Abstract

A patch bag has at least two patches covering/protecting the same portion of the bag. The at least two patches can be “stacked one on top of the other”, with the surface of the first patch which is in contact with the bag being adhered to the bag, and at least a portion of the surface of the first patch oriented away from the bag being adhered to the second patch. The first patch could be larger than the second patch, or vice versa. The first patch could be thinner than the second patch, or vice versa.

Patch Bag Comprising Two Patches on One Surface

A patch bag has at least two patches covering/protecting the same portion of the bag. The at least two patches can be “stacked one on top of the other”, with the surface of the first patch which is in contact with the bag being adhered to the bag, and at least a portion of the surface of the first patch oriented away from the bag being adhered to the second patch. The first patch could be larger than the second patch, or vice versa. The first patch could be thinner than the second patch, or vice versa.

Having the first patch thinner than the second patch facilitates sealing the bag film to itself if the seal is through the first patch. Having a second patch over top of the first patch can improve adhesion between the first patch and the patch if the seal is made through the first patch. The presence of the second patch over top of the first patch provides a tougher patch bag over the area the second patch covers, without having to make a tougher patch film.

In an alternative patch bag, the first patch is adhered to the outside surface of the bag, with the second patch being adhered to the inside surface of the bag in an area which overlaps with, is contiguous with, or is within the area covered by the first patch. This could be done by laminating patches to both sides of a flat film, folding the film over and then sealing the film to result in an L-seal or side-seal patch bag. If two separate pieces of bag film are used, a...
