Internally reinforced header bag

1. A method of manufacturing reinforced bags, comprising:

providing a bag material;

providing a reinforcing material;

aligning the reinforcing material with an area of the bag material that forms a header of the bag;

folding the bag material at a center line of the bag material, wherein the folding positions the reinforcing material in an internal region of the bag material; and

applying a seal that passes through the bag material and the reinforcing material;

wherein the seal is applied through two layers of the bag material and the reinforcing material.

2. The method of claim 1 , further comprising attaching the reinforcing material to the bag material before applying the seal.

3. The method of claim 2 , wherein attaching the reinforcing material to the bag material comprises attaching the materials with one of a mechanical fastener, an adhesive, stitching, a hot tack seal, a cold pressure seal, or a static pin.

4. The method of claim 2 , wherein:

attaching the reinforcing material to the bag material comprises temporarily attaching the materials; and

applying a seal comprises permanently attaching the materials.

5. The method of claim 1 , wherein the reinforcing material is aligned with the center line of the bag material.

6. The method of claim 5 , wherein an edge of the reinforcing material is disposed adjacent to the center line.

7. The method of claim 6 , wherein the seal is applied through two layers of the bag material and one layer of the reinforcing material.

8. The method of claim 7 , wherein a lower portion of the reinforcing material extends below the seal.

9. The method of claim 5 , wherein the reinforcing material is centered on the center line of the bag material.

10. The method of claim 9 , wherein folding the bag material further comprises folding the reinforcing material at a center line of the reinforcing material.

11. The method of claim 9 , wherein the seal is applied through two layers of the bag material and two layers of the reinforcing material.

12. The method of claim 11 , wherein two lower portions of the reinforcing material extend below the seal.

13. The method of claim 1 , wherein the reinforcing material is aligned with a first edge of the bag material.

14. The method of claim 13 , further comprising sealing the first edge of the bag material to a second edge of the bag material.

15. The method of claim 14 , wherein the sealed edges form a top of the bag.

16. The method of claim 1 , further comprising applying a graphic to an exterior surface of the bag material after aligning the bag material and the reinforcing material.

17. The method of claim 1 , wherein the bag material comprises an exterior graphic that is applied before providing the bag material.

18. The method of claim 1 , wherein the seal prevents the reinforcing material from shifting relative to the bag material.

19. The method of claim 1 , further comprising punching a handle into the header of the bag.

20. The method of claim 19 , wherein the handle is punched through both the bag material and the reinforcing material.

21. The method of claim 20 wherein the folding forms a top edge of the reinforced bags and edges of the plastic film parallel to the top edge form an open bottom edge of the reinforced bags.

22. A method of manufacturing reinforced bags from a plastic film, comprising:

aligning a reinforcing material with an area of the plastic film that forms a header of the bag;

folding the plastic film along an edge to form a first panel and a second panel, with the reinforcing material between the first panel and the second panel; and

applying a seal that passes through the first panel, the second panel, and the reinforcing material between the first panel and second panel.
