DIE CUT OPENING FOR MULTI-LAYER FLEXIBLE PACKAGE

摘要

A reclosable package is described that includes inner and outer film layers. Each of the inner and outer film layers includes die cuts that are designed to create a peelable flap portion that, when pulled back by the user, reveals an opening of the package for providing access to the contents of the package. In particular, the inner film layer has an inner die cut that includes a cross-directional cut line. While the cross-directional cut line in conventional packages is a straight line, the package described herein uses a line that has one or more radii of curvature. In this way, the vibrations that may otherwise be generated during the rotary die cutting process are reduced, and more consistent cut depths can be achieved.

主权项

1. 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, is formed inwardly of the outer die cut, and is formed on the peelable flap portion, wherein the inner die cut comprises:
a first cross-directional cut line;first and second longitudinal cut lines extending continuously lengthwise from opposite ends of the first cross-directional cut line, respectively; anda second cross-directional cut line extending continuously between the first and second longitudinal cut lines opposite the first cross-directional cut line, and wherein the second cross-directional cut line has a non-zero radius of curvature.
