A folder system with an accordion spine 16, and a method of making same is disclosed. The folder may have a plurality of insert elements 52, 60 either at manufacture or by a stub system which are bound into the spine at the valleys 32 of the web which forms the spine. The web is made of outer zig-zag web 40, with the inner web 42, 44, 46 joining adjacent insert elements and the outer web, to create a strong spine of web and inserts.

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.

A flexible package having a closure device and a lap or fin seal is provided that reduces or eliminates an air gap present at the fin or lap seal portion of packages. The package can include a film with a closure applied to the film. The flexible package can include a film having a closure device applied to the film transverse to the first and second side edges of the film, with the first side edge portion extending into the fin seal such that at least a portion of the first side edge portion eliminates an air gap between the fin or lap seal and at least one of the first and second side edge portions.

The invention relates to a method for producing a bag, in which method a bag is produced from a fiber material, preferably a paper material, wherein a web made of the fiber material, preferably a paper web, is unwound as a flat web, thereafter sequential adhesive strips are applied in continuous operation, thereafter the flat web is folded to form a bag shape, thereafter the adhesive strips are activated, for connection, by the application of heat, and thereafter individual bags are cut from the flat web by means of a cutting device.

A method and apparatus for making bags or pouches is disclosed. It includes a track, at least two sleds that move on the track, and operating stations mounted on the sleds. The film moves along the track, and the sleds move with the film while performing operations on the film. The system can have the sleds stationary while operating for an intermittent machine, and move to reconfigure when the film is moving. The operating stations include one or more of a sealer, a heater, a cooler, an inserter, a knife, a punch, a perforator, a static charger, and a printer. The track forms a continuous path or is linear. A controller controls the sleds and operating stations. The controller includes an operating time and/or a reconfiguration module. The operating time module is responsive to a user set material thickness or a sensed material thickness.

A flexible pouch and a method for making a flexible pouch is provided. The pouch includes a pouch body defined by a peripheral edge. A dividing seal is disposed between opposite ends of the flexible pouch so as to define two pouch spaces. The pouch includes two fitments are mounted to a respective pouch space. One of the fitments is configured to support the pouch body in an upright manner. A method for making said flexible includes forming a flexible pouch having an open top. A dividing seal extends from the open top to the bottom of the pouch so as to define two pouch openings and two pouch spaces. Substances are introduced into the pouch spaces by a first nozzle and a second nozzle inserted into a respective first space and second space and filling the pouch body through the first and second nozzle.

A method and apparatus for sealing a bag made of a polymeric material by applying heat activated layers on different portions of the bag, wherein the first adhesive layer and the second adhesive layer have respective heat activation temperatures below the softening point temperature of the polymeric material; after creasing the bag along a fold line, applying heat at a temperature below the softening point temperature of the polymeric material to activate the first adhesive layer and the second adhesive layer to adhesive states after the bag has been filled with contents; and folding the bag to form an adhesive-to adhesive seal by contact between the heat activated first adhesive layer and the heat activated second adhesive layer.

A woven plastic bag is made by longitudinally feeding flat-lying fabric web having a layer of woven-together plastic strips on a first face, opposite longitudinal edge regions spaced transversely from each other and each extending over about 10% of a transverse width of the fabric web, and a middle section between the longitudinal edge regions. A pattern is applied the first face of the fabric web in a pattern that repeats along the production direction only locally with a coating in the form of a film or in the form of a liquid plastic of a width or shape that varies transversely, and the fabric web is shaped into a fabric tube. In order to form individual woven plastic bags, the fabric tube is cut transversely into pieces of the fabric tube suitable for subsequent filling and sealing.

The invention relates to a flat-lying side-gusset bag made of a plastic fabric composite (2) and to a method for the production thereof. The side-gusset bag has opposing front walls (3a, 3b), side gussets (4a, 4b) introduced in between said front walls (3a, 3b), and folding edges (5) between the front walls (3a, 3b) and the side gussets (4a, 4b). Peripheral sections of the plastic fabric composite (2) are connected together in an overlapping region (10) at a longitudinal seam, wherein the plastic fabric composite (2) has a plastic fabric (7) and at least one closed plastic layer. The side gussets (5) extend, in the case of the flat-lying side-gusset bag, in each case over at most ⅓ of the width of the front walls. According to the invention, the overlapping region (10) is arranged off-center on one of the front walls (3a, 3b) at least partially over one of the side gussets (4a, 4b) or at one of the side gussets (4a, 4b). In order to be able to form such a side-gusset bag, in the production method, first of all a closed, two-layer tube (12) is formed, from which a side-gusset tube (1) is subsequently formed.
