Abstract: A packaging for an additive to be added to a plastic batch consists of a packaging film of thermomelting plastic material shaped to form a bag and a thermomelting polyolefin-based adhesive applied to the plastic film and forming closure seams for sealing the bag. The adhesive is moisture crosslinking and can be a hot melt. The thermomelting plastic material is identical to or compatible with a plastic material of the plastic batch to which the packaging and the additive are to be added.

Abstract: A bag for transporting moisture-sensitive goods has a bag wall made of a unilayer multi-ply laminate. The laminate has an outer ply of crepe paper, a central ply made of a barrier material forming a vapor barrier, and an inner ply of weldable thermoplastic plastic material. The bag wall also has bonding agent plies between the outer ply and the central ply and between the central ply and the inner ply.

Abstract: A profiled bottom bag made of paper, plastic foil or a similar foldable material has at least one profiled end provided at its outside with a handle-forming strip whose length is essentially that of the profiled end. A handle section extends between connecting areas and, in contrast to the connecting areas, is narrower. The handle-forming strip forms part of a prefabricated cut section encompassing a separating strip which extends under the handle section of the handle-forming strip without being bonded thereto, whose width corresponds to that of the handle-forming strip in the end-connecting areas of the strip, whose length, measured in the longitudinal direction of the profiled end, but in contrast to the length of the handle-forming strip, is shorter up to the narrow connecting areas on both sides of the handle section of the handle-forming strip. The separating strip and the handle-forming strip are bonded together.
