This invention relates to inner-plies for bulk-bags that surprisingly offer not only high thermal resistance, but also high flex-crack resistance. This invention also relates to such bulk-bags made for packaging of flowable materials, aseptic or otherwise, and the process for improving their flex-crack and thermal resistance. Preferably, the packaging is aseptic. More specifically, the inner-ply of the invention comprises a resin blend comprising the Exceed XP resin; an LDPE resin or an ethylene--olefin copolymer (EAO copolymer); or a blend of said LDPE resin and said EAO copolymer, with flex-crack resistance improved in both machine direction and transverse direction, in conjunction with an improved thermal resistance. Thus, in addition to possessing good flex-crack resistance, the bulk-bags can withstand steam sterilization and/or aseptic packaging conditions.

A lightweight shipping container includes two parallel side walls each having a top rail and secured on the opposite side to bottom rails of a floor frame, coupled to one another by a floor, secured to a multiplicity of cross-beam members. A front end assembly is secured to one end of the top and bottom side rails and a door end assembly opposite the front end assembly is secured to an opposite end of the top and bottom side rails. The container further includes a roof secured to respective ones of the top rails of each of the two side walls. The floor includes a metallic cellular panel including a metallic cellular core of multiple polygonal cells, each including opposing horizontal walls coupled to one another at each distal end by at least one perpendicularly intersecting wall of half thickness as that of the opposing horizontal walls.

A thermally insulated panel includes a first skin, a second skin spaced apart from the first skin, and a core that is disposed between and bonded to the first skin and the second skin such that the core transfers loads between the first skin and the second skin. The core includes a porous filler material that has a vacuum drawn therein such that the core resists transfer of thermal energy through the panel. A cargo container including thermally insulated panels and a method of manufacturing the thermally insulated panels are also disclosed. In addition, a method of repairing a vacuum insulated panel is disclosed.

An improved reefer wall panel having better foam adhesion includes purposefully spaced gaps in the looped sections to be foamed. Such spaced gaps may extend horizontally, vertically, diagonally or in combinations of directions. These gaps (random or patterned) may be applied to the whole of a reefer panel or to just the more vulnerable lower sections where traffic impact during loading/unloading is more common and/or where delamination is known to occur more frequently. A method of reefer panel manufacture with such spaced gaps is also disclosed.

According to aspects of the present disclosure, a process of fabricating a unitized container panel is disclosed. The unitized container panel is fabricated by forming a multilayer insulated panel, which has opposing external layers and an intermediate layer therebetween. The intermediate layer is a combination of an insulation material (e.g., vacuum insulated panel, aerogel, etc.), and a buffer material (e.g., a foam board, polystyrene, fiberglass, minerals, plastic, natural fibers, wood, plastic, etc.) that bounds the insulation material. Pressure is applied about the multilayer insulated panel for a predetermined process time, causing the external layers to encase the intermediate layer. After elapse of the predetermined process time, the pressure is released about the multilayer insulated panel, thereby resulting in a unitized container panel.

The present invention provides a container having a bottom frame; the bottom frame includes a pair of bottom side rails, a plurality of cross member and a floor. The pair of bottom side rails are located at both sides of the bottom of the container respectively. The plurality of cross members are located between and connected to the bottom side rails. The floor is laid on the cross members and extends along the longitudinal direction of the container; the floor comprises a first steel floor. The bottom frame further includes a grit discharging structure configured to discharge the grits, collected on the upper surface of the first steel floor after the inner surface and/or the welding seam on the inner surface of the container is shot-blasted, from the container. The container according to the present disclosure could allow for discharging the sand collected on the upper surface of the first steel floor after shot-blasting the inner surface and/or the welding seam on the inner surface of the container, thus facilitating the shot-blasting.

An improved fabric backing for the manufacture of glass-reinforced thermoplastic panels that exhibits significantly greater foam adhesion than its scrim counterpart. That fabric backing includes a plurality of looped section extending upwardly (and inwardly) from its base for enhancing adhesion thereto. The combination is subjected to lamination for making an improved glass-reinforced thermoplastic interior wall panel. That wall panel can be used in a storage unit, such as a refrigerated trailer, railcar, shipping container and/or box truck.

A lightweight shipping container includes two parallel side walls each having a top rail and secured on the opposite side to bottom rails of a floor frame, both bottom rails being coupled to one another by a floor, which is secured to and resting on a multiplicity of cross-beam members of the floor frame. A front end assembly is secured to one end of the top and bottom side rails and a door end assembly opposite the front end assembly is secured to an opposite end of the top and bottom side rails. The container further includes a roof secured to respective ones of the top rails of each of the two side walls. The floor includes a metallic cellular sandwich panel formed by a frame defining an interior portion of the panel and including a metallic cellular core of a multiplicity of metallic polygonal cells, and a skin covering both the frame and the metallic cellular core.

A composite molded cargo body panel including a core, an interior skin secured to a first side of the core having a thickness, and exterior skin secured to a second side of the core, and a plurality of recesses. The plurality of recesses are dispersed along a first direction at intervals in the interior skin, with the core thickness at each of the plurality of recesses being reduced compared to a maximum core thickness, and each of the plurality of recesses defines a support surface. A pocket is formed in each of the plurality of recesses, with the core thickness at the pocket being less than the core thickness at each of the plurality of recesses. A plurality of logistics inserts are attached to the respective support surfaces of the plurality of recesses so that, at each of the plurality of recesses, the logistics insert extends across the pocket.

A curtain closure for the cargo opening of an air cargo container and the air cargo containers that have the same. The curtain closures include a fabric layer, and at least one of an insulating layer or a reinforcing layer attached to the inside of the fabric layer.
