  • Publication number: 20200103383
    Abstract: The present disclosure relates to a thermoplastic film that includes a layer of thermoplastic material and a color indicator applied to the thermoplastic material. The color indicator can be configured to change color in response to a trigger. For example, the color indicator can change color (e.g., change from a first color to a second color) in response to a color change trigger, such as exposure to malodor particles, absorption of moisture, a length of time, or as a result of oxidation. In one or more embodiments, the thermoplastic film further includes an odor control component configured to mask, neutralize, or otherwise control malodors. The color indicator can change its color appearance as the odor control component performs to control any present malodors, thus signaling the performance of the odor control component.

  • Patent number: 10543658
    Abstract: In one example embodiment, a film includes a coextruded structure having both an extruded ribbed skin layer that includes a plurality of ribs, and a core layer. The ribs are spaced apart by a web that is integral with the ribs. The film also includes a coloring agent that is substantially more apparent in the ribs than in the web, such that a contrast in color and/or color intensity between the ribs and the web is visible.

  • Patent number: 10196176
    Abstract: Multi-layer bags may be formed to include first and second sidewalls joined along a first side edge, an opposite second side edge, and a closed bottom edge. The first and second layers may be non-continuously laminated together in discrete sections to include bonded regions in which the layers are bonded and unbonded regions in which the layers are not bonded. Such a bag may be described as a “bag-in-a-bag” type configuration in which the inner bag is non-continuously bonded to the outer bag. The inventors have surprisingly found that such configurations of non-continuous bonding provides increased and unexpected strength properties to the multi-layer films and bags.

  • Patent number: 10081169
    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.

  • Patent number: 10052844
    Abstract: Multi-layered thermoplastic films include intermittent stretched regions that are visually distinct from un-stretched regions. The stretched regions can be white, opaque, and non porous. The multi-layered thermoplastic films with visually-distinct stretched regions can be formed into bags for use as trash can liners or food storage. Additionally, methods of stretching thermoplastic films to create visually distinct stretched regions include incrementally stretching a plurality of film layers, at least one of which includes a thermoplastic material and a voiding agent.

  • Patent number: 10029437
    Abstract: In one example embodiment, a laminated film includes an extruded ribbed first film portion that includes multiple ribs, where consecutive ribs are separated by webs that are integral with the ribs. The laminated film also includes an un-ribbed second film portion, and a region of discontinuous lamination between the first film portion and the second film portion. The region of discontinuous lamination includes multiple regions where the first and second film portions are bonded together, and multiple regions where the first and second film portions are not bonded together.

  • Patent number: 9862177
    Abstract: Incrementally-stretched adhesively-laminated films include two or more film layers adhesively bonded together. At least one of the two or more film layers is incrementally stretched. The incrementally-stretched adhesively-laminated films can have maintained or increased strength parameters despite a reduction in gauge. The incrementally-stretched adhesively-laminated films can be formed into bags for use as trash can liners or food storage. Methods of forming incrementally-stretched adhesively-laminated films include cold stretching one or more of the first and second film layers and adhesively bonding the film layers together.

  • Patent number: 9790012
    Abstract: Methods of enhancing one or more physical properties of a thermoplastic film include incrementally stretching thermoplastic films in the machine direction and/or transverse direction. In one or more implementations, methods of incrementally stretching thermoplastic films include reducing the gauge of the films while maintaining or increasing a ratio of the machine direction to transverse direction resistance to tear. The methods can involve cold stretching the films and imparting rib patterns into the film. The linear ribs can have alternating thick and thin gauges.

  • Patent number: 9744706
    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.

  • Patent number: 9682801
    Abstract: Multi-layered bags include an outer layer or bag and an inner layer or bag that is shorter than the outer layer or bag. The shortened inner layer or bag can stretch or expand to the outer layer or bag when loaded with objects or otherwise strained. Such multi-layered bags can allow for a reduction in thermoplastic material without compromising the strength of the multi-layered bag. In various implementations, the inner layer or bag may be non-continuously laminated, continuously laminated, or joined only along one or more edges to the outer layer or bag. Implementations including non-continuous bonds securing the inner layer or bag to the outer layer or bag can provide additional strength to the bag. Methods of forming multi-layered bags with a shortened inner layer including inserting an inner layer within an outer layer and then joining the layers to form a bag.
