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.

Thermoplastic bags with complex stretch patterns

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.

Thermoplastic bags with duplicative seals

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.

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.

The present disclosure relates to a fiber reinforced thermoplastic bag (e.g., comprising a bag-in-bag). In one or more embodiments, the reinforced thermoplastic bag includes a plurality of fibers reinforcing a top-of-bag area where users often apply an external force to lift or carry the reinforced thermoplastic bag. In certain embodiments, the plurality of fibers is positioned across at least a portion of a grab-zone. Additionally or alternatively, the plurality of fibers reinforces a hem channel region. In particular embodiments, the plurality of fibers is positioned in between bag layers. For example, the plurality of fibers is sandwiched between an inner layer and an outer layer. In certain implementations, the plurality of fibers between layers is bonded to a particular layer, but not necessarily both layers. Additionally, the plurality of fibers can impart a variety of mechanical benefits. Further, the plurality of fibers is visually identifiable through one or both layers.

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.

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.

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.

Thermoplastic bags with phased deformation patterns

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.
