FLUTE TYPE AND BOARD GRADE CUSTOMISATION

GreenBean is able to provide a combination of flute type and board grade to meet your needs.

Flute is the height of the corrugation which is placed between two liners. The most common flute used in slotted containers is 'C' and it has excellent stacking strength at 4mm of thickness.

The next most common flute type is mainly used in diecut applications. Named 'B', it has good burst strength properties at a thickness of 3mm.

The combination of these two flute types, form a product widely known as twin cushion, or double wall. The thickness of this product is around 9mm.

There are other flutes types, known as 'A', 'E', and 'F', which are not used as often are used specifically for specialised applications. Any of our materials manufactured can be produced in both white or brown material.
