<p>A re-usable sack consists of an outer sack (1) and at least one impermeable inner sack (9) with an extra length (10) in relation to the outer sack. The inner sack is fastened to the outer sack by sewing, gluing or welding (5) so that the sack has an open end (3) before filling of the goods. The extra length (10) is placed opposite to the open end of the sack and is turned back, folded or rolled together inside the outer sack. After filling with goods the reuseable sack is closed and made impermeable. The sack is opened at the opposite end (4) to the inlet opening, whereby the extra length (10) of the inner sack is released. <IMAGE></p> |
