Corrugated Board — E-Flute, B-Flute & BC Double-Wall

What Is Corrugated Board?

Corrugated board (also called corrugated cardboard) consists of a fluted corrugated sheet sandwiched between two flat linerboards. The fluted layer provides cushioning and structural strength, while the liners provide a printable surface.

Flute Profiles

E-flute (1.5mm): The finest profile. Used for premium retail boxes, mailer boxes, and high-quality print applications. Excellent crush resistance for light goods.

B-flute (3mm): The most versatile profile. Ideal for canned goods, die-cut packaging, and point-of-sale displays. Good stacking strength.

C-flute (4mm): The standard shipping flute. Best for general-purpose shipping boxes and produce packaging.

BC double-wall (6mm): Combines B and C flute for maximum strength. Used for heavy industrial goods and export packaging.

Sustainability

Corrugated board is one of the most sustainable packaging materials: 80–90% recycled content, 100% recyclable, and FSC-certified grades available.

Corrugated board is the primary structural material for shipping and retail packaging. It consists of a fluted inner layer sandwiched between flat linerboards.
