Box Styles and Definitions

Box Styles There are many box styles that will meet most every packaging need. The most often used box styles are shown below. Don’t see what your looking for? Please contact our customer service staff, we look forward to assisting you with all of your packaging requirements.


Regular Slotted Container (RSC) The RSC is the most common box style, and can be used for most products. All flaps are one half of the containers width, so the outer flaps (normally the lengthwise flaps) meet at the center of the box when folded. This highly efficient design with very little manufacturing waste is your most cost effective container.


Full Overlap Container (FOL) When closed, the outer flaps come within one inch of complete overlap. This makes the FOL box style especially resistant to rough handling. In addition, the overlapping flaps provide extra cushioning when stacked on its bottom panel and added stacking strength when stacked on its side panels.


Half Slotted Container (HSC) The HSC is used when an open top box is needed. In addition, when a box with a cover that must be removed and replaced frequently is desired the HSC is used.

One Piece Folder (OPF) The one piece folder is a flat piece of corrugated that is creased so the flaps, when folded up, form the sided, ends and top of the container. This style is frequently used for shipping literature.
