A box style manufactured from a single sheet of corrugated board. The sheet is scored and slotted to permit folding. Flaps are the same size from the edge of the sheet to the flap scorelines. The two outer flaps (normally the lengthwise flaps) are one-half the container’s width so that they meet at the center of the box when the user folds them. Flute direction may be either perpendicular to the length of the sheet (usually for top-opening RSCs) or parallel to the length of the sheet (usually for end-opening RSCs). RSCs are the most common type of corrugated box made today.
