Bundles
Freight| Construction | Thickness | Typical max weight | Stacking | Typical use |
|---|---|---|---|---|
| Single wall C | 5/32" (4.0 mm) | 65 lb | Not for bulk | Lids, layer pads, dividers |
| Double wall BC | 9/32" (7.1 mm) | 900 – 1,200 lb | 1 high loaded | General bulk under 1,200 lb |
| Double wall CC | 5/16" (7.9 mm) | 1,000 – 1,300 lb | 1 high loaded | Slightly better cushioning than BC |
| Triple wall BCC | 7/16" (11.1 mm) | 2,200 – 2,500 lb | 2 high loaded | The bulk workhorse |
| Triple wall ACC | 1/2" (12.7 mm) | 2,400 – 2,700 lb | 2 high loaded | Dense product with cushioning need |
| Five wall AAC | 5/8" (15.9 mm) | 3,000 lb+ | 3 high, matched pallets | Castings, stampings, export |
| Measure | Imperial | Metric | Notes |
|---|---|---|---|

| Triple wall thickness | 7/16 in | 11.1 mm | Takes about 7/8 in off interior width across both walls. |
| Typical capacity | 2,200 lb | 998 kg | Triple wall BCC, evenly distributed, matched pallet. |
| Container cube at 36" | 33.3 ft³ | 0.943 m³ | Outside dimensions, before board thickness. |
| OCC bale | 1,000 – 1,400 lb | 454 – 635 kg | Typical bale from a horizontal baler. |
| Trailer capacity, knocked down | 400 – 600 units | — | 53-foot dry van; cube limited, never weight limited. |
| Moisture ceiling for OCC | 12% | 12% | Above this you are selling water at a penalty. |
