A soft container for bulk and piece materials has inner and outer shells and the shape of the surface of outer shell in straightened state is formed by two surfaces located in parallel horizontal planes, which are connected at a right angle to a vertical flat surface. Thus, these surfaces of outer shell located in parallel horizontal planes are formed by lower and upper walls, which have the same shape and dimensions, while the central portion of said upper wall of the outer shell has through holes, whose edges are connected with a cylindrical loading sleeve, moreover, said outer shell with a loading sleeve is made of a woven material based on polypropylene or polyamide. The aforementioned upper and lower walls have a rectangular shape with a side length from to . The outer surfaces of upper and lower walls are spaced from to from each other and the ends of each strapping loop are sewn to the outer shell, spaced from each other and located on different adjacent faces of a rectangular parallelepiped, whose shape is formed by outer shell in straightened state. |
