A method for sealing and cutting of a flexible material for forming a flexible container comprising a product volume and at least one structural support volume can include feeding at least two flexible material into a sealing apparatus comprising a sealing surface and an opposed anvil surface; contacting a seam region of the at least two flexible material with the sealing surface to form a seal in the seam region and cut the seal to form a seam in a single unit operation. The seal defines one or both of at least a portion of a boundary of the product volume and at least a portion of a boundary of the at least one structural support volume.

An accordion-sides square-bottom bag and manufacturing method thereof, comprising a paper tube (10) made by a sheet enclosing the sides; accordion sides are folded on two sides of the paper tube (10); the paper tube is provided with a first indentation line (21) and a second indentation line (22), the distance from the second indentation line (22) to the base being greater than the distance between the first indentation line and the second indentation line, but not exceeding twice the distance; two ends of the second indentation line (22) are symmetrically provided with a first crease line (31) and a second crease line (32), the distances between the respective ends of the first and second crease lines and the two edges of the paper tube (10) exceeding the folded depth of the accordion sides; and a first cutting line (41) and a second cutting line (42) are provided from the ends of the first and second crease lines to the base of the paper tube (10). The accordion-sides square-bottom bag enlarges the area of the glued surface of the bottom of the bag, such that the material on the bottom is uniformly distributed, and the bottom is adhered firmly, thus reducing the maximum thickness of the bottom, and reducing the footprint of packaged material during transportation.

The present invention relates to a container having consumer friendly sides. The container has a front panel and a back panel, each having an exterior surface. A side sealed portion of the container is folded over and secured to the exterior surface of container. The side sealed portion having at least one angled portion. Securing the side sealed portion to the exterior surface of the container forms a smooth side with the portion of the container that is folded over, or flexed, to allow the side sealed portion to be secured to the front or back panel. A method for forming the container assembly, and a machine for manufacturing the container assembly are also disclosed.

A package made of fibre material has at least a first wall and a second wall, as well as an adhesive stripe between the first wall and the second wall. The adhesive stripe constitutes a seam closing the package on that side of the package where the package is arranged to be opened. The paper package further has at least one fibre rip stopper at the edge of the adhesive stripe or at a distance from it in the direction of the interior of the package, the stopper being arranged to delimit the point separating the first wall and the second wall to the edge of the adhesive stripe or to a distance from it in the direction of the interior of the package when the package is opened. The disclosed embodiments also relates to a method for making a package of fibre material.

A flexible, stackable, recloseable container for storing a quantity of products comprising a plurality of walls defined by a first sheet and a second sheet attached to at least a portion of the first sheet. The second sheet extends over at least three of the walls. The opposing container walls each have a sealed portion and one or more tucks, the tucks comprising a portion of the first sheet tucked toward the interior volume. A portion of the second sheet defines a recloseable feature located over an opening for reclosing the container. The second sheet includes a line of reduced strength at or adjacent at least a boundary adjacent the tucks and disposed between the opposing container walls each having the sealed portion and an adjacent container wall. The second sheet can include a hinge about which the recloseable feature pivots from closed position to open position.

A packaging unit for hygiene articles, the unit being formed from a sheet of material having an inner surface, said inner surface comprising an edge portion being provided with a resealable adhesive for closure of the packaging unit. The sheet has a longitudinal center line and at least one transversely extending folding axis dividing the sheet into a first region and a second region. A tab is arranged at an edge portion of the first region. The tab extends in a longitudinal direction from said edge portion so that an extension of the tab along or parallel to the center line from a tab base to an outer edge of the tab is 0.5 cm or more. A method of forming the packaging unit is also provided.

A first body of fastener material is joined to a first web of panel material while a second body of fastener material is joined to a second web of panel material. The first and second bodies of fastener material are interposed between the first and second webs of panel material and aligned with each other after the first and second webs of panel material are superposed with each other. A third body of fastener material is joined to a web of side gusset material to be interposed between the first and second bodies of fastener material after the first and second webs of panel material are superposed with each other, the first and second bodies of fastener material being aligned with the third body of fastener material.
