The packaging material includes a packaging material body formed into a sheet shape as a whole by welding two film sheets having an upper sheet and a lower sheet together at appropriate points; an air introduction path having the packaging material body, one side thereof serving as an air introduction port and the other side sealed; a plurality of air bags having the packaging material body while being in communication with the air introduction path, and extending in a direction orthogonal to the air introduction path; and check valves provided to respective air inlets of the plurality of air bags and preventing escaping of air having been introduced through the air introduction port and introduced into the air bags through the air inlets. The packaging material body is bent and welded at appropriate points, whereby a packaging bag for storing a packaged object is provided.

The present disclosure relates to a shock-absorbing packaging material having multi-layered air cells. Between outer covers forming air cells, an auxiliary inner cover is provided to be fused alternately and partially with the outer covers and thus form air cells of a multi-layered structure, which are alternately stacked between the outer covers. When packaging an article using the shock-absorbing packaging material, it is possible to more safely protect the article due to an enhancement in shock-absorbency through the air cells of a multi-layered structure. Moreover, the structure of the air cells of a multi-layered structure, which are alternately stacked, may effectively block heat transfer between the inside and the outside of the packaging material through portions where the air cells are connected with each other, whereby the shock-absorbing packaging material having multi-layered air cells may be useful for packaging an article which needs to be kept warm or cold.

A panel holding portion of a packaging tray according to an aspect of the present invention includes a holding recess, a panel supporting portion, a supporting foot, a panel pressing portion, and a tray supporting portion. In a state in which a display panel is held in the holding recess, a top tier tray is stacked above the packaging tray, and a bottom tier tray is stacked below the packaging tray, the supporting foot includes a first contact surface that is in contact with the tray supporting portion of the bottom tier tray, the panel pressing portion includes a second contact surface that is in contact with the display panel held in the bottom tier tray, and the tray supporting portion includes a third contact surface that is in contact with the first contact surface of the top tier tray.

An inflatable packaging element is disclosed herein. The inflatable packaging element includes a first film ply and second film ply overlayed on the first ply, and a seal pattern. The seal pattern has a plurality of seals sealing the first and second plies to each other to define an inflation chamber between the first and second plies. The inflation chamber is inflatable with and configured to contain a fluid. An aperture extends through at least one of the first or second ply, and the seal pattern separates opposite side of the aperture from the inflation chamber.

An angle protector for preventing damage to goods during transport and methods of use are provided. The angle protector includes a top end, base end, corner portion, top portion, and base portion. The corner portion includes an inside surface and an outside surface. The corner portion is positioned between the top end and the base end. The top portion extends between the corner portion and the top end. The top portion includes an arch and at least one fin. The arch includes a generally convex outside surface and a generally concave inside surface. The arch extends between the top end and the corner portion. The at least one fin extends at an angle toward the top end from the generally concave inside surface of the arch. The base portion includes an inside surface and an outside surface. The base portion extends between the corner portion and the base end.

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.

The invention is directed to a foldable and biodegradable cushioning sheet comprising a plurality of cushions, which sheet comprises a flexible base film and a plurality of cushions located on the top surface of the flexible base film; and wherein the cushioning sheet can be folded to provide a sturdy inside corner, wherein an object can be placed, such that the object is protected and if needed immobilized, for example during packing and transporting.

The invention discloses a polycondensation fixing device for a fragile article, which includes a wall shell. The wall shell is provided with a working cavity. The rear end wall of the working cavity is symmetrically provided with slide rails, and the slide rail openings. Toward the front, a sealing strip is slidably arranged in the slide rail, a locking block is provided between the seal strip and the slide rail, and suction chambers are symmetrically arranged in the lower end wall of the working chamber. There is a sealing mechanism inside, and air inlet chambers are symmetrically arranged in the left and right end walls of the working cavity. The air inlet chamber is provided with an air inlet mechanism. When the container is used, the device has a good buffering effect, and can be isolated from the air for moisture and water resistance.
