Abstract

Flexible film packages having an easily opened package feature incorporated therein and method of producing such packages are provided. The package opening feature may be incorporated into a variety of package formats such as flow wrapped packages having a longitudinal seal (including fin seals or lap seals) or packages with side seals (including two-, three-, or four-side seal pouches). In one illustrative approach, the package opening feature is disposed adjacent or at a package seal, such as, for example, an end seal, a top seal, a bottom seal, a side seal, or a longitudinal seal. The flexible film laminate has at least first and second film layers, and at least one of the film layers defining an interior cavity configured to hold food products. In a number of configurations, the flexible film packages may be reclosable or resealable.

First claim

What is claimed:

1. A package comprising:
a flexible film laminate having at least first and second film layers, the flexible film laminate defining at least part of an interior cavity and at least the second film layer of the flexible film laminate having:
a first pair of edge portions forming a first end seal,
a second pair of edge portions forming a second end seal, and
a third pair of edge portions forming a longitudinal seal extending from the first end seal to the second end seal;

the flexible film laminate having a first side, a second side, and a laminate thickness therebetween, the second side of the flexible film laminate oriented toward the interior cavity of the package;
gripping portions formed in the flexible film laminate adjacent the first end seal, the gripping portions having a pull tab having a first position when the package is closed and a second position when the pull tab, a portion of a sealing panel of the first film layer, and a flap of the second film layer are disposed upward from a remainder of the package to expose a package opening; and
an outer partial-depth cut extending from the first side of the flexible film laminate through at least a portion of the first film layer, the outer partial-depth cut forming a narrowing portion in the first film layer to facilitate lifting of the sealing panel of the first film layer from a remainder of the package,
wherein the flap of the second film layer and a trailing edge of the pull tab are defined by inner partial-depth cuts in the second side of the flexible film laminate through at least a portion of the second film layer, and a gripping edge of the pull tab is defined by a throughcut through the entire thickness of the flexible film laminate, the throughcut intersecting the outer partial-depth cut, and wherein the gripping edge is offset from a leading edge of the package.

2. The package of claim 1 wherein the gripping portions further comprises an opposing gripping tab defined by the leading edge of the package.

3. The package of claim 2 further comprising an extension portion defined by the leading edge of the package and a corresponding cut-out portion defined by a trailing edge of the package.

4. The package of claim 3 wherein the opposing gripping portion is disposed upon the extension portion of the package and the pull tab is partly disposed upon the extension portion of the package.

5. The package of claim 4 wherein the throughcut is a line cut disposed on the extension portion and extends from a first extension edge to a second extension edge.

6. The package of claim 1 wherein the first film layer extends at least one of:
partially over the second film layer and is disposed in at least a portion of the first end seal;
within the third edge portions of the second film layer and extends from the first end seal to the second end seal; and
over the second film layer such that the first and second film layers are coextensive with one another.

7. The package of claim 1 further comprising a resealable adhesive disposed between at least portions of the first and second film layers and the sealing layer of the first film layer is resealable with respect to the second film layer with the resealable adhesive disposed between the first and second film layer.

8. The package of claim 1 wherein the pull tab further comprises a cut-away portion of the second film layer defined by the throughcut and a portion of the outer partial-depth cut disposed at the first end seal.
