A stitchless highly oriented polypropylene fabric bulk bag of the type that can hold 500 to 5000 pounds (226.7 to 2268 kilograms) of bulk material includes a highly oriented polypropylene fabric top, body and bottom, with a heat fused joint providing an air tight connection between the top and body, and another air tight heat fused joint connecting the body and bottom. A fill spout and discharge tube may also be provided with an air tight heat fused joint connecting the fill spout to the top and another air tight heat fused joint connecting the discharge spout to the bottom. Heat sealing machinery include heat seal bar assemblies that can self-align during heat-sealing to apply even pressure to all areas being heat sealed. A heating element is of single piece construction and can include end coupler portions as part of the single piece construction. Carrier plates used in a heat-sealing assembly line guide parts placement, provide quality checks for parts placement, and tooling set-up for machinery.

A bottom and discharge assembly for a flexible fabric bulk bag of the type having heat sealed joints includes a piece of reinforcing fabric positioned under a heat sealed joint of a bottom portion and a discharge tube, around a periphery of a discharge tube opening and bottom opening that are each substantially square, wherein the reinforcing fabric prevents bag failure at or about at corners of the bottom opening and discharge tube opening. The assembly can be formed by overlapping the reinforcing fabric, discharge tube, and bottom portion so that the bottom is heat sealed to both a portion of the discharge tube fabric and a portion of the reinforcing fabric and wherein a portion of the reinforcing fabric is under the discharge tube and bottom joint, and wherein the discharge tube fabric and reinforcing fabric are not joined together.

A liner bag for, for example, a flexible intermediate bulk container (FIBC) includes a body portion formed by at least two sheets. The body portion has a first end and a second end defining a cavity therebetween. The first end has an opening for receiving a product. The liner bag also includes at least one seal (e.g., a vertical seal) joining the two sheets. The liner bag further includes at least one polymer flange secured to the two sheets and extending outward from the vertical seal to provide at least one fastening location to secure the liner bag to the container.

A fabric bulk bag and a method for constructing the same, the bag including a continuous sidewall, a top portion, and a bottom, all defining a bulk storage space therein; the bottom further comprising eight sides which define an octagonal shape having an enlarged footprint so that the bag wall is sewn to the bottom in less time than a round shaped bag, yet when filled stands more upright with less tendency to lean than the current square shaped bags thereby providing a safer more dependable stacking bulk bag. In the method of producing the fabric bulk bag, the bag is constructed in less time than the prior art round bottom bags, uses less wall fabric than prior art square bottomed bags and when constructed and filled, supports itself more stable on a floor or pallet because it provides substantially more base for the product to rest on. In other embodiments, the bag would be multi-sided with greater than four sides.

Embodiments of the present disclosure are directed to multilayer silo bags that may include a tube comprising at least two layers, a first open end, a second open end, and a first region and a second region disposed between the first and second end. One M or more of the at least three layers may comprise an ethylene/alpha-olefin interpolymer having a density of 0.90 g/cc to 0.965 g/cc and N an I.sub.2 of 0.1 to 6.0 g/10 minutes, a low density ethylene-based polymer having a density of 0.917 g/cc to 0.935 g/cc and an I.sub.2 of 0.1 to 2.0 g/10 minutes, or combinations thereof. The first region may have a thickness of at least 10% greater than a thickness of the second region. The first region may have a surface area that is at least 50% of an overall surface area of the multilayer silo bag.

The device relates to transportation and storage of bulk cargoes and comprises a vessel with upper charging opening and lower discharging opening, bearing framework and discharging mechanism, the device being further provided with soft sling load distribution ring, which passes through additional external loops of the main slings and alternately through additional loops along the upper perimeter of the cylinder, which, in turn, are embodied in the form of the load distribution triangle. The device provides improving convenience of handling multi-tonnage bulk cargoes as well as improving container reliability in use.

A flexible tank is used to transport liquids or semi-liquid material in a shipping container on a railroad car. It has an inner tank and at least one end closure with alternating interlaced hollow loops from two separate exterior layers. A nylon rope or similar securing element is passed through the hollow loops to use the exterior layers in an end closure to constrain the inner tank. An end flap may be welded to an exterior layer and positioned between the inner tank and the end closure. The hollow loops may be formed by folding over the exterior layers and cutting out complementary portions so the loops are in an alternating interlaced pattern. Capacity bands located around the periphery of the flexible tank suppress expansion of the flexible tank at their respective locations.

The present disclosure is a soft-shell cargo container that is ideal for “do-it-yourself” transport. The cargo container, which may be useful in a pickup truck bed, includes a single piece of a flexible shell material that defines a base panel, a front wall panel, back wall panel, two side wall panels, a top cover panel, and a tailgate panel. The cargo container is flexible and therefore adaptable to cover bulky or awkwardly shaped cargo. The cargo in the cargo container can be secured via interior fasteners, like loops, hooks, straps, and dividers. The cargo container can also be waterproof, fire retardant, puncture proof, and lockable. Thus, the cargo container protects belongings therein from weather damage, debris, and theft.

A packaged article is composed of a bulk bag having a top end and a bottom end. Further included is a pallet having a first side and a second side. Also included are an outer bag having a first closed end and a first open end and a heatshrink bag having a second closed end and a second open end. The first closed end of the outer bag is between the bottom end of the bulk bag and the first side of the pallet. The first open end of the outer bag is gathered over the top end of the bulk bag to enclose the bulk bag within the outer bag. The second closed end of the heatshrink bag is proximate to the top end of the bulk bag and the second open end contacts the second side of the pallet.
