The covers of the A Box are the same size. The outer covers join in the middle of the box. The distance between the inner flaps depends on the box size proportion. It can be used as a package for many products. If better protection is required on the base of the product, an appropriate piece is placed in the space between the box flaps. This method is especially used to remove the stage difference that occurs in box base where many products are packaged and produced from more than one flute.
