ABSTRACT:
A flexible container is formed from a hose-like blank having two diametrically opposite longitudinal slots or holes and at least one intermediate slot or hole. One half of the hose-like blank is inserted through the intermediate slot in such way that one inner sack, one outer sack and at least one integral lifting loop defined by material areas are formed. Two material areas are formed by material sections between the opposite slots and the intermediate slot extending from the outer sack directly into the inner sack. A third material area is formed by a material section between the opposite slots and extending from the outer sack between the first two material area and into the inner sack.
