BC flute offers exceptional protection for fragile items during shipping and handling. Its double-wall construction provides durability while minimising the risk of damage, making it ideal for heavy or delicate products.

EB flute stands out for its ability to showcase vibrant graphics and intricate designs due to its enhanced printing capabilities. Despite being slightly thinner than BC flute, EB flute maintains a good level of strength, making it a popular choice for retail packaging where visual appeal is crucial.

C flute strikes a balance between strength and printability, making it one of the most commonly used grades in corrugated cardboard packaging. Its medium thickness offers adequate cushioning for various products while still allowing for high-quality printing.

B flute is prized for its stacking strength, making it suitable for products that require sturdy and stable packaging during transit and storage. Although not as thick as BC flute, B flute provides reliable protection without sacrificing print quality, making it a versatile option for many industries.

M flute offers a lightweight alternative with decent strength, making it suitable for applications where minimising package weight is crucial, such as shipping large volumes of products. Despite its thinner profile, M flute maintains structural integrity, ensuring products remain secure during transit.

E flute excels in delivering sharp and vibrant printing on a thinner board, making it an excellent choice for packaging designs that require intricate details and vivid colours. Its thinner construction also contributes to reduced shipping costs and environmental benefits due to lower material usage.
