Abstract (en)
[origin: EP0849162A2] The bag is made from a self-sealing material. Preferably the sack comprises a woven cloth (3), each fibre (5,6) in warp and weft directions having a sheath (7,8) of rubber. Up to a critical pressure, the fibres seal against one another, without pores. Above that pressure, pores (13) are formed between the fibres. The cloth may be single or multi-layer.
