A cushioning member includes a cushioning material arranged between a side surface of an object and an exterior box and a positioning member for positioning of the cushioning material with respect to the object. The positioning member includes a holding portion that holds the cushioning material, an engagement portion engaged with an upper surface of the object while the cushioning material held by the holding portion is located at a position set in advance in the side surface of the object, and a coupling portion that couples the holding portion and the engagement portion to each other.

Cushioning member, packing body, and packing method

A cushioning member includes: an accommodating bag portion that accommodates a medium; a first fusing portion that defines the accommodating bag portion such that the accommodating bag portion is provided with an opening; a check valve having a first end located inside the accommodating bag portion and a second end located outside the accommodating bag portion, and provided at the opening; a second fusing portion that is immediately adjacent to the first fusing portion on those external sides of the check valve which are opposite in a direction intersecting a direction in which the check valve protrudes from the accommodating bag portion, and defines a channel that communicates with the opening; and a third fusing portion that is connected to the second fusing portion and seals the channel, the third fusing portion being provided across a portion of the check valve that protrudes from the accommodating bag portion.

Cushioning member and method for manufacturing cushioning member

A cushioning member includes a medium-filled cushioning component and a surrounding member. The medium-filled cushioning component includes a first cushioning portion and a second cushioning portion. The surrounding member includes a first tubular portion, a second tubular portion, and a connecting portion that connects an end of the first tubular portion in a direction parallel to a first central axis and an end of the second tubular portion in a direction parallel to a second central axis. The connecting portion is bendable such that a posture of the first tubular portion and the second tubular portion is changed between a parallel posture in which the first central axis is parallel to the second central axis and an intersecting posture in which the first central axis intersects the second central axis.

Cushioning member, method for manufacturing cushioning member, and packing body

A buffer member includes: a resin sheet welded in a bag-like shape; and a medium sealed in the resin sheet, wherein the resin sheet includes a plurality of buffer areas each having a shape extending longitudinally in a first direction and arranged adjacent to each other in a second direction orthogonal to the first direction, each buffer area of the plurality of buffer areas includes a first buffer chamber having a shape extending in the first direction, a second buffer chamber having a shape extending in the first direction and formed at a position separated from the first buffer chamber in the first direction, and a connecting flow passage connecting the first buffer chamber and the second buffer chamber.

Buffer member and buffer member forming material

A packaging material includes: an outer box that accommodates an article to be packaged; and a cushioning material including: a sealed bag body with gas confined inside; a partition that divides an inside of the bag body into a first chamber and a second chamber each in an equal volume; and a ventilation passage communicating the first and second chambers, the cushioning material being disposed in a gap between an outer surface of the article and an inner wall of the outer box.

Packaging material

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.
