Abstract: During the manufacturing process the exterior surface of one or both of the sheets of plastic film which form the bags is treated with low temperature corona discharge plasma to raise the level of surface charge magnitude to at least 43 Dyne to increase the adhesion force between the bags. A recess is formed in each of the bags to further increase the adhesion. The increased adhesion causes the mouth of one bag to automatically open as the adjacent bag is removed from the rack. The recess is formed at the same time openings are created in the bags to accept the support rods of a dispensing rack. The bags can have simple edge sides or side gussets and may be provided in a package including a pouch which receives and supports the lower portions of the bags.

Abstract: A reusable, re-foldable bag with gussets includes a first bag wall; a first side panel; a second side panel; a second bag wall aligned and joined to the first bag wall by the first side panel and the second side panel at a first heat sealed side edge, a second heat sealed side edge, respectively; a bag bottom comprising a substantially planar, foldable surface, the first and the second bag walls, the first and the second side panels, and the bottom formed of a single sheet and together arranged to form a bag defining an opening at a top thereof; a first gusset and a second gusset heat sealed onto the first side panel at the interior of the bag; and a third gusset and a fourth gusset heat sealed onto the second side panel at the interior.

Abstract: A multi-compartment bag includes a first bag wall; a second bag wall aligned and joined to the first bag wall at a first sealed side edge, a second sealed side edge, a sealed bottom edge, and an unsealed top edge; a first closure track formed in the first bag wall at the top edge; a second closure track formed in the second bag wall at the top edge and configured to mate with the first closure track; a partition seal interposing and extending parallel to the first sealed side edge and the second sealed side edge.
