Radiological containment bags for use in storing alpha particle emitting waste are described. The radiological containment bags are formed of a multilayer film with an inner layer of the film being a sacrificial layer that lies between the interior of the bag and a structural polymeric layer. The sacrificial layer includes a flexible composite material that in turn includes a polymeric matrix and an alpha particle energy absorber incorporated in the polymeric matrix. The sacrificial layer can include a chromophore that can detect early degradation of the sacrificial material.

A paper sack for bulk material such as cement, gypsum, granulate, animal feed or similar, having a base, preferably a cross bottom or block bottom, and having an upper part which is disposed opposite the base and in which a valve tube is optionally arranged for filling the paper sack, wherein the paper sack has at least one paper layer having an overlap which is sealingly adhesively bonded toward the sack interior; and wherein the layer of the paper layer facing the sack interior has an air-permeable region in the region of the overlap which is covered by the layer of the paper layer facing the sack exterior. The at least one paper layer at least regionally has a water-repellent/water-tight coating facing the sack exterior.

A bag includes a body with a closed and stepped end, and an opening in the closed end as a handle. A tube having a first panel, a second panel and two side gussets is provided. The tube is foldable inward along a longitudinal fold line on each of the two side gussets. A stepped end is formed. The first panel has a first longitudinal length, the two side gussets have at least one portion having a second longitudinal length, which is longer than the first longitudinal length and shorter than a length of the second panel. The second panel of the tube is folded along a latitudinal fold line between the top line of the first panel and the top line of the tube so as to form the closed end. The opening is cut in the closed end.

A delivery pouch, in particular for perishable goods, includes a front wall comprising an inner layer having opposing first and second side edges and an outer layer having opposing first and second side edges that are connected to each other. The inner layer of the front wall of the pouch comprises a foamed polymer layer and the outer layer of the front wall of the pouch comprises a foamed or non-foamed polymer layer. The rear wall of the pouch comprises, at least in that section of the rear wall of the pouch that does not protrude over the front wall of the pouch, an inner layer having opposing first and second side edges and an outer layer having opposing first and second side edges that are connected to each other. The inner layer of the rear wall of the pouch comprises a foamed polymer layer and the outer layer of the rear wall of the pouch comprises a foamed or non-foamed polymer layer. The front wall of the pouch or the rear wall of the pouch comprises at least one fastening component on the upper end of the pouch, wherein the fastening component is designed to close the closable opening on the upper end of the pouch after the protruding section of the rear wall of the pouch is folded over the front wall of the pouch. Also disclosed is a delivery box comprising a delivery container and a lid and containing a multitude of delivery pouches, and a method of transporting goods for delivery, in particular for perishable goods, by use of the delivery pouches or by use of the delivery box described herein.

Methods of opening and adding expansion materials to containers made from flexible materials. The methods involve forming a partially completed container blank that may have four layers of flexible materials. The partially completed container blank may be opened by separating a portion of the first layer from a portion of the second layer by bending portions of the second, third, and fourth layers toward a first direction; and dosing the partially completed container blank, by adding an expansion material out of a dispenser and into a space disposed between a portion of the first layer and a portion of the second layer.

A container includes a pair of opposing side panels; and a pair of opposing main panels, each side panel of the pair of opposing side panels attached to each main panel of the pair of opposing main panels, the pair of opposing main panels and the pair of opposing side panels together at least partially defining a cavity within the container; wherein the pair of opposing side panels and the pair of opposing main panels are defined by a blank, the blank including a base layer and a film, the film coupled to the base layer, the film positioned facing the cavity, the film defining the cavity.

A flexible package for storing and transporting bulk goods. Such flexible package can have material-impermeable connections for spreading out sections of the flexible package wall so as to correspond to a predefined shape. One or more docking connections for filling and discharging can be included. The flexible package can have a square bottom and adjacent to the sides thereof triangular stubs as lateral walls. Together, such lateral walls can form an upwardly open pyramid shape. Opposite the bottom, a coupling element can be connected in such a manner that it presents the flexible package so as to be sealable in a standardized manner on open-sided ends of the lateral walls.

A collapsible bag or pouch for collecting samples of soil, mud, liquid and gases, having an internal mechanical seal and a heat sealable area near the opening that is protected during sample loading, preferably by a funnel detachable from the pouch. After loading and prior to heat sealing the pouch is secured from the outside by mechanical interlocking seal. The bag also has an air-tight port for sampling the gaseous headspace after the bag is sealed.

The present invention relates to a paper sack for bulk material such as cement, gypsum, granulate, animal feed or similar, having a base, preferably a cross bottom or block bottom, and having an upper part which is disposed opposite the base and in which a valve hose is optionally arranged for filling the paper sack, wherein the paper sack has a coated paper layer, having a gas-tight coating facing the sack interior, wherein the coating forms the surface of the inner wall of the paper sack contacting the filling material, and wherein the coated paper layer has an overlap which is sealingly adhesively bonded toward the sack interior, and wherein the layer of the coated paper layer facing the sack interior has perforations in the region of the overlap which are covered by the layer of the coated paper layer facing the sack exterior.

A non-continuously laminated structure of thermoplastic films comprises thermoplastic films with differing material compositions and differing functional benefits. In particular, one or more embodiments comprise thermoplastic films that are co-extruded separately and then combined together by a post-extrusion bonding process. The differing composition of the various films of the non-continuously laminated structure of thermoplastic films and the post-extrusion bonding process, provide the structures with the functional benefits of the individual films.
