U-Panel bag
U-Panel
bags are constructed with three main body components – one that runs the full
length of the bag forming the bottom and two sides (the “U”) and two additional
pieces of fabric sewn between the U on two sides (the “Panel”). Generally,
U-panel bags will maintain a square shape when filled, especially with the
addition of internal baffles. U-panel bags are an industry standard and the
most popular type of construction.
