All flaps are the same depth, and the two outer flaps (normally the lengthwise flaps) are one-half the container’s width, so that they meet at the enter of the box when folded. This is highly efficient design. The only overflaps are the flap for a glued or stitched manufacture’s joint, and the inner (or minor) flaps. There is a very little manufacturing waste. The RSC can be used for most products, and is the most common box style. If the product requires a flat, even bottom surface, or the protection of two full layers, a fill-in pad can be placed between the two inner flaps.
