An air cushioning material includes: a belt-like part between a first and second air cells into which air is sealed, wherein side edges of the first and second air cells are connected to each other via the belt-like part; and an air flow passage that is formed in the belt-like part and communicates the first and second air cells, wherein at least a part including the air flow passage in the belt-like part is in a shape folded in a way from the first air cell to the second air cell.

A tray for carrying a display panel is disclosed, and the tray includes a base configured to support the display panel, supporting members on the base and each having an inner surface corresponding to two adjacent sides of each of corner portions of the display panel, and buffering members coupled to the inner surface of each of the supporting members and configured to contact the two adjacent sides of the display panel, wherein the buffering members are spaced apart from the inner surface of each of the supporting members by a set distance.

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.

The present invention provides a jointed package corner protector, which includes corner plates (1) each of which is formed, in two opposite, upper and lower, ends thereof, with first through holes (11) that are perpendicular to a lengthwise direction of the corner plates (1) and a joint sheath (31) that is formed with second through holes (311) that correspond to the first through holes (11) formed in an upper end of a lower-side corner plate (1) of two corner plates (1) that are arranged adjacent to each other as being respectively set at upper and lower sides and the first through holes (11) formed in a lower end of the upper-side corner plate (1) so that button fasteners (33) may be set to penetrate through corresponding ones of the first through holes (11) and the second through holes (311) to connect the two adjacent corner plates (1) of the upper and lower sides to the joint sheath (31), whereby easy variation of a length of the package corner protector can be achieved accommodate stacked heights of different package specifications of display devices so as to be economic and practical and help improve manufacturing efficiency.

A packing member attached to an article to be packed, which is accommodated in a package box, to absorb an impact applied to the article, including: a first supporting part; a second supporting part; and a shock absorbing member connected to the first supporting part and the second supporting part. One of the first supporting part and the second supporting part is disposed so as to be partially in contact with the article in a state in which an impact is not applied. When an impact is applied, the shock absorbing member deforms to absorb the impact.

Wrapped paperboard packaging is described. In one independent aspect, a packaging structure, such as, for example, an edge protector, a corner board, etc., may generally include a first ply having a first width, a second ply having a second width wider than the first width, and a third ply having a third width wider than the second width. The second ply is wrapped around ends of the first ply, and the third ply is wrapped around the first ply and the second ply. The third ply overlaps at a portion (e.g., an intermediate portion, an apex, etc.) of the packaging structure.

The present disclosure discloses a stop block and a display panel packaging structure, the stop block includes a support and at least one buffer, and the support includes at least one mounting portion and at least one fixing portion; the buffer is attached to and covers the fixing portion.

An apparatus according to one embodiment includes a base having at least three mounting points on an upper surface thereof, an elastic block above each of the mounting points, and an elastic panel coupled to, and extending along, the upper surface of the base in a region between the mounting points. An apparatus according to another embodiment includes a base having at least three mounting points on an upper surface thereof, an elastic block above each of the mounting points, and at least two elastic pads positioned in recesses in the upper surface of the base. An apparatus according to another embodiment includes a base having at least three mounting points on an upper surface thereof, and an elastic panel coupled to, and extending along, the upper surface of the base in a region between the mounting points. The apparatus further includes at least two elastic pads.

A packing buffering device adapted to surrounding a plate device includes a first hollow connecting rod having a first body, a first connecting portion, and a first fixing portion and a second hollow connecting rod having a second body, a second connecting portion, and a second fixing portion. The first connecting portion and the first fixing portion are respectively extended and bent from two opposite ends of the first body and in contact with the frame of the plate device. The second connecting portion and the second fixing portion are respectively extended and bent from two opposite ends of the second body and in contact with the frame of the plate device. The first body and the second body are above the plate device and not in contact with the plate device. The distance between the fixing portions is less than the distance between the connection portions.

A composite material and structure. The structure has a folded sheet having a rigid inner layer sandwiched between flexible outer layers. The sheet has an undulated shape with alternating summit and valley portions. Intermediate portions each extend between adjacent summit and valley portions. At least one score line extends through at least one of the flexible outer layers. The sheet is folded about the at least one score line. A method of forming a structure from a sheet having an undulated shape.
