The most common box style. Highly efficient design for many applications. All flaps are of the same length, and the two outer flaps (normally the lengthwise flaps) are one-half of the container's width, so that they meet at the center of the box when closed.

Similar to the RSC but without one set of flaps.

All flaps have the same length. The outer flaps overlap by one inch or more. The box is easily closed, either with adhesives or with staples frequently driven through the overlap area. This style is commonly used when the length of the box is considerably greater than the width, resulting in a long gap between the inner flaps. The sealed overlap helps to keep the outer flaps from pulling apart.

All flaps are the same length (approximately the width of the box). When closed, the outer flaps come within one inch of complete overlap. The style is especially resistant to rough handling. Stacked on its bottom panel, the overlapping flaps provide added cushioning. Stacked on its side, the extra thickness provides added stacking strength.

Inner and outer flaps are cut to different lengths. Both pairs of flaps meet at the center of the box. The style is especially strong because both the top and bottom have double the thickness of corrugated board. The inner flaps, with no gap, provide a level base for the product.

This style can also be made with overlapping outer flaps to provide additional cushioning or stacking strength.

This is a self divided box. It is an RSC but with a pre-glued internal divider.
