ABSTRACT:
A flexible intermediate container has at least one improved lifting loop formed by joining integral extensions of a side wall structures. The extensions are at their upper free ends cut to form at least two flaps which are positioned above or below the extensions on both sides of a folding line or seam, thus forming a lifting loop joint comprising frictional area of overlapping layers of fabric material. Friction therebetween is secured by a frictional agent such 2500 glue or hot-melt and/or by a mechanical device. The lifting loop can be gathered together and surrounded by at least one band or sleeve.
