Recyclable woven plastic bags with quad-seal and/or k-seal

A method of manufacturing a bag, the method comprising:

• providing a web of material comprising a first layer, a second layer, and a third layer, the first layer comprising woven strips of a first material comprising polyethylene, polypropylene, or a combination thereof, the second layer being laminated to the first layer, the second layer comprising a second material comprising a film comprising polyethylene, polypropylene, or a combination thereof, and the third layer comprising a third material comprising a laminate resin comprising polyethylene, polypropylene, or a combination thereof;
• separating a first end and a second end of the web of material, wherein the web of material between the first end and the second end forms a sheet for a bag comprising a front wall, a back wall, a first side wall, and a second side wall, each wall having a predetermined size and a top end and a bottom end;
• forming a plurality of bag corners between each of the front wall and the first side wall, the back wall and the first side wall, and the back wall and the second side wall;
• sealing together at least two of the front wall, the back wall, the first side wall, and the second side wall, thereby forming a folded tube;
• and
• sealing the front wall, the back wall, the first side wall, and the second side wall with a plurality of seals arranged at the bottom end and extending between 30°and 45°from an edge of each of the front wall, the back wall, the first side wall, and the second side wall to form a plurality of diagonal seals at the bottom end.

A method of manufacturing a bag, the method comprising:

• providing a web of material comprising at least a first layer and a second layer, the first layer comprising woven strips of a first material comprising polyethylene, polypropylene, or a combination thereof, and the second layer comprising a second material comprising a co-extruded film layer comprising a first film layer and a second film layer, wherein the first film layer and the second film layer each comprise polyethylene, polypropylene, or a combination thereof, wherein the co-extruded film layer is laminated to the first layer, and wherein the web of material is recyclable;
• separating a first end and a second end of the web of material, wherein the web of material between the first end and the second end forms a sheet for a bag comprising a front wall, a back wall, a first side wall, and a second side wall;
• forming at least one corner of the bag between edges of the front wall and the first side wall, the front wall and the second side wall, the back wall and the first side wall, and the back wall and the second side wall;
• sealing a corner of at least one of the front wall and the first side wall, the back wall and the first side wall, the back wall and the second side wall, and the front wall and the second side wall, thereby forming a folded tube;
• and
• forming a flat bottom bag by sealing a bottom end of the front wall, back wall, first side wall, and second side wall.
