A method of producing flexible polypropylene fabric bags with heat fused seams comprising providing fabric pieces, wherein each fabric piece has a coated side and an uncoated side; positioning fabric pieces so that a coated side of one fabric piece faces a coated side of another fabric piece; selecting an area of fabric to be joined for forming a seam or joint; applying heat to the area to be joined that is less than the melting point of the fabrics, for forming one or more seams or joints and wherein the heat fused seams or joints of a resulting polypropylene bag retains at least 85% of the fabric strength without using sewing machines.

One embodiment of a universally attachable leash bag having an interior chamber for temporary storage of retrieved pet waste secured in waste bags and exterior pockets for supplies or personal belongings. Bag is formed of a single piece of material fitted with a zipper along the lower edges and partially up the side edges. When engaged, zipper creates a bag form with interior chamber. Zipper is utilized when emptying the chamber to prevent pet owner from direct handling of waste. The vertically extended sides of the bag, fitted with corresponding members of hook-and-loop tape, feed through the pet leash handle forming a secure method of attachment. The front edge of leash bag is fitted with a reinforcing device to create an opening for the extended end of the leash to pass through creating a secondary means of attachment and a utility hook for carrying items or tertiary means of attachment.

A method for manufacturing a disposable biodegradable bag for carrying items then discarding the bag without creating unwanted pollution includes providing a first rectangular sheet of biodegradable material having a first top edge, a first bottom edge, and a first pair of lateral side edges. The first rectangular sheet of biodegradable material may be a first biodegradable dryer sheet. The method further includes providing a second rectangular sheet of biodegradable material having a second top edge, a second bottom edge, and a second pair of lateral side edges. The second rectangular sheet of biodegradable material may be a second biodegradable dryer sheet. The method further includes coupling the first bottom edge to the second bottom edge and coupling the first pair of lateral side edges to the second pair of lateral side edges to form a bag having an opening between the first top edge and the second top edge.
