20100046860 | BAG - The bag may include a draw tape that may be used to cinch closed the opening of the bag. The draw tape may include an elastic characteristic and may be smaller in size than the peripheral distance about the opening. The draw tape in its natural contracted state may partially constrict the opening. However, the draw tape may be stretched or expanded to enable a user to dilate the opening and fold the periphery of the opening over the rim of the canister. The draw tape may then recover or constrict to grip about the rim of the receptacle to hold the bag to the canister. In one embodiment, the bag may include a pattern proximate the bag opening to allow the bag opening to be stretched over the rim of the canister. | 02-25-2010 |
20100187135 | Bag with Leak Resistant Features - A bag with flexible sidewalls defining an interior volume is provided with leak resistant features that function to absorb and retain liquids. These features include an absorbent-adhesive mixture that may be made from an adhesive and absorbent agents such as a super absorbent polymer. The absorbent-adhesive mixture can be applied on an inner surface of the flexible sidewalls in a location where it is likely to encounter liquids. The leak resistant features can also include a substrate that may be made from a non-woven material that is also applied to the inner surface of the sidewall and can be bonded to the sidewall by the absorbent-adhesive. In various embodiments, the bag can also include odor neutralizing features and/or configured with stretchable sidewalls. | 07-29-2010 |
20100195937 | BAG - A bag may include opposing first and second sidewalls of a pliable thermoplastic material that may be joined to each other along first and second side seals and a closed bottom. The sidewalls may remain un-joined along their top edges to form an opening into which trash and other items may be deposited. When the bag is placed in a trash receptacle, the un-joined top edges may be folded over the rim of the receptacle to secure the liner to the receptacle. To assist with securing the bag to the receptacle, the side seals may be directed to converge partially toward each other thereby forming a throat in the interior volume proximate the opening. When the top edges are folded over the receptacle rim, the throat may grip the receptacle. The bag may include a pattern between the converging portions. The bag may include a retention strip between the converging portions. | 08-05-2010 |
20100303388 | Draw Tape Bag - The bag may include a draw tape that may be used to cinch closed the opening of the bag. The draw tape has at least one stretched elastomeric strip attached to the draw tape in an extended condition. The draw tape may be smaller in size than the bag sidewalls. The draw tape may include an elastic characteristic, such as patterned ribs. In one embodiment, the roll of bag is kept under tension to maintain the elastomeric strips in a stretched condition. | 12-02-2010 |
20110117307 | Discontinuously Laminated Film - Polymer films may be discontinuously laminated by processes such as adhesive bonding, ultrasonic bonding, embossing, ring rolling, and strainable network formation. The films may be prestretched under cold process conditions before lamination. The laminates have superior properties such as tear strength. The laminates may be incorporated into bags, such as trash bags. | 05-19-2011 |
20110317945 | Bag - A thermoplastic bag may include a sidewall that may have a plurality of first and second ribs formed therein. The first ribs may be longer in length but shorter in height than the second ribs. The second ribs may be arranged in discrete networks that appear superimposed over the first ribs. The second ribs may normally remain in a bent-over configuration. When a force is applied, the second ribs may expand the area of the sidewall so that the bag may easily accommodate large objects. To produce the bag, a thermoplastic web may be directed between opposing first and second rollers. One of the rollers may include ridges that may have first and second segments of differing heights that correspond to the differing heights of the first and second ribs. The formation of the first ribs may increase the width of the web. | 12-29-2011 |
20120033900 | Non-Continuously Laminated Multi-Layered Bags - 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 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. | 02-09-2012 |
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 |
20120063704 | Multilayer Plastic Film - A thermoplastic bag suitable for use as a liner for a garbage canister or trash receptacle may be made from a multi-layered thermoplastic web material. The multi-layer web material may include a first layer and a second layer adjacent to the first layer. Under typical conditions, the layers may tend to block or adhere together to remain in their adjacent position. However, the layers may delaminate and separate from each other when sufficient forces are applied. Delamination of the layers allows the layers to move with respect to each other when the force is applied. The delaminating of the layers absorbs energy which may increase tear and puncture resistance. | 03-15-2012 |
20120063706 | Multi-Layered Bags With Discrete Non-Continuous Lamination - 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. | 03-15-2012 |
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 |
20130051710 | Stretched Films with Maintained Tear Resistance and Methods for Making the Same - 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. | 02-28-2013 |
20130059711 | Method For Inserting A First Folded Film Within A Second Folded Film - Methods for inserting a folded film into another folded film include combining the films without unfolding or folding either of the folded films. In particular, one or more implementations of a method of combining folded films involves directing a first folded film in a first direction and separating first and second halves of the first folded film. The method also involves directing a second folded film in a second direction generally perpendicular to the first direction. Additionally, the method involves inserting the second folded film between the first and second halves of the first folded film. Furthermore, the method involves redirecting the second folded film into the first direction while between the first and second halves of the first folded film. | 03-07-2013 |
20130059712 | Apparatus For Inserting A First Folded Film Within A Second C-Folded Film - Apparatus for inserting a folded film into another folded film include combining the films without unfolding or folding either of the folded films. In particular, one or more implementations include a spreader bar configured to separate layers of a first folded film.

Furthermore, the apparatus can include a direction change bar configured to change the direction a travel of the second film while the second film is positioned between the layers of the first folded film. | 03-07-2013 |
20130094787 | BAG WITH IMPROVED FEATURES - The bag for receiving refuse may include a bag body, the bag body including an inside surface, an outside surface, and a rim defining a mouth. The bag may also include a first strip of material disposed on the inside surface of the bag body proximate the rim. The strip may include an inside surface, an outside surface that faces the inside surface of the body, a top edge, and a bottom edge. The bag may also include a front wall, a back wall, and a hem, the hem including a drawstring. The strip may include a printed design. The design could be letters, numbers, pictures, writing, or any other design. When the bag is inserted into a trash receptacle such that the rim of the bag is folded over the rim of the receptacle, the printed design is visible from outside the receptacle. | 04-18-2013 |
20130188889 | Trash Bag With Inner Bag - Trash 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 to form an outer bag. A second inner bag may be inserted within the first bag to form a “bag-in-a-bag” type configuration in which the inner bag is bonded to the outer bag along side seals. When the outer and inner bags are formed primarily from LLDPE thermoplastic resin using a blown film process, the inventors have surprisingly found that such configurations provide increased and unexpected strength properties while using less material. | 07-25-2013 |
20130188891 | CONTINUOUS PROCESS FOR TRASH BAG WITH INNER BAG - Trash 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 to form an outer bag. A second inner bag may be inserted within the first bag to form a “bag-in-a-bag” type configuration in which the inner bag is bonded to the outer bag along side seals by a continuous process. The bags may also be bonded together along the hem and the draw tape. When the side seals of the inner bag and the outer bag are sealed together by a continuous rather than a reciprocating process, the inventors have surprisingly found that such seals require carefully controlled process conditions to prevent inadequate seals. | 07-25-2013 |
20130202229 | MULTI-LAYERED THERMOPLASTIC BAG WITH REINFORCED SEALS AND METHODS OF MAKING THE SAME - 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.

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 |

20140378286 | METHODS OF MAKING MULTI-LAYERED BAGS WITH ENHANCED PROPERTIES - Methods for creating multi-layered incrementally-stretched and incrementally-laminated bags with increased or maintained strength are described herein. An increased level of strength is achieved by bonding adjacent layers of a 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. | 12-25-2014 |
