A packaging device, made from a packaging material comprising an inner structural material (1) and an outer layer material (2), wherein said inner structural material (1) is a hollow material, and said outer layer material (2) is adhered to the outside surface of said inner structural material (1), the packaging device comprising an inner structure (1) formed by folding said inner structural material (1) and an outer layer provided on the outside surface of said inner structure. A manufacturing method of the packaging material comprises producing a middle structural material comprising a cavity or channel, and sandwiching the middle structural material with an outer face material and an inner face material to yield said hollow material; and attaching the outer layer material onto an outer surface of the hollow material.

Bei einem maschinell gefertigten dreidimensionalen Verpackungserzeugnis bestehend aus einem auf eine vorbestimmte Weise umgeformten Abschnitt einer ein- oder mehrlagigen Papierbahn, der zwei sich in Bahnrichtung erstreckende Längsränder, zwei den Papierbahnabschnitt in Bahnrichtung begrenzende Endränder und einen sich parallel zu den Längsrändern, in Bahnrichtung erstreckenden Mittelbereich umfasst, ist vorgesehen, dass zumindest ein Längsrandstreifen des Papierbahnabschnitts längs dessen gesamter Länge über den Mittelbereich ragend umgeschlagen ist und ein freier Längsrand des Längsrandstreifens mit dem Mittelbereich längs einer Befestigungszone fest verbunden ist, so dass das Verpackungserzeugnis wenigstens einen sich in Bahnrichtung erstreckenden Knautsch-Hohlraum bildet.

A packaging material, a manufacturing method and a packaging tool thereof are provided. Said packaging material comprises an inner structural material (1) and an outer layer material (2), wherein said inner structural material (1) is a hollow material, and said outer layer material (2) is adhered to the outside surface of said inner structural material (1). The inner structural material (1) comprises a middle layer material (22), and, provided on two sides thereof, a surface layer material (21) and an inner layer material (23). Said packaging tool, made from said packaging material, comprises an inner structure (1) formed by folding the inner structural material (1) and an outer layer provided on the outside surface of said inner structure. In this invention, environmentally friendly and renewable hollow materials are used to produce inner structure by folding, and by incorporating an outer layer to produce a packaging tool which is suitable for containing goods.

An automatic coil ejecting mechanism in combination with a dunnage conversion machine capable of producing a strip of dunnage and dispensing the strip of dunnage through an outlet, and a coiling mechanism downstream of the outlet that is capable of rolling a strip of dunnage about a coil axis that is generally horizontal to produce a coiled dunnage product, the coil ejecting mechanism comprising:

a lever arm having a generally vertical pivot axis about which the lever arm is rotatable between a ready position in which the coiled dunnage product is produced by the coiling mechanism and an ejection position in which the coiled dunnage product is ejected from the coiling mechanism, the lever arm being mounted at the pivot axis to a support frame secured to the dunnage conversion machine, and a push plate mounted to the lever arm at a location spaced from the pivot axis, the push plate having a surface that is parallel to a pivot plate that includes the pivot axis, where the pivot plane is perpendicular to the coil axis when the lever arm is in the ready position, and where the push plate is capable of ejecting the coiled dunnage product when the lever arm is in the ejection position.

A system for providing a web of inflated containers includes a conveyance system, a detachment arm, and a controller. The conveyance system has an operative mode in which the web is advanced along a path of travel by counter-rotating members having a nip through which at least a portion of the web passes and (ii) an idle mode. The detachment arm is positioned beside the path of travel downstream from the conveyance system. The detachment arm has a separator end to engage the web in the path of travel. The controller is programmed to operatively control the conveyance system to move to: (i) the operative mode to advance the web by a predetermined number of containers and (ii) the idle mode in which a transverse detachment line of the web is aligned with the separator end of the detachment arm.

A stretchable tubular net (N) is fitted around a columnar support member (6). Then, a distal portion of the net is folded radially outward or inward by a plurality of guide members disposed circumferentially of the net (N), while moving the guide members toward a net proximal side axially relative to the support member (6), whereby the net (N) is rolled up radially outward or inward to form an annular roll portion (C). Then, after the annular roll portion (C) is formed, the annular roll portion (C) is tightened by drawing a portion of the net (N) projecting from the annular roll portion (C) to a proximal side relative to the annular roll portion (C) toward the proximal side while supporting the annular roll portion (C) by keeping a holder in abutment against a proximal side portion of the annular roll portion (C).
