A first sheet panel is folded along a first fold line, and thereby a first folded part is formed in the first sheet panel. Subsequently, the first folded part is folded back along a second fold line, and thereby a folded-back part is formed in the first sheet panel. A corner cut device cuts a second sheet panel and the folded-back part to form corner cut parts. At this time, the corner cut device prevents the first folded part and a base part of the first sheet panel from being cut.

A resealable front panel enclosure and method of manufacturing the same is provided that includes cutting or punching a tab in an unfolded film material and applying a zipper assembly to the film material. The film material is formed into a resealable enclosure by folding the film material subsequent to applying the zipper assembly to the film material. The tab is disposed on an exterior surface of a first side of the formed resealable enclosure, and the zipper assembly is disposed on an interior surface of the first side of the formed resealable enclosure.

A bagger device is provided. The bagger device can include a bag handler configured to handle packaging material configured to define a bag that has first and second walls enclosing an interior cavity configured to contain an object therein for shipping, the first wall including an expansion material that has an expandable configuration and that is expandable to an expanded configuration for providing padding to the first wall to protect the object contained within the interior cavity. The bagger device can further include an expansion device configured to apply expanding conditions to the packaging material, the expanding conditions configured to cause the expandable material to expand from the expandable configuration to the expanded configuration.

Packaging material is provided. The packaging material can include at least one web layer having a surface that includes first and second regions. When corresponding first regions are overlaid with each other and corresponding second regions are overlaid with each other, the overlaid first and second regions can cooperatively surround a cavity. The packaging material further can include a first sealing material disposed in the first region and configured to seal together the corresponding first regions upon application of first conditions to the first sealing material, and a second sealing material disposed in the second region and configured to seal together the corresponding second regions upon application of second conditions to the second sealing material. The second sealing material can be configured such that the first conditions applied to the second sealing material are insufficient to cause the second sealing material to seal.

A method for manufacturing an intermediate material for a soft packaging container according to the present invention includes: a first overlaying step P1 of laying a second raw film sheet 120 over a first raw film sheet 110; a confining portion forming step P2 of forming a filler confining portion 50 for confining a filler 59, the filler confining portion 50 being constituted by a non-joined region between the first raw film sheet 110 and the second raw sheet 12, by joining a portion of the first raw film sheet 110 and a portion of the second sheet 12 to each other; a folding step P4 of folding the first raw film sheet 110 and the second sheet 12 with the first raw film sheet 110 on an outer side, such that the filler confining portion 50 is present in a state where an inner portion thereof is continuous on two sides that are connected via at least one folding position; an accommodating portion forming step P5 of forming an accommodating portion 60 by joining a plurality of portions including at least one of the first raw film sheet 110 and the second sheet 12; and a cutting step P6 of forming an intermediate material A1 for a soft packaging container by cutting at least the first raw film sheet 110. This configuration makes it possible to more readily and reliably manufacture a soft packaging container that has a filler confining portion in more regions.

Embodiments of a method of printing low volumes of paper bags on a digital printing press are provided. In the method, a plurality of orders are received. Each order includes a particular format relating to a bag size selected from a predetermined number of bag sizes and a graphic to be printed. In the method, the plurality of orders are organized into a plurality of batches. Each batch includes orders of the plurality of orders having a same bag size. A first batch is selected, and the graphic of the orders contained in the first batch is digitally printed on a first roll of paper having dimensions associated with the bag size of the first batch. The first roll of paper is fed through the digital printing press, and the digital printing press prints the graphic of each order contained in the first batch without stopping when transitioning between orders.

A web of first or second material is provided with the spout, and a plastic bag is made from side gusset materials in addition to webs of the first and second materials. An aperture is formed in the web of the first or second panel material, and the spout is inserted into and positioned with the aperture, whenever the webs of the first and second panel materials are fed intermittently. After the webs of the first and second panel materials are superposed on each other, whenever the webs of the first and second panel materials are fed intermittently, the webs of the first and second panel materials are heat sealed with each other in a longitudinal direction thereof by a longitudinal seal device, and the webs of the first and second panel materials are heat sealed with the side gusset materials in a width direction thereof by a cross seal device.

In a printing method, is obtained position information of an invisible region invisible from outside, out of the printing surface of the packaging base material. Then a flushing process in which ink is ejected the ink toward the invisible region from the nozzle based on the position information is performed. Therefore, printing for packaging pouch can be satisfactorily performed on the packaging base material without impairing the design quality of the packaging pouch manufactured by applying the bag making process to the packaging base material.
