What Are Cardboard Flutes?

Cardboard flutes are the reinforcing structures inside corrugated cardboard, and they give the box material its thickness. The outer liners get added reinforcement from the fluting to form a more secure packaging material. Placed between the top and bottom layers of the cardboard, the flute’s wave-shaped structure creates additional cushioning and durability for the box.

Along with providing more strength, the fluting also serves as insulation against outside shocks and vibration. The central flute layer can come in various thicknesses to provide the specific rigidity and insulation needed for unique cardboard applications. From displays to freight packages, cardboard flutes can provide enhanced protection and security and are a key part of boxes’ overall structures.

Box types can use flutes in a few different ways, such as:

  • Single face: This type of box has one liner attached to the fluting, leaving flutes exposed on one side.
  • Double face: Using three liners, this option consists of two layers of fluting with liners on either side and in the middle for extra durability.
  • Single wall: This option uses one layer of fluting and two liners, one on either side.
  • Double wall: As the strongest type of corrugated cardboard, this option has three liners — two on the outside and one in the middle. Two layers of fluting, separated by a liner, go between the outer liners to reinforce them.

Common Flute Sizes

Cardboard boxes come in different types of flutes, so you can choose the best fit for your applications. You have a few primary options to evaluate as you select the right features for your packaging needs.

Thicker, heavy-duty materials have more flutes per foot and, as a result, are also wider, with the flute waves being tighter and higher.

E Flute Cardboard Boxes

The flattest option of cardboard fluting, the E type, has a compact design ideal for printing and folding. If you need a box material that’s easy to fold and can hold lightweight items, E fluting may be the right choice for you. Typical applications for this material include packaging for cosmetics products and other smaller objects.

C Flute Cardboard Boxes

C fluting is the most robust option available for more heavy-duty packaging needs. It’s also one of the most commonly used types of corrugated cardboard because of its durability and versatility. This material features thicker fluting that can reliably protect more fragile items like glass. C fluting is also a popular choice for heavier applications such as furniture, as it allows for durable protection and easy stacking.

B Flute Cardboard Boxes

B flute boxes are a common choice for marketing applications. With a thinner, more compact design that improves printability, this solution can provide durable product protection and make customized designing easier. B fluting materials are puncture- and crush-resistant and have a higher arch size, but they still have a relatively thin wall thickness. This material is popular for various display and storage requirements for items such as canned goods.
