A method for manufacturing a pouch-type packaging material includes: a first folding process; a first cutting process of cutting the top-side sheet material, a second sub-region, a first main region, and a first sub-region along a first cutting line that extends from a portion where the top-side sheet material and the second sub-region overlap to a portion closer toward a bottom side in a z direction beyond a first boundary line; a second folding process; a second cutting process of cutting the top-side sheet material, the first sub-region, the first main region, and a second main region along a second cutting line to form a top-side sheet from the top-side sheet material, where the second cutting line extends from a portion where the top-side sheet material and the first sub-region overlap to a portion closer toward the bottom side in the z direction beyond the second boundary line.

A tab system for a folder (10a), and a method of making same is disclosed. The tab is enlarged to carry more information/indicia. The visual indicia space (16a), i.e. the viewable space on the front (32a, 36a) of the folder which allows viewing of the enlarged tab is achieve without violating the overall size restrictions (40a) of the file folder. Instead, the front of the folder adjacent to the tab on the back panel, is cut away (32a,34a) to expose a greater portion of the back panel (14a) and allow an increase in visual indicia space. The remaining portion of the front panel, not adjacent to the tab may also be cut away (34a) to allow other enlarged tab files, with offset tabs, (22d, 21a) to be viewable behind the present file.

A woven laminated plastic bag having an easy open feature is provided. The easy open feature is generally defined by a weakened portion in the bag. In various aspects the bag can be fabricated from a woven polyethylene layer which can be laminated with a polyethylene film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.

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 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.

An apparatus and method for producing microperforated patches for MAP includes drilling or punching microperforations through continuously advancing label stock. Holes can be drilled by at least one microperforating laser traversed across the label stock as it advances, a laser beam deflected or split using a servo-driven galvanometer, beam splitters, or a plurality of mirrors, or by drills mounted into a rotating die cylinder across which the stock passes as it is advanced. Numbers and sizes of microperforations can be adjusted by manipulation of laser control parameters, or by exchange of die cylinders. The laser can be a CO2 laser with between 10 W and 100 W output. The drills can be carbide drills. The label stock is typically 6-18 inches wide, and can include an adhesive covered by a release sheet. The stock to be microperforated can include separate rows of labels or can be suitable for die-cutting after microperforation.

A web material made of a woven fabric is divided into web sections by tear lines. The tear lines weaken the web material without causing a complete separation of the web sections from the web material. The web sections are separable from the web material by being torn off along the tear lines. Cuts are formed in the woven fabric along transverse sections of each tear line, the transverse sections running essentially transversely to the longitudinal extension of the web material, which cuts are spaced apart from each other and are oriented in the longitudinal direction of the web material or transversely to the transverse section of the tear line, with the cuts being connected to only one transverse section of the tear line.

The product efficiency of bags each with an end face part is increased. A panel webs is guided to be divided along a line of weakness of the panel web and to be folded along division edges of the panel web. This guiding of the first panel and temporary sealed sections cause a side gusset to be cut open along a line of weakness of the side gusset such that open surfaces are formed. After the forming of the open surfaces, an end face web is supplied to be superposed on folded parts of the panel web and the open surfaces of the side gusset.
