Abstract

A wick resistant microwavable popcorn arrangement formed substantially entirely of non-fluorocarbon material includes a folded bag defining a bag interior. The folded bag includes first and second opposite face panels joined by first and second opposite side gussets defined by gusset folds. The bag is folded to define a portion of the interior with side creases defined at junctures between the first face panel and the first and second opposite side gussets. One or more non-activated sealant fields are arranged to overlap at least one of the side creases or the gusset folds, and are configured to provide a liquid-resistant barrier. The one or more non-activated sealant fields are configured to retain the unpopped popcorn kernels, an oil component, and/or a fat component positioned within the bag interior between the first and second side gussets.

First claim

What is claimed is:

1 . A wick resistant microwavable popcorn arrangement formed substantially entirely of non-fluorocarbon material, the wick resistant microwavable popcorn arrangement comprising:
a folded bag formed from folding a planar sheet to fold the planar sheet from a planar sheet form to a folded form, the folded bag defining a bag interior and including first and second opposite face panels joined by first and second opposite, inwardly directed, side gussets defined by gusset folds, the folded bag defining a portion of the bag interior with side creases defined at junctures between the first face panel and the first and second opposite side gussets; a first plurality of sealant fields comprising a first sealant material, respective sealant fields of the first plurality of sealant fields comprising the first sealant material overlapping each of the side creases and the gusset folds, wherein the respective sealant fields of the first plurality of sealant fields that overlap the gusset folds extend longitudinally and continuously between end seals on opposing ends of the folded bag; a second plurality of sealant fields comprising a second sealant material, respective sealant fields of the second plurality of sealant fields comprising the second sealant material overlapping a portion of the respective sealant fields of the first plurality of sealant fields comprising the first sealant material when the folded bag is in the planar sheet form and when the first sealant material is arranged at the side creases of the folded bag in the folded form, wherein the first sealant material is a different type than the second sealant material; a popcorn charge including unpopped popcorn kernels and at least one of an oil component or a fat component positioned within the bag interior between the first and second opposite, inwardly directed, side gussets, the first plurality of sealant fields comprising the first sealant material and the respective sealant fields of the second plurality of sealant fields configured to retain at least one of the unpopped popcorn kernels or at least one of the oil component or the fat component within the bag interior.

2 . The wick resistant microwavable popcorn arrangement as recited in claim 1 , wherein the first sealant material comprises a coating sealant configured to form a liquid barrier along each of the side creases and the gusset folds.

3 . The wick resistant microwavable popcorn arrangement as recited in claim 2 , wherein the coating sealant comprises at least one of a vinyl acetate polymer, a vinyl-acetate acrylic polymer, an acrylic polymer, a styrene-acrylic polymer, or a polyolefin polymer.

4 . The wick resistant microwavable popcorn arrangement as recited in claim 3 , wherein the second sealant material comprises an adhesive sealant.

5 . The wick resistant microwavable popcorn arrangement as recited in claim 4 , wherein the adhesive sealant comprises at least one of a polyvinyl acetate adhesive or an ethylene vinyl acetate-polyvinyl alcohol adhesive.

6 . The wick resistant microwavable popcorn arrangement as recited in claim 1 , wherein a thickness of the first plurality of sealant fields comprising the first sealant material is in the range of about 2 g/m2 to about 20 g/m2.

7 . The wick resistant microwavable popcorn arrangement as recited in claim 1 , wherein the respective sealant fields of the first plurality of sealant fields that overlap the side creases also extend longitudinally and continuously between end seals on opposing ends of the folded bag.

8 . A wick resistant microwavable popcorn arrangement formed substantially entirely of non-fluorocarbon material, the wick resistant microwavable popcorn arrangement comprising:
a folded bag formed from folding a planar sheet to fold the planar sheet from a planar sheet form to a folded form, the folded bag defining a bag interior and including first and second opposite face panels joined by first and second opposite, inwardly directed, side gussets defined by gusset folds, the folded bag defining a portion of the bag interior with side creases defined at junctures between the first face panel and the first and second opposite side gussets; a first plurality of sealant fields comprising a coating sealant material, respective sealant fields of the first plurality of sealant fields comprising the coating sealant material overlapping each of the side creases and the gusset folds, wherein the respective sealant fields of the first plurality of sealant fields that overlap the gusset folds extend longitudinally and continuously between end seals on opposing ends of the folded bag; a second plurality of sealant fields comprising an adhesive sealant material, respective sealant fields of the second plurality of sealant fields comprising the adhesive sealant material overlapping a portion of the respective sealant fields of the first plurality of sealant fields comprising the coating sealant material when the folded bag is in the planar sheet form and when the coating sealant material is arranged at the side creases of the folded bag in the folded form, wherein the coating sealant material is a different sealant type than the adhesive sealant material; a popcorn charge including unpopped popcorn kernels and at least one of an oil component or a fat component positioned within the bag interior between the first and second opposite, inwardly directed, side gussets, the first plurality of sealant fields comprising the coating sealant material and the respective sealant fields of the second plurality of sealant fields configured to retain at least one of the unpopped popcorn kernels or at least one of the oil component or the fat component within the bag interior.

9 . The wick resistant microwavable popcorn arrangement as recited in claim 8 , wherein the coating sealant material includes one or more of a vinyl acetate polymer, a styrene-acrylic polymer, a vinyl acetate-acrylic copolymer, an acrylic polymer, or a polyolefin polymer.

10 . The wick resistant microwavable popcorn arrangement as recited in claim 9 , wherein the adhesive sealant material includes one or more of a polyvinyl acetate adhesive or an ethylene vinyl acetate-polyvinyl alcohol adhesive.

11 . The wick resistant microwavable popcorn arrangement as recited in claim 8 , wherein the respective sealant fields of the first plurality of sealant fields that overlap the side creases also extend longitudinally and continuously between end seals on opposing ends of the folded bag.
