Claim 10:
11. A multi-layer thermoplastic bag comprising:
an outer first thermoplastic bag comprising first and second opposing sidewalls joined together along a first side edge, an opposite second side edge, an open first top edge, and a closed first bottom edge;
an inner second thermoplastic bag positioned within the first thermoplastic bag, the second thermoplastic bag comprising third and fourth opposing sidewalls joined together along a third side edge, an opposite fourth side edge, an open second top edge, and a closed second bottom edge,
wherein a hem seal secures a fold-over of the outer first thermoplastic bag and the inner second thermoplastic bag forming a hem channel;
wherein the outer first thermoplastic bag and the inner second thermoplastic bag each comprise a grab-zone extending from the first and third side edges to the opposite second and fourth side edges and from the hem seal a first distance toward the first and second closed bottom edges;
wherein at least a portion of the fold-over of the outer first thermoplastic bag and the inner second thermoplastic bag extends from the hem seal across the grab-zone over an inside surface of the inner second thermoplastic bag thereby forming an extended hem skirt; and
a hem skirt seal positioned below the hem seal that secures the extended hem skirt to the inside surface of the second thermoplastic bag;
wherein the portion of the fold-over of the outer first thermoplastic bag and the inner second thermoplastic bag forming the extended hem skirt comprises only one of the outer first thermoplastic bag or the inner second thermoplastic bag, which is secured to the inside surface of the inner second thermoplastic bag by both the hem seal and the hem skirt seal.
