BOARD GRADES WE HOLD IN STOCK

Board grades / Corrugations

The wave shapes, or ridges, that are pressed into a sheet of material that have been softened by steam. This material is then sandwiched between flat sheets of material to form corrugated fibre-board. Corrugation serves as protective cushioning and helps strengthen a carton. Different widths and configurations offer distinctive performance advantages, ask our sales team if you need help in selecting an appropriate board grade for you.
The three below corrugations are what we use to make single wall, general-purpose cartons:

B-Flute : Flute thickness of 2.5 mm
C-Flute : Flute thickness of 3.6 mm
E-Flute: Flute thickness of 1.5 mm

B-Flute has good puncture resistance
C-Flute has the optimum combination of both.
E-Flute has excellent stacking Strength, it is generally used for light applications and die-cut boxes such as Pizza Boxes, Mailers, Shoe boxes and alike.
