ABSTRACT:
A container or bag or sack essentially comprises a tubular fabric, in particular a circular fabric of polyolefines, having a double wall formed by turning in or partially inverting the tubular fabric. In addition, a cut extending downwardly from the folded or turned in edge is provided in the double wall, and the folded or turned in edge thus cut open is gathered or tucked all the way around such that this gathered inner wall-sections of the double wall form a suspension or hanging loop. A suspension loop is thus formed in a relatively simple manner. Practically all the warp threads of the circular fabric unite in the suspension loop, imparting to the sack possessing a load-carrying strength at least equivalent to the tensile strength of the fabric. The lifting strength of the suspension loop is considerably increased by the gathering.
