20120039550 | Incrementally-Stretched Adhesively-Laminated Films and Methods for Making The Same - 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. | 02-16-2012 |
20120064271 | Multi-Layered Lightly-Laminated Films and Methods of Making The Same - 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. | 03-15-2012 |
20120134606 | Non-Continuously Laminated Multi-Layered Bags With Ribbed Patterns And Methods of Forming The Same - Methods for creating multi-layered bags with increased or maintained strength involve forming a ribbed pattern in one or more film layers of a multi-layered bag. The method also includes non-continuously laminating the film layers of the multi-layered bag together. In one or more implementation, a transverse direction ring rolling process forms the ribbed pattern and bonds the film layers together. In one or more additional implementations, the ribbed pattern and lamination are formed separately. Still further implementations include forming network patterns one or more film layers of a multi-layered bag. Multi-layered bags formed in accordance with one or more implementations of the present invention include one or more of increased strength or reduced basis weight. | 05-31-2012 |
20120163738 | Multi-Layered Bags With Shortened Inner Layer - 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. | 06-28-2012 |
20140023829 | Multi-Ply Puckered Films Formed By Discontinuous Lamination of Films Having Different Rebound Ratios - Methods of increasing the loft of a multi-ply thermoplastic film include stretching thermoplastic films with different rebound ratios, non-continuously laminating the films together, and releasing the films to create puckers in one or more of the films. The puckers can comprise billowing of one of the films. The non-continuous laminated areas can maintain the puckers in the films. The puckers can increase the loft of the film, improve the feel of the film, and/or modify the look of the film. The loft of such multi-ply puckered thermoplastics films vary independent of the basis weight of the films. Thus, multi-ply puckered thermoplastics films with increased loft of one or more implementations can look and feel thicker while using reduced amounts of thermoplastic material. | 01-23-2014 |

20130209711 | RIBBED FILM STRUCTURES WITH VOIDING AGENT CREATED VISUAL CHARACTERISTICS - 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 voiding agent in the ribs of the skin layer. | 08-15-2013 |
20130209712 | RIBBED FILM STRUCTURES WITH PIGMENT CREATED VISUAL CHARACTERISTICS - 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. | 08-15-2013 |
20130243982 | DISCONTINUOUSLY LAMINATED FILM STRUCTURES WITH IMPROVED VISUAL CHARACTERISTICS - 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. | 09-19-2013 |

20090214141 | Closure Device Providing Visual Confirmation of Occlusion - A closure device providing a visual confirmation of occlusion. The closure device includes a first and a second interlocking fastening strips which are arranged to be interlocked over a predetermined length, at least one of the fastening strips having a surface alteration providing visual confirmation of occlusion of the closure device. The surface alteration may be a slit which opens or closes upon occlusion of said closure device. In one embodiment, the surface alteration may extend into a coextruded portion. The color of the coextruded portion is exposed when the surface alteration is open and hidden when the surface alteration is substantially closed. In another embodiment, the surface alteration may extend into an edge glow material which produces an edge glow effect when the surface alteration is open. In a third embodiment, the surface alteration may extend through an opaque side wall to expose the color of the base. The surface alteration may be located on the mating side, the non-mating side or both sides of one or both of the bases. In addition, the surface alteration may be located on the closure element. The opening or closing of the surface alteration may be achieved by a deformation in the closure device upon occlusion of the closure device. The deformation may be an inward deformation or an outward deformation on the fastening strip. This deformation may also allow a user to tactually confirm that the closure device has been occluded, even after the closure device has been occluded. The deformation may be on one or both of the fastening strips. In addition, the fastening strip may include multiple deformations. | 08-27-2009 |
20090277898 | MICROWAVABLE BAG OR SHEET MATERIAL - A microwavable material having a structure that may be used to enhance the browning and crisping, and thus improve the taste and appearance, of a food item cooked therein. The material may be in the form of a sheet material or formed as a container such as a bag, pouch, or other suitable structure. The material may comprise one or more features that help bring the material into close contact with the food item and help conform the bag around the food item. Furthermore, the material may comprise a structure that avoids substantial contact with liquid released by a food item, may have a venting system suitable for the exiting of moisture, may have a coating, a transparent surface, and when formed as a container, may have a gusseted surface. | 11-12-2009 |
