What Is Corrugated Board?
Corrugated board consists of one or more fluted (wavy) layers sandwiched between flat linerboards.
This structure gives packaging both light weight and strength — ideal for shipping boxes and industrial packaging.
Single-wall: e.g., B flute, C flute
Double-wall: e.g., BC flute, AB flute
Triple-wall: e.g., BCB flute
Common Corrugated Flute Types
| Flute Type | Thickness (mm) | Features |
|---|---|---|
| A-Flute | ≈ 4.8 – 5.0 | Excellent cushioning and stacking strength; used for fragile goods. |
| B-Flute | ≈ 2.5 – 3.0 | Good puncture resistance and surface printing; common in retail packaging. |
| C-Flute | ≈ 3.5 – 4.0 | Balanced between cushioning and rigidity; the most widely used flute. |
| E-Flute | ≈ 1.2 – 1.8 | Thin and smooth; ideal for small boxes and detailed printing. |
| EB-Flute | ≈ 4.0 – 4.5 | Double-wall combining E and B for strength and fine print surface. |
| BC-Flute | ≈ 6.0 – 7.0 | Very strong double-wall for heavy-duty packaging. |
| BCB-Flute | ≈ 9.0+ | Triple-wall for industrial and export shipping cartons. |
Honeycomb Board
Honeycomb board uses a hexagonal core structure between paper liners.
It provides excellent compression strength while remaining lightweight — perfect for furniture, pallet systems, and protective packaging.

Common Honeycomb Thickness
| Type | Typical Thickness (mm) | Typical Applications |
|---|---|---|
| Ultra-thin Type | 5mm – 10mm | Lightweight packaging, display panels, inner liners, cushioning layers |
| Standard Type | 15mm – 30mm | Regular shipping boxes, buffer boards, pallet tops |
| Thickened Type | 40mm – 60mm | Furniture panels, door cores, machinery protection packaging |
| Heavy-duty Structural Type | 70mm – 100mm (customizable up to 150mm) | Large pallets, appliance shells, replacements for wood or foam boards |
