A carry-on package bag includes a bag opening and two primary bag sheets opposite to each other. Top edges of the primary bag sheets collectively define the bag opening. Each primary bag sheet includes a first fold line, a first foldable sealing section below the first fold line, and a second foldable sealing section between the first fold line and the top edge. Each first foldable sealing section has at least one first carrying hole. Each second foldable sealing section has at least one second carrying hole symmetric with respect to the first carrying hole about the first fold line. The second foldable sealing sections are foldable along the first fold lines toward the same direction to be overlapping and stacked on the first foldable sealing sections so that the second carrying hole and the first carrying hole correspond to and communicate with each other.

A reinforcement for a bag or a sack is described. The reinforcement has an elongate body with a thinner mid-section than its ends. The reinforcement also has a locking clip slidingly engaged with the second middle portion. It is configured to slide in a direction parallel to the longitudinal axis from a first position, where the locking clip is not aligned with the bag fold line and where the bag and the elongate body are permitted to fold along the bag fold line, to a second position, where the locking clip is substantially aligned with the bag fold line and the body fold line, where the locking clip substantially prevents the bag and the elongate body from folding and substantially maintains the bag in an open position.

A new package for storing bulky goods is disclosed. The package is formed from a bag having a width and depth at its base portion and meeting at a top edge, the top edge having no depth. Due to the top edge having no depth, the width of the material on the top portion of the package extends out further than the width of the material on the base portion. To create a package having streamlined aesthetic that looks nice on a shelf, the excess material in the top portion of the bag is folded into the interior of the bag to form a false side gusset. To allow for such folding the bag, in desirable embodiments, side edges of a first and second web forming the bag angle inward at between about 30 degrees and about 60 degrees at a top portion transition point on the bag.

A kraft sack is disclosed for products to be packed and stored in dust and granule forms such as chemical, food, mine, construction and building industry products. The kraft sack was manufactured to prevent from possible odour transition and humidity creation from and into package inside and outside of dust and granule raw materials, and provides protection thereof in order to maintain physical and chemical features of product against interior and exterior factors, against dusting that could occur during evacuation of air through perforation holes over kraft sacks during process of filling the kraft sack.

Packages having raised portions that provide improvements in displaying graphics, such as images and branding.

Disclosed is a flexible packaging container, in particular a plastic film pouch or bag for bulk goods, comprising a front wall (2) and a rear wall (3) as well as a holding space (15) between said walls (2, 3) for goods to be stored; the walls (2, 3) are made at least in part of a film material; the flexible packaging container further comprising an intermediate space (14) which is formed by an inner ply (4) and is separated from the holding space (15) by said inner ply (4); the holding space (15) can be evacuated into the intermediate space (14) via at least one holding space evacuation hole (7) in the inner ply (4), and the intermediate space (14) can be evacuated out of the packaging container (1) via at least one additional evacuation hole (11) that interrupts a transverse seam; the front wall (2) does not comprise any of the longitudinal seam (12) that seals the packaging container (1) in the peripheral direction; the inner ply (4) is formed by a strip (4) which is located on a side of the front wall (2) facing the intermediate space (14) and which is fastened to the front wall (2) using two longitudinal seams extending between top and bottom transverse seams (5.1, 5.2).

A flat-bottomed bag is formed from a flexible sheet that initially is flat prior to being manipulated to form the bag. The sheet is a laminate of a first web and a second web laminated together by an adhesive layer disposed between the webs. The sheet defines a plurality of serially connected side wall panels collectively defining a vertically extending side wall of the bag, and a plurality of bottom panels respectively connected to the side wall panels at respective fold lines. The bottom panels are folded about the fold lines and are attached together to form a flat bottom wall configured to support the bag in an upright orientation. The adhesive layer is in a partial-coverage pattern that includes adhesive-free regions located along each fold line between each bottom panel and the respective side wall panel connected therewith.

The invention relates to a ventilatable valve bag with a wall material (4) comprising at least one gas-permeable inner layer (6) that is impermeable to a filler material and at least one gas-impermeable outer layer (8) as well as two closing sides (10), a first closing side (10) being formed by closing the valve bag (2) and a second closing side (10) being arranged opposite the first closing side (10). An intermediate space (14) is formed between a part of the inner layer (6) defining an inner space (12) of the bag and the outer layer (8), and at least one ventilation channel (18) leading out of a wall material edge section (16) is arranged on at least one closing side (10) of the valve bag (2), between the inner layer (6) and the outer layer (8) of a wall material region, such that the intermediate space (14) can be ventilated to the surroundings.

A square-bottomed packaging bag (1) of the present invention is a square-bottomed packaging bag formed by bending a one-piece soft packaging material and includes a quadrangular bottom surface (10), a front surface (20) and a rear surface (30) standing from two opposite sides of the bottom surface, and a left side surface (40) and a right side surface (50) connecting the front surface and the rear surface, in which each of the left side surface and the right side surface includes a first region (41, 51) positioned on the front surface side, a second region (42, 52) positioned on the rear surface side, and a side-surface-joining portion (43, 53) joining the first region and the second region.

The invention relates to a valve bag, in particular a cross-bottom valve bag, comprising a first wall and a second wall, which are joined to each other by means of side edges or side folds and by means of bottoms and which delimit a bag interior, comprising a valve, which is arranged in one of the bottoms and via which the bag interior can be filled with a filling material, and comprising venting openings in the first and/or in the second wall for venting the bag interior. At least one channel is provided on the outside of at least one wall, which channel covers the venting openings and is formed at least by two parallel fastening strips and by a cover strip, the cover strip likewise comprising venting openings, and wherein the shortest path between the parallel fastening strips along the cover strip is longer than the shortest path along the at least one wall or the cover strip, and/or the parallel fastening strips consist of stretchable material.
