Abstract

A package containing rolled products. The package has an upper side, a lower side opposite and generally parallel to the upper side and four side walls. The sidewalls connect the upper side to the lower side. The package has at least first and second polymer films, the first polymer film forming the upper side and at least a portion of the four side walls, the second polymer film forming at least a portion of the lower side.

First claim

What is claimed is:

1. A package containing rolled products, the package comprising an upper side, a lower side opposite and generally parallel to the upper side; four side walls including two end walls, the sidewalls connecting the upper side to the lower side; the package comprising at least a first and a second polymer film, the first polymer film having first physical properties and forming the upper side and at least a portion of the four side walls, the second polymer film having second physical properties and forming at least a portion of the lower side, wherein the first and second polymer films are joined by at least one corner fin seal along one edge defined by the juncture of one side wall and the lower side, and wherein each of the two end walls include a gusset seal, wherein the gusset seal comprises a first gusset flap connected to an edge of the upper side and the first gusset flap folded approximately perpendicular from a plane formed by the upper side, and a second gusset flap connected to an edge of the lower side and the second gusset flap folded approximately perpendicular from a plane formed by the lower side, wherein the first and second gusset flaps overlap only at end edges of the first and second gusset flaps to form the gusset seal, and wherein the plane of the upper side and the plane of the lower side are spaced from each other and are parallel with each other.

2. The package containing rolled products claim 1 , wherein the rolled products are rolled sanitary tissue products.

3. The package containing rolled products claim 1 , wherein the second polymer film has a better abrasion resistance than the first polymer film.

4. The package containing products of claim 1 , wherein the package has two said fin seals.

5. The package containing products of claim 1 , wherein the first polymer film has a lower caliper than the second polymer film.

6. The package containing products of claim 1 , wherein the upper side, lower side and side walls form major faces of the package, and the package has at least four seal-free faces.

7. A package containing rolled sanitary tissue products, the package comprising an upper side, a lower side opposite and generally parallel to the upper side; four side walls including two end walls, the sidewalls connecting the upper side to the lower side; the package comprising at least a first and second polymer films, the first polymer film having first physical properties and forming the upper side and at least a portion of the four side walls, the second polymer film having second physical properties and forming the lower side, wherein the first and second polymer films are joined by two fin seals, one each along each corner edge defined by two opposing side walls and the lower side, and wherein each of the two end walls include a gusset seal, and wherein the upper side, lower side and side walls form major faces of the package, and the package has at least four seal-free faces and two faces with gusset seals, wherein the gusset seals each comprise a first gusset flap connected to the upper side and a second gusset flap connected to the lower side, wherein the first and second gusset flaps overlap only at end edges of the first and second gusset flaps.

8. The package of claim 7 , wherein the sanitary tissue products are selected from the group of paper towels and toilet tissue.

9. A package containing rolled products, the package comprising an upper side, a lower side opposite and generally parallel to the upper side; four side walls including two end walls, the sidewalls connecting the upper side to the lower side; the package comprising at least a first and a second polymer film, the first polymer film forming the upper side and at least a portion of the four side walls, the second polymer film forming at least a portion of the lower side, wherein the first and second polymer films are joined by two fin seals, one each along each corner edge, and wherein each of the two end walls include a gusset seal, wherein the gusset seal comprises a first gusset flap connected to the upper side and a second gusset flap connected to the lower side, wherein the first and second gusset flaps overlap only at end edges of the first and second gusset flaps.

10. The package of claim 9 , wherein the rolled products are rolled sanitary tissue products.
