A method of making flexible and collapsible bulk bags or liners for bulk bags or containers from individual flat panels of material, or tubes of material folded flat, is disclosed. The bags or liners have one or more sidewalls interconnected by at least a bottom wall and preferably also a top wall generally opposed to the bottom wall. The bags are preferably formed by disposing a pair of inner blanks of material with one on top of the other and then heat sealing along a straight line generally bisecting the blanks and thereafter severing the heat seal along its entire length. Next, a pair of outer blanks of material are disposed adjacent the inner blanks with the inner blanks received between the outer blanks. The outer blanks are each heat sealed about their side edges to an adjacent side edge of an inner blank. Once so formed, the inner blanks form a pair of gusseted panels received between the outer and overlying panels. When expanded, this configuration provides four generally rectilinear sidewalls of the bulk bag. To form the bottom wall of the bulk bag, the outer blanks are heat sealed to the adjacent gusseted, inner blanks along canted lines forming a triangular portion integral with each sidewall. When heat sealed in this manner, a generally rectangular bottom wall, integral with the sidewalls, is formed. A top wall may be formed in a similar manner or separately attached to the bag.
