Corrugated vs. Cardboard

The term "cardboard box" is commonly misused when referring to a corrugated box. The correct technical term is corrugated fiberboard carton.

Cardboard boxes are really chipboard boxes, and used primarily for packaging lightweight products, such food boxes, or board games.

Corrugated fiberboard boxes are widely utilized in retail packaging, as shipping cartons, as product displays and many other applications requiring lightweight, and strong materials materials.

Facts About Corrugated Flutes

Corrugated board can be created with several different flute profiles. The five most common flute profiles are:

  • A-Flute: Contains about 33 flutes per foot.
  • B-Flute: Was developed primarily for packaging canned goods. Contains about 47 flutes per foot and measures 1/8" in height.
  • C-Flute: Is commonly used for shipping boxes.. Contains about 39 flutes per foot and measures 5/32" high.
  • E-Flute: Contains about 90 flutes per foot and measures 1/16" thick
  • F-Flute: Developed for small retail packaging. Contains about 125 flutes per foot and measures 1/32" thick

Generally, larger flute profiles deliver greater vertical compression strength and cushioning. Smaller flute profiles provide enhanced structural and graphics capabilities for use in retail packaging.

Different flute profiles can be combined in one piece of combined board. For example, a triplewall board may contain one layer of A-flute medium with two layers of C-flute medium. Mixing flute profiles allows designers to adjust compression strength, cushioning strength and total thickness of the combined board.
