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.

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.

A container is provided. The container comprises a cover, a base, and a body, which includes one or more spine structures and one or more door panels which may open and allow substantially lateral access to the interior of the container. The one or more door panels may be secured in a closed position by a latch mechanism. In a first mode, the latch mechanism is not released. In a second mode, the latch mechanism is released. The first mode and the second mode may operate concurrently and can be accessed separately via different mechanisms. A switch mechanism may alternate between the first mode and the second mode. Alternatively, a pedal includes a first pedal mechanism corresponding to the first mode and a second pedal mechanism corresponding to the second mode.

A portable waste disposal bag includes a generally round bottom section, and a generally cylindrical side section that encircles the bottom section and is attached by stitching to the bottom section. The bag also includes at least two lifting straps which are each attached by stitching to the side section. The bottom section, side section and the two lifting straps are each made from a single piece of flexible material such as woven polypropylene. The bottom section and side section form a primary waste holding section configured to hold waste products and which forms means for evenly distributing the weight of an aggregate amount of the waste products held in the primary waste holding section. The means for evenly distributing the weight is configured to be deformable into an overall generally round shape during lifting of the waste disposal bag off of a surface.

A system including a liner implement that is configured to provide a lining for at least a receptacle, the liner implement includes an upper edge component having an outer surface portion and an inner surface portion. A retention strip implement engages the upper edge component, to tighten the upper edge component around an upper opening of the receptacle. A first end segment of the retention strip implement is configured to engage the outer surface portion of the liner implement. A second end segment is configured to engage the inner surface portion of the liner implement being operable for tightening the upper edge component around an upper element of said receptacle. An adhesive free area is configured to be operable for grasping during the engagement of the second end segment adhesive with the inner surface portion of the liner implement upper edge component.

A self-loading receptacle liner apparatus has a pair of parallel tubes, each with a longitudinal slot extending the length of the tube. The slot center widens to a notch. The tube ends are attached together by two elastic bands with the slots facing each other. Each of a nested set of liners has a drawstring within a passage at the top of the liner and accessible through an opening in the passage. The stacked liners passages are slid into the slot until the drawstring openings align with the notch. The stacked liners are placed in the receptacle, and the tubes pulled apart until they straddle the receptacle opening and placed against the outside of the receptacle. When the upper-most liner is full, the drawstrings are pulled from the notch to cinch the top of the liner, simultaneously pulling the liner from the slots, leaving the next liner ready for use.

A convertible bag is provided. It may include a bag front, a bag back, a drawstring retention compartment, and at least one drawstring. The bag front may include a front perforation, a front part of the drawstring retention compartment, and a mailer front top with a top flap. The bag back may include a mailer back top, a back perforation, and a back part of the drawstring retention compartment. The convertible bag may be configured for converted from a packaging mailer configuration to a drawstring bag configuration. In the packaging mailer configuration, the top flap of the mailer front top may be folded over and secured to the mailer back top to close the convertible bag. In the drawstring bag configuration, the convertible bag may be configured to be cinched closed by pulling a portion of the at least one drawstring out of the drawstring retention compartment.

The present invention relates to improvements for the manufacturing of a wave-cut bag of polymeric film, more specifically a wave-cut bag with a body having improved shock, tear and puncture resistance. The polymeric film has an embossed pattern of a plurality of embossed regions that are comprised of a plurality of parallel, linear embosses. Further disclosed is a process for intermittently applying the embossed pattern to a collapsed tube of a blown film extrusion process. The collapsed tube with the intermittently applied embossed pattern is particularly well suited for constructing wave-cut trash bags with the embossed pattern applied to a central body of the wave-cut bags.

A flexible container for packaging waste including an inner envelope delimiting an internal volume (V) for receiving and housing the waste. The container includes a bottom wall, a top wall and at least one side wall linking the bottom and top walls, and the inner envelope includes, in the top wall, an opening that can be opened or closed using a fastener system, in which at least one flap is fixed to the inner envelope in at least one first fixing zone situated in a peripheral part of the top wall of the inner envelope, and at least one reinforcing band is fixed to the inner envelope and/or to the flap, disposed at least in a zone defined by the first fixing zone.

A liner for an aircraft waste bin includes at least one polyimide film welded to form an interior space with an opening defined at one end of the interior space configured for passage of waste into the interior space. A system for aircraft waste can include an aircraft waste bin defining a bin interior with a bin opening in one end, and a liner as described above can be included, wherein the liner is seated in the bin interior with the liner opening aligned with the bin opening for receipt of waste. A method of disposing of waste in an aircraft interior includes collecting waste into a liner within a system for aircraft waste. The method includes removing the liner from the system for aircraft waste.
