Due to the high number of flutes per square meter, the surface crushing resistance is high. It gives a clear printing surface in printed boxes compared to other corrugated types. Printed cardboard is laminated and used directly as a product box.

Flute Height: 1.0 – 1.8 mm

Wave Length: 3.0 – 3.5 mm

Number Value of Flutes: 285 – 334

Corrugated Coefficient Value: 1.22 – 1.29

Same as E flute, the surface crushing resistance is high due to the high number of flutes per square meter. It gives a clear printing surface in printed boxes compared to other corrugated types. Printed cardboard is laminated and used directly as a product box.

Flute Height:  2.5 – 3.0 mm

Wave Length: 5.5 – 8.5 mm

Number Value of Flute: 153 -181

Corrugated Coefficient Value:  1.30 – 1.39

It has widespread usage in recent years. It is preferred because of the high number of flutes instead of the A flute manufactured before. It is a type of corrugated cardboard with high carrying capacity which also gives good results on printed surfaces.

Flute Height: 3.2 – 4.0 mm

Wave Length: 6.8 – 8.0 mm

Number Value of Flute: 125 – 147

Corrugated Coefficient Value: 1.42 – 1.50

The composition of the E and C flute, consisting of five papers, is highly efficient in packaging for external protection and transportation. The use of the E flute on the outer surface creates an efficient surface for printing.

Wall thickness: 4.2 – 5.8 mm

The composition of the C and B flute, consisting of five papers, is thick-walled due to the flute height, allowing it to carry the loads on the vertical very well. B flute being on the outer surface creates an efficient surface for printing.

Wall thickness: 5.4 – 7.0 mm
