## Abstract

Systems, devices, and methods are described for providing a bag having an internally reinforced header. A reinforcing material is combined with a bag material to provide strength to the reinforced header. The reinforcing material and the bag material are aligned during manufacturing such that the reinforcing material is positioned in a header area of a bag formed by folding the bag material. A seal that passes through both the reinforcing material and the bag material retains the reinforcing material within the bag header. A bag handle may then be punched into the header through the bag material and the reinforcing material.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 2)

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.

### Claim 4 (depends on 2)

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.

### Claim 5 (depends on 1)

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

### Claim 6 (depends on 5)

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

### Claim 7 (depends on 6)

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

### Claim 8 (depends on 7)

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

### Claim 9 (depends on 5)

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

### Claim 10 (depends on 9)

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

### Claim 11 (depends on 9)

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

### Claim 12 (depends on 11)

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

### Claim 13 (depends on 1)

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

### Claim 14 (depends on 13)

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

### Claim 15 (depends on 14)

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

### Claim 16 (depends on 1)

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.

### Claim 17 (depends on 1)

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

### Claim 18 (depends on 1)

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

### Claim 19 (depends on 1)

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

### Claim 20 (depends on 19)

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

### Claim 21 (depends on 20)

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.

### Claim 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.
