A gas filling method includes the steps of: intermittently transferring a bag to arrange the bag at a gas blowing processing position; inserting a blowing nozzle into a gas guide path of the bag in the gas blowing processing position; pinching the blowing nozzle arranged in the gas guide path from outside of the bag with a pair of pinching members in the gas blowing processing position; causing the blowing nozzle to eject the gas in such a manner that the gas is sent to the gas accommodation portion in the gas blowing processing position in a state where the blowing nozzle is pinched via the bag by the pair of pinching members; and closing the gas accommodation portion in an airtight manner in the gas blowing processing position in a state where the blowing nozzle is arranged in the gas guide path.

A packaging bag has a bag body formed from a flat web and has a first front wall and a second front wall as well as a stand-up bottom formed in a bottom section by folding and gluing the front walls. The flat web has a varnish coating on an outside of the bag body, wherein the first front wall has an adhesive region free of the varnish coating in the bottom section of the bag body.

A method for manufacturing a sheet material container where the sheet material container includes one or a plurality of sheet members including a main-body forming sheet member that has an outer film layer and an inner film layer which are mutually stacked, a containing region that accommodates contents, and a container body that is configured from the main-body forming sheet member and that surrounds the containing region, and the main-body forming sheet member having a main-body sealing portion, which is an attached region between the outer film layer and the inner film layer, and a non-attached region where the outer film layer and the inner film layer are partially not attached, and further having a filling portion where a filler is enclosed between the layers of the outer film layer and the inner film layer in the non-attached region.

The invention concerns an apparatus for manufacturing of containers from blanks of a cardboard based material, said apparatus comprising: a container body forming unit configured to form a cylindrical container body from a substantially plane blank of a multilayer material comprising at least a supporting cardboard layer and a weldable layer; a welding unit configured to fasten an end closure to the container body, said welding unit comprising an inductive welding energy generator for melting of the weldable layer; and transporting means configured to transport a flow of body blanks to the container body forming unit, to transport a flow of container bodies from the container body forming unit to the welding unit, and to transport a flow of container bodies provided with end closures from the welding unit. The invention is characterized in that the transporting means comprises: a first movable gripping arrangement configured to grip at least two container bodies and move these container bodies simultaneously to the welding unit; and a transferring and positioning arrangement configured to transfer container bodies from the container body forming unit to the first movable gripping arrangement and to position the container bodies in a controlled manner to ensure that the first movable gripping arrangement can grip the at least two container bodies properly, wherein the welding unit is configured to simultaneously fasten an end closure to each of the at least two container bodies. The invention also concerns a method for operating an apparatus of the above type.

Described herein are active pouches for obtaining selected release rates of 1-methylcyclopropene (1-MCP) therefrom. A pouch is a sealed thermoplastic containment or envelope defining an interior volume that is excluded from free exchange with the atmosphere, yet is permeable to both 1-MCP gas and water vapor. The active pouches enclose and contain a clathrate of 1-methylcyclopropene with α-cyclodextrin (1-MCP/CD). The rate of 1-MCP release from an active pouch subjected to a selected set of humidity-mediated disgorgement conditions may be varied by varying the interior volume of the active pouch relative to the amount of 1-MCP/CD contained within the active pouch.

Insulated packaging is provided including an inner substrate and an outer substrate attached to the inner substrate to form an air gap therebetween. An expandable material including expandable microspheres is provided with the expandable material disposed between the inner substrate and the outer substrate. An adhesive material different than the expandable material is disposed between the inner substrate and the outer substrate to attach the inner substrate to the outer substrate. A method for forming the insulated packaging is also provided.

A method for applying a lubricant to a pressure relief valve during the process of applying the pressure relief valve to packaging. The method includes temporarily separating layers of the valve with a vacuum applicator when the lubricant is applied. A pressurized nozzle sprays or atomizes the lubricant into the valve opening. Graphite suspended in liquid silicone is used as the lubricant; it is recirculated in a reservoir to keep the graphite in suspension. Optical sensors check for valves before the entrance to, and after exit from, the vacuum applicator.

A trifold side seamed film produce bag includes a front wall and a back wall, first and second side edges sealed together and a seamless bag bottom. The bag is joined at the side edges to additional bags by a perforation. The bag is corona treated on at least one wall and promotional material is printed on the treated surface. The bags are folded to one third of their height to fit compact bag roll dispensers. The bags are folded in a Z-fold or C-fold configuration. The method includes manufacturing the bags and winding them onto cores or forming the bags into coreless rolls. An apparatus for forming the side seamed bags includes an extruder, a tubing flattener, a perforator, a sealer, a corona treater, a printer and a slitter. The treated, printed bags may be stored on rolls for later slitting into two bag streams and folding into thirds.

The present invention relates to a tubular bag machine for producing tubular bag packaging materials from paper, comprising a draw-off station (2) for drawing off a paper web (10), a roughening station (3) for the continuous roughening of at least one joining region of the paper web (10), a moistening station (4) for moistening at least one joining region of the paper web (10), a forming station (5) for forming a bag tube, and an ultrasonic sealing station (6) for sealing the joining region of the paper web (10).
