Abstract: The present disclosure relates to thermoplastic bags with enhanced dart impact resistance. In particular, in one or more embodiments, the disclosed thermoplastic bags include a first sidewall and a second sidewall joined together along a first side edge, a second side edge, and a bottom edge, while having an opening opposite the bottom edge. Furthermore, in some embodiments, the disclosed thermoplastic bags have a pattern of raised rib-like elements and web areas formed in the first sidewall. In one or more embodiments, the pattern of raised rib-like elements and web areas comprises a first motif of deformations that repeats in the pattern and a second motif of deformations interspersed with the first motif of deformations within the pattern. In one or more embodiments, the web areas lack sharp corners. The interspersed motifs and/or the lack of sharp corners can serve to increase dart impact resistance of the thermoplastic bags.

Abstract: One or more implementations of a multi-film thermoplastic bag with a grab zone of contact areas positioned in a high-touch area of the bag. For example, the multi-film thermoplastic bag includes one or more regions of a first film in contact with a second film at one or more contact areas. The grab zone regions of one or more contact areas are located in visible and high-touch areas to provide visual and tactile cues of strength and durability. Moreover, the grab zone regions of one or more contact areas serve to distribute pull and lift forces across a wider area in order to avoid common failures in high-touch areas such as over stretching, punctures, tears, and rips.

Abstract: A thermoplastic bag includes duplicative seals. In particular, in one or more implementations, a thermoplastic bag includes a first seal and at least a second seal reinforcing the same area of the thermoplastic bag. For instance, in one or more implementations, the thermoplastic bag includes multiple seals along each side edge or along the hem. If one seal fails, the other seal(s) can remain in place to prevent leaks. Thus, the duplicative seals of the thermoplastic bag can provide reinforced strength and desired aesthetics.

Abstract: A 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 provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a complex stretch profile.

Abstract: The present disclosure relates to a reinforced thermoplastic bag (e.g., comprising a bag-in-bag). In one or more embodiments, the reinforced thermoplastic bag includes a reinforced portion at a top-of-bag area where users often apply an external force to lift or carry the reinforced thermoplastic bag. In these or other embodiments, a grab-zone reinforcement insert is positioned across one or both of a hem channel region and a grab-zone along an outer surface, an inner surface, or between layers of the reinforced thermoplastic bag. In one or more embodiments, the grab-zone reinforcement insert comprises multiple layers (e.g., of a non-woven material). For example, the grab-zone reinforcement insert includes a first and second layer formed by a fold. In other implementations, the grab-zone reinforcement insert includes separate, discrete layers. In one or more embodiments, at least a portion of the grab-zone reinforcement insert is positionally affixed via a hem seal.

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: Methods of incrementally stretching thermoplastic films in the machine direction include elongating the films in the machine direction without reducing the films' machine-direction tear resistance. In one or more implementations, methods of incrementally stretching thermoplastic films include reducing the gauge of the films without reducing the films' machine-direction tear resistance. The methods can involve cold stretching the films and imparting transverse-direction extending linear rib pattern into the film. The linear ribs can have alternating thick and thin gauges. Incrementally stretched thermoplastic films can have a machine-direction tear resistance that is equal to or greater than the machine-direction tear resistance of the film prior to stretching.
