<p>A flexible bulk container for carrying up to one tonne or more of material in e.g. granular form. The container is of woven fabric, e.g. polypropylene, and includes a bag portion (1) to which are attached lifting loops (2). Reinforcement is provided in the region of attachment of the loops (2).</p><p>To provide a simple and effective manner of obtaining reinforcement, in regions (11, 12) the strength of the fabric warp per unit width is increased, e.g. by using higher tenacity warp threads and/or by cramming the warp threads closer together. Lifting stresses from loops (2) are transmitted down the higher warp strength regions (11,12). The regions (11,12) could be adjacent a seam (7) between two fabric portions (3, 4), extending along the selvedges. In an alternative arrangement, the container has a tubular main body portion, higher warp strength regions being disposed around the periphery.</p> |
