Box Materials Explained

Corrugated board is available in many different paper combinations and flutes (refer diagram below), the most appropriate combination is determined from our technical sales and design team’s understanding of your product and the associated supply chain that your product goes through, this would include all aspects of the products palletising, storage, transport and distribution requirements. Again, dependant on your product application, we can use either recycled or kraft papers for your corrugated packaging solution. Our aim is to ensure your packaging is well protected, whilst not costing the earth.

To give you an understanding of the different flutes that are available, we have listed the standard flute types that are available through Quick Brown Box.



SINGLE FACE   (approx. thickness 3.0 mm)

Used for single face rolls or single face divider pads. The single face product is mainly used for protection in wrapping those awkwardly shaped items.


F Flute   (approx. thickness 1.0 mm)

 Creative Packaging Materials F flute

Used for display packaging. Often used with litho laminated high graphically printed cartons, where print quality and presentation is paramount. Also referred to as microflute.


E Flute   (approx. thickness 1.5 mm)

 Creative Packaging Materials E flute

Used for display packaging. E flute is thicker than F flute, and can be used where slightly more product support is required.


B Flute   (approx. thickness 3.0 mm)

 Creative Packaging Materials B flute

B flute is the second most commonly used flute. It has a higher puncture resistance than thinner flutes, and will consume less space on a pallet load than bigger flutes due to the reduced flute. This flute is used for self supporting products as well as being used extensively for die-cut cartons, including high speed wrap-around cartons.

C Flute   (approx. thickness 4.0 mm)


C flute is the most commonly used flute, it has a higher stacking strength than other single wall flutes. This flute is mainly used where the product is not self supporting and requires the carton to provide the vertical support.


BC Flute   (approx. thickness 6.0-7.0 mm)

BC flute is used for those heavier applications, where the product maybe bulky or carry some weight that requires a higher degree of protection. This flute has both excellent stacking and puncture resistance.

AAC Flute   (approx. thickness 15.0 mm)

Creative Packaging Materials ACC flute

AAC flute is often referred to as tri-wall and is used extensively in the produce market for carrying bulk pallet loads of fruit and vegetables. Also used for packing large industrial machinery, especially where maximum product protection is required during distribution.
