In a method of manufacturing gusseted bulk bag liners, a continuous web of gusseted bulk bag liner material having longitudinally extending fold line is advanced along a predetermined path. Simultaneous cutting and resealing apparatus are engaged with the longitudinally extending fold lines of the length of gusseted bulk bag liner material during the movement thereof. The simultaneous cutting and resealing apparatus are positioned transversely to the direction of movement of the continuous web of gusseted bulk bag liner material in accordance with a predetermined program, thereby forming a gusseted bulk bag liner having a predetermined comprising a sidewall, a top wall, a bottom, an inlet chute and discharge chute.
