    Abstract: A multiple-ply thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern, when stretched or elongated and then released, can cause areas of billowing and delamination between plies of the multiple-ply thermoplastic film. The resulting billowed and delaminated areas form billow pockets for capturing liquids that can capture liquids when one of the plies is punctured.

    Abstract: The present disclosure relates to thermoplastic bags having a drawtape within a hem, where the drawtape includes a deformation pattern of a plurality of ribs and a plurality of web areas. The plurality of ribs can include ribs that extend across the drawtape in a non-parallel direction with respect to the width of the drawtape (e.g., at an angle). In some instances, the non-parallel direction causes each rib to point towards a hem hole of the hem that exposes a portion of the drawtape. The plurality of ribs can further be mirrored across an axis that corresponds to a length of the drawtape. In some cases, the ribs are formed via a structural elastic-like film (SELF) process, such as a phased SELF process that leaves a portion of the drawtape without ribs.

    Abstract: The present disclosure relates to strata 2-ply drawstring trash bags implementing a J-flap extended hem to provide increased top-of-bag strength. In one or more embodiments, the J-flap extended hem includes a 2-ply web folded back on itself (e.g., during a hem folding operation to enclose the drawstring within a hem channel). In one or more implementations, a hem seal secures the 2-ply web to an inside surface of the trash bag. At least one ply of the 2-ply web fold-over extends past the hem seal and is additionally secured to the inside surface of the trash bag via one or more hem skirt seals. For reduced material consumption in certain embodiments, the J-flap extended hem of the present disclosure imparts added strength using only one ply of the 2-ply web fold-over. In some embodiments, at least one ply of the 2-ply web fold-over includes ring-rolled portions to add top-of-bag strength.
