This invention relates to a paper bag for bulk material such as cement, gypsum, granular material, animal feed or the like, with a bottom and with an upper part opposite the bottom, wherein bottom and/or upper part are folded and glued by closing up the side parts around side fold lines, in particular in the form of a cross or block bottom, wherein for gluing the side parts at least one gluing or bonding agent activatable after the application is provided, which is applied continuously at least from a side fold line up to at least the opposite side fold line of the side parts.

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.

An insulated bag includes a pair of opposing main panels; and a pair of opposing side panels, each side panel attached to each main panel, the main panels and the side panels defining a bag cavity within the insulated bag; the main panels and the side panels defined in an insulated blank, the insulated blank including a first paper layer; and a paper fiber pad coupled to the first paper layer, the paper fiber pad having paper reinforcement fibers interlocked with about 2% to about 25% by weight of a meltable PE/PP bi-component thermoplastic binder fiber distributed substantially randomly, wherein subjecting the repulpable shipping container to a repulpability test produces greater than 85% fiber yield.

An insulated bag includes a pair of opposing main panels; a pair of opposing side panels, each side panel attached to each main panel, the main panels and the side panels defining a bag cavity within the insulated bag; and a handle assembly, the handle assembly comprising a handle portion attached to a base portion; the main panels and the side panels defined in an insulated blank, the insulated blank comprising an insulation batt, a first sheet, and a second sheet, the insulation batt encapsulated between the first sheet and the second sheet, the first sheet attached in facing engagement with the second sheet to form a border, the border extending around a perimeter of the insulation batt, the base portion of the handle laminated within the border.

The present invention relates to a sack for liquid or pulverulent materials having an areal section (F) composed of a water-soluble polymer, wherein dissolution of the water-soluble polymer gives rise to an opening through which the sack can be emptied, to a sack according to the invention that contains a liquid or pulverulent material, to a method for the emptying thereof and the production thereof, and also to the use of the sack for the packing of liquid or pulverulent materials and to the use of an areal section (F) composed of a water-soluble polymer as part of a sack for liquid or pulverulent materials for the reduction of the release of unpleasant odors and/or harmful substances into the air, especially for the reduction of the release of alveoli-reaching dusts.

In embodiments of the invention, a tamper-evident bag includes multiple side walls, a closed bottom, and an opening defined by a top edge of the multiple side walls. A handle feature is disposed on two side walls. A pressure-sensitive adhesive strip is disposed proximate to the top edge of a first side wall. A perforation line of uniform height is disposed in the multiple side walls above the handle feature and below the pressure-sensitive adhesive strip. Methods for using and manufacturing a reusable tamper-evident bag are also disclosed.

The present invention refers to a bag or sack-like packaging, made of polymer material, idealized for packing, transporting and handling of solid powered and/or bulk materials, and provided with a detachable cover which, besides providing safety and guaranteeing the resistance required for transporting and handling the loaded packaging, also enables the opening of the packaging by detachment of the cover, without making cuts or tears, so that the packaging can be reused.

A plastic film bottom bag has a plastic film front wall that is welded or adhesively joined to side wall sections of adjoining plastic film side walls, and/or a plastic film rear wall that is welded or adhesively joined to the side wall sections of the adjoining plastic film side walls, so as to form a seam or casing seam. Further disclosed is a plastic film bottom bag, in which at least one, in particular both, plastic film side walls are provided with a side fold that comprises a welded or adhesive joint extending from or at a distance from the bag opening edge in the direction of the bag end or up to the bag end. The disclosure further relates to blanks for the plastic film bottom bags described herein and to the use of the plastic film bottom bags described herein, as reusable bags or reusable handbags.
