One or more implementations of a multi-film thermoplastic bag including a zone of contact areas between adjacent films with varying lamination. The contact areas comprise areas in which at least first and second thermoplastic films of the multi-film thermoplastic bag are in intimate contact and bonded together by heat and pressure. The contact areas help reinforce the bag due to increased stiffness provided by the contact areas, as well as distribute stresses/stain over more material, and thereby, help reduce tearing or other damage by stresses/strain from grasping fingers (e.g., during a grabbing motion to lift or carry) or objects being placed inside the bag. Additionally, the increased stiffness can provide a tactile feel that connotes strength to a user grasping the grab zone.

One or more implementations of a multi-film thermoplastic structure include a first film having a first appearance in contact with a second film having a second appearance at one or more visually distinct contact areas, including a continuous contact area spanning a width of the structure. In one or more implementations the multi-film thermoplastic structure comprises a thermoplastic bag and the continuous contact area forms a hem seal near a top opening of the thermoplastic bag.

One or more implementations of a multi-film thermoplastic structure include a first film having a first appearance in contact with a second film having a second appearance at one or more visually-distinct contact areas. Wherein the one or more visually-distinct contact areas, cause the first film to take on the second appearance of the second film. The visually-distinct contact areas being of a uniform gauge and configured to separate before either of the first film or the second film fails when subjected to peel forces.

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.

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.

One or more implementations of a multi-film thermoplastic structure include a first film having a first appearance in contact with a second film having a second appearance at one or more visually-distinct contact areas arranged into a text. Wherein the one or more visually-distinct contact areas, cause the first film to take on the second appearance of the second film. In one or more implementations the multi-film thermoplastic structure comprises a thermoplastic bag and text comprises a suffocation warning.

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.
