Abstract: Thermoplastic bags with phased deformation patterns are described. In particular, one or more implementations comprise thermoplastic bags with ring rolling, SELFing, or other deformation patterns phased or aligned relative to the sides of the bags. The phased deformation patterns can allow for reducing or eliminating deformation patterns in areas of the thermoplastic bag in which side seals or other seals are formed. Additionally or alternatively, the phased deformation patterns can provide for zones that provide differing properties (e.g., functional or aesthetic). Such zones can vary aligned along a width of the thermoplastic bag and optionally also vary along a height of the thermoplastic bag. The differing zones can provide the thermoplastic bags with phased deformations that provide leak prevention, liquid containment, and other benefits.

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: One or more implementations of a multi-film thermoplastic bag with a conjoined hem channel. For example, the multi-film thermoplastic bag includes a multi-film hem channel. Bonds secure the layers of the hem channel together so as to prevent a drawtape from inverting or bunching an inner layer of the hem channel during cinching. The bonds are thus located in a hem channel of a multi-film thermoplastic bag so as to reduce an amount of mechanical engagement between the films of the multi-film thermoplastic bag and another thermoplastic film such as a drawtape. In one or more implementations, a grab zone of the multi-film thermoplastic bag also includes bonds in the form of contact areas to provide tactile and visual cues of strength in the grab zone.

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.
