ABSTRACT:
A method of manufacturing a bulk bag having a side wall height H of at least about twenty inches (51 cm) and a total circumferential length L of at least about ninety inches (228 cm) comprises fabricating a fabric side wall structure having a height H and a total circumferential length L, and providing a plurality of lift loops each having a first and second leg portion. The legs of each lift loop are aligned at spaced locations around the top of the side wall structure, in positions for ready penetration by the tines of a forklift truck, with both leg portions of each lift loop extending a given distance downwardly from the top edge of the side wall structure. The leg portions of each of the lift loops are stitched to the top of the side wall structure by at least three parallel lines of high-strength thread, preferably by chain stitching or lock stitching. The stitching lines are all sewn in one or at most two passes; they extend horizontally across the lift loop legs to anchor the lift loops securely to the top of the side wall structure. There is no horizontal fold of the top of the side wall structure extending down to the anchor stitching.
