
• the inner film layer-comprising an inner die cut, wherein the inner die cut extends within the inner film layer, 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 has only one axis of symmetry and comprises:
• an inner film first cross-directional cut line;
• inner film first and second longitudinal cut lines extending continuously lengthwise from opposite ends of the inner film first cross-directional cut line, respectively;
• and
• an inner film second cross-directional cut line, opposite the first cross-directional cut line, connecting the inner film first and second longitudinal cut lines and extending away from the inner film first cross-directional cut line, wherein the inner film second cross-directional cut line has multiple non-zero radii of curvature between its juncture with the inner film first and second longitudinal cut lines, and
• wherein the inner film second cross-directional cut line has a first non-zero radius of curvature at the juncture of the inner film first longitudinal cut line with the second cross-directional cut line a second non-zero radius of curvature at the juncture of the second longitudinal cut line with the second cross-directional cut line, and a third non-zero radius of curvature along the inner film second cross-directional cut line between the first juncture and the second juncture, wherein the first, second and third non-zero radii of curvature are part of the multiple non-zero radii of curvature,
• wherein the inner film first and second longitudinal cut lines are generally parallel to a longitudinal axis, and the outer layer first and second longitudinal cut lines are generally parallel to the longitudinal axis, when the peelable flap portion of the package is in a closed configuration,
• wherein inner die cut has a depth less than a thickness of the inner film, with a consistent tolerance of about +/−6 microns, and
• wherein the outer film first cross-directional cut line comprises a plurality of package integrity features which extend away from the inner film first cross-directional cut line.
