Regular Slotted Container

The Regular Slotted Container (RSC) is a widely used shipping box due to its standard design, making it a popular choice for automatic manufacturing. It has flaps of equal length from the score to the edge, with the significant flaps meeting in the middle. The minor flaps do not meet except when the length and width are equal. This design saves materials without compromising the box's functionality.

Manufacturers typically use adhesive to join the joints but may also use tape or stitching. The box is then shipped flat or knocked down to the packager, who sets it up, fills it, and closes it for shipment. Box closure may be done using tape, adhesive, or staples.

The material used for the box can be double-wall or three-wall corrugated cardboard, with the most commonly used materials being B-flute, EB-flute, and EE-flute. E-flute is also an option for small boxes that need to hold lightweight items. The box is designed to contain the product from manufacturing through distribution to sale and sometimes end-use, making it ideal for easy transporting and stacking.

The size of the container can be customized, and it can also be made with custom printing to pursue aesthetic appeal and branding. It has many uses, particularly for shipping, organization, and storage, and it can be designed for particular purposes, such as shipping and storing hazardous materials or food-safety containers.

Since the box has a coarse surface and relatively thick and spongy material, it can be challenging to apply fine graphic printing. Typically, it is printed using a flexographic process, which is naturally coarse and has loose registration properties. Hybrid techniques are used to overcome this challenge. One such technique is "Single-Face Laminate" (SFL), which uses a single liner board (single-face corrugated cardboard). Instead of a second long-fibered liner, a pre-printed sheet of paperboard, such as SBS C1S, is laminated to the outer facing.
