The present invention relates to an air bag machine. The operational steps of the machine mainly includes: first, placing bag film on a main body, and extending one end of the bag film to pass through a sealing device and material pulling module in sequence. Subsequently, the bag film is pulled to the rear end by the material pulling module when air filling is carried out to the bag film, and at the same time, the bag film is cut to form a hole entrance by a cutting element so as to facilitate filling air into the bag film Thereafter, the sealing device is used to seal the hole entrance to complete the sealing of the finished bag film.

A machine for providing cushioning products of varying lengths from a supply of a web material having sequential transverse rows of inflated protrusions. A pair of opposing feed members form a feed nip for moving the web along a path of travel. At least one sensor detects location information for the sequential rows of inflated protrusions as the web travels along the path of travel. A severing device is moveable between (i) an engaged position to separate the web transversely or perforate the web transversely and (ii) a disengaged position. A controller is programmed (i) to receive the location information and (ii) to operatively control the severing device to move it to the engaged position when a selected row is in a determined position relative the severing device.

An inflating stick and a processing machine are provided. The inflating stick includes a body, a link rod, a cutter, and one or more inflating tubes. A front end of the body includes a guiding segment with a cone structure. A rear end of the body includes a packing segment. The body includes a gas inlet formed on the packing segment, an internal chamber allowing gas to flow into through the gas inlet, and gas outlets formed on an outer wall of the body allowing gas to flow out. The packing segment includes a first locking structure and a second locking structure. The first locking structure and the second locking structure communicate with the gas inlet. The second locking structure is detachably fastened to the first locking structure. The link rod and the cutter are disposed in rear of the body. The inflating tube is connected to the gas inlet.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

A fibre-containing sheet comprising a folding pattern and a partly or fully folded sheet product obtained from the fibre-containing sheet is disclosed. The folding pattern of the fibre-containing sheet comprises a series of parallel straight fold lines and a series of zigzag fold lines. Each zigzag fold line has a breadth which is greater than a breadth of a straight fold line. The partly folded sheet product can be shaped into various complex geometrical shapes, including spheres and saddle points, as a result of the folding pattern. A method for producing the fibre-containing sheet as well as use of the fibre-containing sheet is also disclosed.

An airbag and a method for inflating the airbag using an inflation system. The airbag includes a packaging body. The packaging body includes a front wall, the front wall has a top edge; a rear wall, the rear wall has a top edge, wherein the top edge of the front wall and the top edge of the rear wall forms an opening for receiving an article; a first adhesive liner coupled to an inner surface of the rear wall, the first adhesive liner positioned adjacent to the top edge of the rear wall, the first adhesive liner runs along and parallel to the top edge of the rear wall; a second adhesive liner coupled to the inner surface of the rear wall, the second adhesive liner adjacent to the first adhesive liner, the second adhesive liner runs along and parallel to the first adhesive liner, wherein the first adhesive liner and the second adhesive liner comprises a permanent adhesive; and a line of weakness in the rear wall runs parallel to the first adhesive liner and between the first adhesive liner and the second adhesive liner.

A web, method, and apparatus for forming dunnage units. The web includes first and second elongated layers. A plurality of seals that hermetically join the first elongated layer to the second elongated layer to form a plurality of inflatable pouches and an inflation channel that is in fluid communication with pouches and is disposed outside of the pouches. An inflation side line of perforations, a gap forming area, and an opposite side line of perforations are arranged in a line between pair(s) of the pouches.

The present invention discloses a method of producing at least a pair of interlocking adjacent layers of a paper packaging product, the pair of interlocking adjacent layers being formed of a sheet of slit paper having a slit pattern, the slit pattern upon expansion, forming cells that include land regions that are inclined with respect to a plane of an unexpanded sheet. The method comprises slitting the sheet of slit paper with beveled blades that have a first wedge angle on one side of the blades and a second wedge angle on the other side of the blades, wherein the first wedge angle is wider than the second wedge angle to produce slits that upon expansion, produce the lands regions that have angles of inclination in a range for 50 to 85 degrees.
