Overlap Slotted Container (OSC)
The OSC is similar to the RSC except the outer flaps overlap a specified amount but not less than 1 inch. The inner flaps do not meet.
Full Overlap Slotted (FOL)
The FOL is similar to the RSC excep the major flaps fully overlap. All the flaps have the same length, the width of the box. When closed the outer flaps will fully overlap each other. With the overlapping flaps this style offers more cushioning on the top & bottom. When stacked on its side the extra thickness provides extra stacking strength.
