A baffle bag is a tubular or 4-Panel bag that has pieces of fabric or other material sewn across each corner to enhance the bag's appearance, load stability, squareness, and capacity to make better use of storage or transportation space. A typical bulk bag without baffles may sag or bulge at the sides when filled. The stability and stackability of baffled bags make them perfect. They also increase the amount of storage overall. Four-panel baffled bags are the most popular kind of baffled bag.
