The present disclosure provides a packaging structure. The packaging structure may include a sheet and a film. The sheet may include a base plate and a first side plate, a second side plate, a third side plate, and a fourth side plate. The film may at least include a first fixed part and a second fixed part. The first fixed part and the second fixed part may be fixedly connected with at least two side plates of the first side plate, the second side plate, the third side plate, and the fourth side plate, respectively. The packaging structure may achieve the purpose of stretching the film through the folding of the plurality of side plates, so that the film and the bottom plate may form a packaging space to effectively package and fix an object, thereby improving the reliability of transportation.

A sack for mailing at least one item or for dunnage is provided. The sack is formed by two facing panels sealed along a perimeter. Each panel is at least one-ply and the ply has a layer of paper having a grammage from 35 to 450 g/m.sup.2 and a film of an extruded or laminated polymer covering one face of the layer of paper.

A container for transporting beverage has at least one part made of a sandwich structural laminate. The sandwich structural laminate has a PU and/or PET foam core, a resin outer skin, and a resin inner skin.

A shock absorbing device to protect cryogenically frozen biological material includes an outer sleeve and a foam sleeve. The outer sleeve defines an interior volume and has an opening configured to pass a biological material container into the interior volume. The foam sleeve is in the interior volume and has an opening and an interior cavity. The opening of the foam sleeve is aligned with the opening of the outer sleeve to pass the biological material container into the interior cavity. In another embodiment, the shock absorbing device includes a first layer, a foam layer, and a liner layer to retain the foam layer. A first side of the foam layer is adjacent and facing a second side of the first layer. A first side of the liner layer is adjacent and facing a second side of the foam layer.

A shipping system for shipping planar substrates includes a plurality of planar substrates stacked to form a pack and a plurality of interleaving material including substantially spherical beads positioned between the substrates of the pack and configured to carry a load. Substantially all of the beads have a diameter within 25% of D.sub.max, where D.sub.max is a diameter corresponding to a size of an opening of an upper limit sieve used in the shipping system. Also disclosed are a spacer for use in a shipping system for shipping planar substrates, a wrapped system for shipping planar substrates, a method of wrapping a system for shipping planar substrates, and a powder applicator.

A bottom surface member of a container defines an xy-plane, and a side surface member defines an xz-plane and aan yz-plane. A protective member includes a receiving part that has a first receiving surface parallel to the xz-plane and a second receiving surface parallel to the yz-plane, and a supporting part formed with the receiving part. The supporting part has a first flat plate section parallel to the xz-plane, a second flat plate section parallel to the yz-plane, and a third flat plate section parallel to the xy-plane. The receiving part has a fourth flat plate section that has the first receiving surface and is parallel to the xz-plane, a fifth flat plate section parallel to the yz-plane, a sixth flat plate section facing the fourth flat plate section with a gap therebetween, and a seventh flat plate section that has the second receiving surface.

A container in a rectilinear configuration has an interior surface, an exterior surface, and a plurality of planar sections. A plurality of pneumatic panels are attached to at least some of the sections. A control assembly has a first member to indicate when the pneumatic panels are inflated, a second member to deflate the pneumatic panels, and a valve to receive pressurized air from a source to inflate the pneumatic panels.

A container includes: a storage member having a bottom-surface member and a side-surface member; and two protectors disposed at two corners adjacent to each other, the two corners belonging to four corners of a storage space. Each of the two protectors has a support portion detachably fitted in a corresponding one of two cuts, a first reception portion having a first reception surface facing an end surface of a housed object, and a second reception portion having a second reception surface facing an end surface of the housed object. The first and/or second reception portion is integral with the support portion. The second reception portion has, in at least a part adjacent to a bottom surface, an evacuation portion in which a distance between the second reception surface and a side surface of the side-surface member facing the second reception surface increases along with approach to the bottom surface.

A bottom surface member of a container defines an xy plane, and a side surface member defines an xz plane and a yz plane. A protection member includes a receiving portion having a receiving surface parallel to the xz plane and a support portion integrally formed with the receiving portion. The receiving portion includes a first flat plate portion that includes the receiving surface and is parallel to the xz plane. The support portion includes a contact portion that is in contact with a side surface of the side surface member and a second flat plate portion parallel to the yz plane.

A storage container includes: a storage portion having a rectangular bottom portion, a side wall, and a hollow region; positioning members positioning a rectangular plate-like structural body inside the hollow region; positioning members positioning a rectangular plate-like structural body inside the hollow region; and grooves formed in the storage portion, each of the grooves being formed in the inner side surface at an inner corner of the bottom surface, and two of the grooves being formed at two inner corners adjacent to each other. Each of the positioning members is detachably fitted into the storage portion into corresponding one of grooves. Each of the positioning members includes a joint member in contact with one of the grooves and a contact member detachably fitted into each other. The contact member includes an engaged portion, a contact portion, and an intervening portion integrally formed with the contact portion.
