Introduction
Triple wall corrugated boxes represent the heaviest-duty packaging solution in the corrugated industry. With seven layers of protection, these boxes handle products that would destroy standard packaging. If your products weigh over 50 kg or face extreme handling conditions, triple wall is the answer.
What is Triple Wall Corrugated?
Construction and Structure
Triple wall corrugated boxes have three corrugated mediums and four liner boards:
- Outer liner: External protection layer
- First corrugated medium: First flute layer
- Middle liner: Central support layer
- Second corrugated medium: Second flute layer
- Inner liner: Product contact layer
- Third corrugated medium: Third flute layer
- Inner bottom liner: Final protection
Flute Combination Options
| Combination | Total Thickness | Weight Capacity | Best For |
|---|---|---|---|
| BC-BC | 15-18mm | Up to 100 kg | Heavy machinery, industrial equipment |
| BC-AC | 16-19mm | Up to 120 kg | Very heavy industrial applications |
| AC-AC | 17-20mm | Up to 150 kg | Extreme weight applications |
