Fluting
The various flutes available offer different properties over each other such as Compression, Crush or Burst strength, Printability or storage space.
E Flute
Board thickness approximately 1.2mm.
A fine flute which gives an excellent crush resistance and printability
B Flute
Board thickness approximately 3mm.
The most widely used flute profile due to its all round compression strength, compactness, printability and cost effectiveness.
C Flute
Board thickness approximately 4mm.
A larger flute than ‘B’ offering greater compression strength, but can be more easily crushed.
BC Flute
(Double wall)
Board thickness approximately 7mm
A combination of ‘B’ and ‘C’ flute is normally used when compression and stacking strength is important.
EB Flute
(Double wall)
Board thickness approximately 4.2mm.
A combination of ‘E’ and ‘B’ flute offering good strength and printability taking up less storage space than ‘BC’.
