Did you just start a business and need custom packaging for your product? If so, Bolt Boxes is here to help. If you want to design a custom box — whether for e-commerce shipping, mailing or transporting heavy or fragile items — it’s essential to learn about the different types of packaging required for the job.
While cardboard boxes are commonly used for packaging small items — think cereal boxes — the corrugated board is used to transport heavier objects due to its strength and durability. Corrugated boards contain both a liner and a medium. While the liner is the flat material typically found on the outside surfaces of the board, the medium can be found between the liners and creates the arch shapes, or “flutes.”
Flutes are significant contributors to the overall strength of the board and can affect its performance, weight and cost. The weight and type of material you desire to ship will help you determine the appropriate flute type. Knowing the difference between various flutes will help you decide which cardboard thickness would be best for your custom box.
The material flute is the corrugated or curved section between the two liners, and by changing its height, it’s possible to achieve different performance characteristics in the cardboard.
Because different flute types signal a variation in packaging weight, different sizes are used to create boxes for all kinds of merchandise — both heavy and light. For example, very fine flutes denoted as “E” material flutes are used to manufacture lightweight retail cartons. A more coarse material flute like an “A” or “B,” on the other hand, is most often used for transit packaging.
Using double-walled material, manufacturers can combine one or more flutes to create a grade such as “EB” or “BC” flute. Combining one or more material flutes can have several purposes, including to improve the outer appearance of a printing surface and create a rigid structure that’s perfect for more substantial items.
Material flutes are most often manufactured from a waste-based fluting, or WBF. These materials have been fully recycled. Flutes can also be constructed from semi-chem fluting, or SC material. Commonly used flute sizes are as follows:
