A stitchless baffle bulk bag including one or more baffle inserts that are heat sealed to a bag body using a hot melt film. A baffle insert includes a plurality of lateral straps spaced in between longitudinal panels. Tabs extend from the longitudinal panels into the space between lateral straps, above and below the lateral straps. The hot melt film is applied to at least a portion of the longitudinal panel and to the tabs, which is then heat sealed to the body under heat and pressure of heat seal bars. A hot melt sealed tab on both sides of the strap extending beyond the pivot point of the strap counters the forces of peel encountered by the strap and/or by a heat sealed joint of the tab or longitudinal panel
