Flexible (single use) sack for transporting goods, such as bulk goods, having a weight of at least 3000 N. It comprises a fabric woven from polypropylene tapes and/or threads and exhibits a mean strip breaking strength of at least 550 N per 50 mm. Sacks with an improved safe working load which can be more readily handled, are obtained by using tapes or threads comprising a matrix of 75-85% B.W. of polypropylene and 25-15% B.W. of polyester, preferably polyethylene terephthalate. The polyester is preferably present in the form of fibrils. |
