The Regular Slotted Container (RSC) is the most common box style used for shipping and storage. The two outer flaps of an RSC box meet at the center of the box when folded and are usually closed using tape, or staples. Where the product requires additional protection over the top or bottom, corrugated pads can be placed between the inside flaps.
The Regular Slotted Container with Variable Flaps (RSCVF) style of box is similar to the RSC box, except the outer flaps overlap by an inch or more. The RSCVF style of box is used when the length of the box is considerably greater than the width and results in an excessively long distance between the end flaps. This makes it desirable to overlap the outer flaps to prevent them from spreading apart. The RSCVF box is usually closed with staples through the overlapping flaps.
The Full Overlap Container (FOL) is ideal for boxes with relatively narrow widths. The outer flaps overlap the full width of the box making it especially resistant to rough handling. And, the extra thicknesses of corrugated material on the top and bottom panels provide added stacking strength.
The Half-Slotted Box with Cover (HSC) is frequently used for both shipping and shelf storage, and in applications where the cover must be removed and replaced frequently. The top of the HSC box is a tray style which usually extends less than 2/3 the depth of the bottom (PHSC), but can be made to extend the full depth of the bottom (FHSC) if extra strength is needed.
The Double Cover (DC) is frequently used for tall or heavy products that would be difficult to lower into a box. The product is placed on the bottom cover, and the center is placed over the product. The two interchangeable covers (top and bottom) of the DC box are tray style and usually extend only a few inches down the center body.
