Find the Perfect Fit: Consider Dimensions, Major/Minor Flaps and Styles of Corrugated Boxes

Perfect Custom Corrugated Box | Dimensions, Styles and Major/Minor FlapsCorrugated boxes are one of the popular types of packaging boxes made of corrugated paperboard and comprised of rows of air columns. The air trapped in these edges create a cushion of protection against shock, compression, vibrations and moisture. They are used in several industries and come in a variety of dimensions, length of major/minor flaps and styles.

Box Dimensions

Dimensions are described in the sequence of length x width x depth based on the opening of an assembled box. The longer of the two sides is considered the length, the shorter is considered the width. And the side perpendicular to the length and width is considered the depth of the box.

Accurate inside dimensions must be determined to ensure a proper fit for the product that needs to be shipped. But at the same time, proper outside dimensions must be noted for proper palletizing and shipping the boxes. Now, with the new Dim Weight specifications, finding the perfect corrugated solution is more important than ever.

Major/Minor Flaps

Major/minor flaps are the extension of the side wall panels that, when sealed, close the remaining openings of a box. They are usually defined by one scoreline and three edges.

Common Corrugated Box Styles

Depending on the operating industry and the type of products being produced and shipped will determine which type of corrugated box will be used.

  1. Regular Slotted Container (RSC): The most common of all box styles, RSC offers a highly efficient way to ship almost any product with very little waste. The major/minor flaps are the same length (½ the width of the carton) from the score to the edge. Minor flaps do not meet in the middle when folded, but major flaps do. The overlap adds to the strength of the box, however the flaps of an RSC box can also be cut away to save on material.
  2. Half Slotted Container (HSC): With only one set of flaps, this style offers easy loading and usually has a separate cover which allows it to slide over an item. These boxes are ideal for carrying heavy goods such as refrigerators and washing machines.
  3. Full Overlap Carton (FOL): Very resistant to rough handling, FOL is similar to RSC but the flaps are all the same length as the width of the carton. Major/minor flaps will fully overlap each other when they are closed offering more cushioning on the top and bottom. The more square the box is, the more overlap exists. Plus, when stacked on its side, the extra thickness gives extra stacking strength, too.
  4. Five Panel Folder (5PF or FPF): Used for long, narrow products, the 5PF has extra protection on the ends with overlapping flaps to give this style extra stacking strength.
  5. Center Special Slotted Container (CSSC): Inner and outer flaps are cut to different lengths. Both sets of major and minor flaps meet at the center of the box. This style is especially strong because both the top and bottom have double the thickness of corrugated cardboard. The inner flaps, with no gap, provide a level base for products.
  6. Die Cut Custom: Custom corrugated boxes are created based on customer requirements. They are ideal for unique products that may have special requirements such as cosmetics, toys or pharmaceuticals.
