Mineral powder packaging bag

The invention relates to a mineral powder packaging bag particularly. The mineral powder packaging bag comprises a bag body and a bag mouth. The bag body is weaved integrally by a water-proof damp-proof layer, a kraft paper layer and a leakage-proof layer from outside to inside. The bottom face of the bag body ( under seal) and the side face of the bag body are in sealing connection in an arc shape, the longitudinal section of the bag body is in an ellipsis shape, multiple arc-shaped vertical strengthening bands parallel with the bag mouth are arranged on the outer layer of the bag body, and the spaces of each two adjacent arc-shaped vertical strengthening bands are equal. The mineral powder packaging bag has the advantages that the kraft paper layer with certain fastness intensity are arranged in the materials of the bag body due to the fact that texture of the mineral powder materials is heavy, and strong fastness performance of the packaging bag is guaranteed after being filled with mineral powder materials through the additional arrangement of the vertical strengthening bands and horizontal strengthening bands which are arranged criss-crossly on the outer layer of the bag body, so that the sealing effect of the packaging bag is achieved, and mineral powder materials are prevented form drifting away during the transportation process.
