Abstract: Apparatus and methods for creating multi-layered lightly-laminated provide films with increased or maintained strength. An increased level of strength is achieved by bonding adjacent layers of the multi-layer film together in a manner that the bond strength of the laminated layers is less than a strength of a weakest tear resistance of the individual first and second film layers. The inventors have surprisingly found that such a configuration of light bonding provides increased and unexpected strength properties to the multi-layer film as compared to a monolayer film of equal thickness or a multi-layer film in which the plurality of layers are tightly bonded together.

Abstract: Methods of increasing the perceived thickness and strength of a thermoplastic film include incrementally stretching thermoplastic films in the machine direction. In one or more implementations, methods of incrementally stretching thermoplastic films include reducing the gauge of the films while increasing a loft of at least a portion of the film. The methods can involve cold stretching the films and imparting rib patterns and alternating peaks and valleys into the film. The linear ribs can have alternating thick and thin gauges.

Abstract: Implementations described herein include films with maintained or decreased light transmittance despite a reduction in gauge. In particular, one or more implementations include a multi-layer film with each layer having differing opacity agents. The combination of the two different opacity agents in two different layers can have a synergistic effect that provide decreased light transmittance. Indeed, in one or more embodiments a multi-layer film with differing opacity agents in each layer has a decreased light transmittance despite a reduction in gauge and opacity agents.

Abstract: Methods of stretching thermoplastic films in the machine direction include elongating the films in the machine direction without significantly reducing the films' machine-direction tear resistance. In one or more implementations, methods of stretching thermoplastic films include reducing the gauge of the films while substantially maintaining the films' machine-direction tear resistance. The methods can involve uniformly cold stretching the films by stretching the films to a draw of about one hundred and eighty percent, or less, of the films' original length.

Abstract: One or more implementations of a multi-layered bag with reinforced seals include an outer layer or bag and an inner layer or bag positioned within the outer layer or bag. The multi-layered bag further includes a draw tape positioned near the opening of the multi-layered bag. The draw tape can allow a user to at least partially close the multi-layered bag by drawing the layers of the bag together. The multi-layered bag further includes one or more tape seals that bond the draw tape to layers of the bag. The tape seals can be reinforced and include at least seven plies bonded together. One or more implementations further include methods of forming multi-layered bags with reinforced seals.

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: The present disclosure relates to thermoplastics film, multi-film structures, and bags including enhanced physical properties. For example, one or more implementations include tailoring the physical properties of thermoplastic films by forming ribs using ring rolling in the films that extend at an angle relative to a direction in which the film is extruded (e.g., the machine direction). In other words, one or more implementations include films with a pattern of ribs extending at an acute angle to the predominate direction of molecular orientation of the thermoplastic film. The angled ribs increase the machine direction tear resistance of the thermoplastic film by intersecting any machine direction propagating tears and redirecting the tears towards the higher tear resistant transverse direction.

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.
