SLOTTED BOXES: International Fibreboard Case Code: 02 Series

Slotted box styles are generally made from one piece of corrugated or solid fiberboard. The blank is scored and slotted to permit folding. The box manufacturer forms a joint at the point where one side panel and one end panel are brought together. Boxes are then shipped flat to the user. When the box is needed, the box user squares up the box, inserts product and closes the flaps. The International Fibreboard Case Code refers to these styles as Slotted-Type Boxes, while the carrier classifications call them Conventional Slotted Boxes.

0200 Half Slotted Container (HSC)
Same as Regular Slotted Container (0201) without one set of flaps.
 

0201 Regular Slotted Container (RSC)
All flaps have the same length, and 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 folded. If the product requires a flat, even bottom surface, or the protection of two full layers, a fill-in pad can be placed between the two inner flaps.

This is a highly efficient design for many applications. There is very little manufacturing waste.

The RSC can be used for most products and is the most common box style.

     

0202 Overlap Slotted Container (OSC)
All flaps have the same length. The outer flaps overlap by one inch or more.

The box is easily closed, usually with staples driven through the overlap area.

This style is 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.

 

0203 Full Overlap Slotted Container (FOL)
All flaps have the same length (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.

     

0204 Center Special Slotted Container (CSSC)
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.

A variation of this box is the Side Special Slotted Container-SSS. All pairs of flaps meet, but not at the center of the box.

 

0205 Center Special Overlap
Slotted Container (CSO)

All flaps have the same length (one-half the length of the box). The length of the box can be no more than twice its width.

When closed, the inner flaps meet at the center of the box, providing a level base and full top protection. Depending on the ratio of length to width, the outer flaps overlap at random, up to full overlap.
