Storage bag

A storage bag comprising:

• a body extending longitudinally from a first end of the bag to a second end of the bag, the body defining an inner surface and an outer surface,
• wherein the inner surface comprises a higher melting polymer and the outer surface comprises a lower melting polymer,
• wherein a portion of the inner surface overlaps a portion of the outer surface to form a first lap seam;
• wherein, the first lap seam extends longitudinally from the first end to the second end, the first lap seam being positioned between opposing lateral edges of the bag to divide the bag into first and second sides
• a joint at the first end;
• and
• first and second composite sheets,
• wherein each of the first and second composite sheets have a first side formed of a higher melting polymer and a second side formed of a lower melting polymer,
• wherein the first composite sheet is folded over the joint, at the first side of the bag, with the second side of the first composite sheet engaging the joint to form a second lap seam over the joint,
• wherein the second composite sheet is folded over the joint, at the second side of the bag, with the second side of the second composite sheet engaging the joint to form a third lap seam over the joint.
