Abstract: A bag for bulk material made of paper and/or other sheet material, having at least one bottom formed in a cross bottom or block bottom folding manner, the bottom fold having two side flaps which are folded about side fold lines extending in the longitudinal direction of the bottom to form the bottom, the side flaps forming an overlap in the closed state, the width of the overlap being a maximum of 10 millimeters, preferably a maximum of 6 millimeters and further preferably a maximum of 4 millimeters.

Abstract: 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.

Abstract: The invention relates to a paper bag for packaging of bulk material, having a standing bottom (2) and a valve bottom (3), a front wall (4) and a rear wall, the front wall and the rear wall being glued to each other in overlapping relationship, the paper bag further comprising cover sheets (5, 5?) for closing the standing bottom (2) and the valve bottom (3), wherein the cover sheet (5) of the standing bottom (2) and/or of the valve bottom (3) is provided with a tear open strip (6) which extends across the entire length of the bottom. It is characterized in that a foil (9) is placed below the standing bottom cover sheet (5) and/or below the valve bottom cover sheet (5?) and is removably glued to the paper bag (1) in such a manner that after tearing open of the standing bottom cover sheet (5) and/or of the valve bottom cover sheet (5?) the foil (9) still closes the paper bag (1) completely and sets the product free only after peeling off said foil.
