What board grade do I need?
When selecting a board grade you must factor in the following; Storing Conditions, Product weight and the desired aesthetic finish. If your products will be stacked on a pallet many don’t consider the huge compression forces applied to the lower boxes. If the compressive load becomes too great the boxes can crumple and in some cases higher boxes topple off the pallet.
Please view the table below for an approximate guideline when selecting your strength. Please note that the maximum capacity can differ depending on the width & length of your box.
| B Flute (Single Wall) | |
| Grade | Weight capacity |
| 125 Kraft / 125 Test | – 5 Kilograms |
| 150 Kraft / 150 Test | – 10 Kilograms |
| 200 Kraft / 200 Test | – 15 Kilograms |
| B/C & E/B Flute (Double Wall) | |
| Grade | Weight capacity |
| 125 Kraft / 125 Test | – 15 Kilograms |
| 150 Kraft / 150 Test | – 20 Kilograms |
| 200 Kraft / 200 Test | – 30 Kilograms |
| 300 Kraft / 300 Test | – 40 Kilograms |
Cardboard is constructed from three components. The ‘inside liner’. Which is ordinarily ‘Test’. Which is recycled paper. Then in the middle there is a corrugated ‘fluting’. The strength of this is also customizable. Finally, the ‘outside liner’, which is normally ‘Kraft’. This is slightly more aesthetically pleasing than ‘test. Furthermore, it provides a better canvas for printing. This is because test is marginally thinner and the ink saturates the liner.
B flute provides maximum storage efficiency, moderate strength and best cost efficiency. It is 2.8mm thick. E/B flute provides a combination of warehouse space efficiency and strength. It is 4mm thick. B/C Flute delivers excellent strength and great printability however you can’t get as many on a pallet as it is 6.4mm thick so they will take more warehouse space.
We can offer our bespoke cardboard boxes in a wide range of board grades. We can manufacture them with Kraft (Brown Paper), Test (Brown) and White liners, which can be produced with a glossy finish. The grades stated above are popular liners and grades. We can supply our boxes in various combinations of board grades and liners.
