## Abstract

A package is provided that is formed from a packaging material, such as film, having increased adhesive in critical locations, such as adjacent folds in the end seal and other areas so that that the increased adhesive can at least partially fill voids adjacent such folds. The additional, localized sealant material is applied in a plurality of discrete locations in the end seal or other region adjacent where folds are formed and overlap with a sealant layer so as to provide additional sealant material for at least partially filling the voids without being present throughout the entirety, majority or large portions of the packaging material.

## Claims

### Claim 1

A package formed from a packaging material having at least a base layer and a sealant layer, the packaging material having a localized sealant material disposed on the sealant layer and in a plurality of discrete locations, the package having one or more end seal regions having folds with the discrete locations of the localized sealant material being adjacent to the folds such that the localized sealant material at least partially fills voids adjacent the folds;
wherein the package includes a first end seal region and a second end seal region, each of the first and second end seal regions having folds at lateral edges thereof, the discrete locations of the localized sealant material including a first pair of discrete locations adjacent the folds of the first end seal region and a second pair of discrete locations adjacent the folds of the second end seal region; and
wherein the package includes a fin seal extending between the first and second end seal regions and having a first portion disposed in the first end seal region with a first pair of fin seal folds and a second portion disposed in the second end seal region with a second pair of fin seal folds, the discrete locations of the localized sealant material including a third pair of discrete locations adjacent the first pair of fin seal folds and a fourth pair of discrete locations adjacent the second pair of fin seal folds.

### Claim 2 (depends on 1)

The package of claim 1, wherein the package is a flow wrap package with at least one food item disposed therein.

### Claim 3 (depends on 1)

The package of claim 1, wherein the sealant layer is a heat sealant layer, and the localized sealant material has a lower melt point as compared to a melt point of the heat sealant layer.

### Claim 4 (depends on 1)

The package of claim 1, wherein the base layer includes a plurality of different layers.

### Claim 5 (depends on 1)

The package of claim 1, wherein the packaging material is film.

### Claim 6 (depends on 3)

A method of making the package of claim 3, the method comprising:
unwinding the packaging material from a reel of packaging material, the packaging material having the heat sealant layer;
applying the localized sealant material in the plurality of discrete locations; forming the end seal regions having the folds of the end seal regions; and
applying heat to the end seal regions to cause portions of the heat sealant layer to adhere and to cause the localized sealant material to at least partially fill the voids adjacent the folds of the end seal regions.

### Claim 7 (depends on 6)

The method of making the package of claim 6, wherein the localized sealant material is applied after unwinding the packaging material from the reel of the packaging material.

### Claim 8 (depends on 3)

A method of making the package of claim 3 the method comprising:
unwinding the packaging material from a reel of packaging material, the packaging material having the heat sealant layer;
applying the localized sealant material in the plurality of discrete locations;
forming the fin seal;
applying heat to the fin seal to cause portions of the heat sealant layer to adhere and to cause the localized sealant material to at least partially fill voids adjacent the folds of the fin seal;
forming the end seal regions having the folds of the end seal regions; and
applying heat to the end seal regions to cause portions of the heat sealant layer to adhere and to cause the localized sealant material to at least partially fill the voids adjacent the folds of the end seal regions.
