A flexible container is formed of a single piece of material and includes a bottom, a top and side walls, with two opposite openings in top portions of the side walls below the top. The material of the top is folded or gathered from the opposite openings toward the center of the top, thereby forming an integral lifting loop formed of integral extensions of the side walls. The lifting loop extends over the center of the container between the opposite openings. The thus folded or gathered material is joined at an uppermost lifting area of the lifting loop, thereby forming a permanent lifting handle.
