The Regular Slotted Carton (RSC) is the most widely used box design in packaging. Its straightforward and efficient structure makes it ideal for a variety of shipping, storage, and handling needs. In this design, all four flaps are uniform in length, with the two outer (usually lengthwise) flaps sized at half the box’s width. When folded, these flaps neatly meet at the center, providing a secure and practical closure for the carton.
