Abstract: One or more implementations of a thermoplastic bag with a grab zone of deformations including raised rib-like elements positioned in a high-touch area of the bag. For example, the thermoplastic bag includes a hem skirt non-continuously laminated to a sidewall by one or more raised rib-like elements. The grab zone regions of one or more raised-rib-like elements 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 raised rib-like elements 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: 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: 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: 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: A thermoplastic bag includes structures that direct liquid away from areas of the bag more susceptible to failure and leaking. For example, one or more implementations include seals that direct liquid introduced into the bag away from corners of the bag. Additionally, one or more implementations include an insert positioned within the bag between the liquid directing structures such that the liquid directing structures direct liquid to the insert. In one or more implementations, the insert comprises an absorbent material. Thus, the liquid directing structures can direct liquid to a liquid absorbing insert.

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: Thermoplastic films and bags include gradient patterns of post-formation deformations. The gradient patterns of post-formation deformations can provide a connotation of strength. Additionally, the gradient pattern of post-formation deformations can provide different areas of the films or bags with different physical characteristics such as tear resistance, puncture resistance, elasticity, etc.

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: One or more implementations of a multi-layer film include a first layer non-continuously bonded to a second pigmented layer. The multi-layer film includes an unexpected appearance differing from the appearance of the pigmented layer. In one or more embodiments, the multi-layer film includes a metallic appearance despite the pigmented layer being devoid of metallic pigment. The multi-layer film also includes areas that are visually distinct from areas of the film with the unexpected appearance. The visually-distinct areas comprise areas in which the first layer non-continuously is in intimate contact with the second pigmented layer. The visually-distinct areas have the appearance of the pigmented layer or another appearance. One or more implementations also include methods of making multi-layer films and bags with an unexpected appearance and visually-distinct areas.
