Abstract
A bag can be formed of a material having a layer that is substantially water-impervious. A portion of the material can be folded to form a base of the bag. Water-based adhesives can be used with the folded portions to form the base, and openings can be provided in the layer of the material to permit the adhesives to dry.
Claims65
A bag comprising:
- a body material comprising a first paper ply and a substantially water-impervious polyolefin layer outside of the first paper ply, wherein the body material defines a front wall, a rear wall, a first side wall extending between the front and rear walls, and a second side wall extending between the front and rear walls;
- a front extension panel depending from the front wall, a rear extension panel depending from the rear wall, a first side extension panel depending from the first side wall, and a second side extension panel depending from the second side wall, wherein the extension panels are formed of the body material and are folded inward to define a base of the bag, wherein the polyolefin layer includes one or more permeable regions in each of the rear extension panel, the first side extension panel, and the second side extension panel, wherein each of said one or more permeable regions comprise one or more openings, and wherein said one or more permeable regions are constrained to the extension panels;
- and
- an adhesive attaching the rear extension panel to each of the first and second side extension panels, wherein a portion of the adhesive is between a permeable region of the rear extension panel and a permeable region of the first side extension panel, and wherein a portion of the adhesive is between a permeable region of the rear extension panel and a permeable region of the second side extension panel.

A bag comprising:
- a body material comprising a first paper ply and a substantially water-impervious layer outside of the first paper ply, wherein the body material defines a front wall, a rear wall, a first side wall extending between the front and rear walls, and a second side wall extending between the front and rear walls;
- a first extension panel depending from at least one of the walls and comprising a portion of the body material, the first extension panel comprising a first permeable region that comprises one or more openings through the substantially water-impervious layer, and a second extension panel depending from another of the walls and comprising a portion of the body material, the second extension panel comprising a second permeable region that comprises one or more openings through the substantially water-impervious layer, wherein the first and second extension panels are folded relative to the walls from which they depend such that at least a portion of the substantially water-impervious layer of the first extension panel faces at least a portion of the substantially water-impervious layer of the second extension panel;
- and
- an adhesive attaching the first paper ply of the first extension panel to the first paper ply of the second extension panel, wherein the adhesive extends from the first paper ply of the first extension panel through the one or more openings in the first permeable region and further extends through the one or more openings in the second permeable region to the first paper ply of the second extension panel.

A bag comprising:
- a body material comprising a first paper ply and a substantially water-impervious polyolefin layer outside of the first paper ply, wherein the body material defines a front wall, a rear wall, a first side wall extending between the front and rear walls, and a second side wall extending between the front and rear walls;
- a first extension panel depending from at least one of the walls and comprising a portion of the body material and a second extension panel depending from another of the walls and comprising a portion of the body material, wherein each of the first and second extension panels comprises a permeable region that includes one or more openings through the substantially water-impervious layer, and wherein the first and second extension panels are folded relative to the walls from which they depend;
- and
- an adhesive positioned between the first and second extension panels, wherein the adhesive is in contact with the permeable region of the first extension panel and is in contact with the permeable region of the second extension panel, and wherein the permeable region of the first extension panel is positioned over the permeable region of the second extension panel.
