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.

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 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.

A method of delivering goods, the method comprising the steps of: providing a collapsible carrier bag (20), or providing a collapsible transport container (20), wherein the carrier bag (20) or the transport container (20) is provided in a collapsed state (20A); expanding the collapsible carrier bag or transport container in an environment having a pre-determined condition of the environment; loading chilled or frozen goods into an interior storage space of said transport container or carrier bag; and transporting said loaded transport container (20, 20C) or carrier bag (20, 20C) to a destination (DD).

A collapsible bag is disclosed having a handle and a compartment attached to the handle, the compartment formed of nine panels comprising front and back trapezoidal panels, a rectangular bottom panel, and left and right triangular expansion zones, each triangular expansion zone formed by an isosceles lower triangular panel and first and second congruent, scalene triangles. The expansion zones occur below a midpoint of the height of the compartment and distributes more space near the bottom of the bag while narrowing the bag at the top of the compartment. Moreover, the distance between the top of the isosceles triangular panels when the bag is open is greater than a width of the rectangular bottom panel and less than the handle width.
