When buying carbon black, attention usually goes to the choice of grade and the packaging decision is left until last. Yet packaging directly affects unit cost, handling labor, storage space and even product quality.
Two options
Jumbo bag (PP-PE, double valve), 1,000 kg
Designed for high-volume production. The double-valve design allows both filling and discharging without releasing dust.
| Unit | Quantity |
|---|---|
| Bag weight | 1,000 kg |
| Per pallet | 1,000 kg |
| 20' container | 10 pallets, 10,000 kg |
| 40' container | 20 pallets, 20,000 kg |
| Truck | 22 pallets, 22,000 kg |
Two-ply kraft paper-PE bag, 20–25 kg
For small-batch production, trials and plants with limited handling equipment. The bag weight varies by grade.
| Grade | Bag | Pallet | 20' FCL | 40' FCL | Truck |
|---|---|---|---|---|---|
| N220 · N234 | 20 kg | 1,100 kg | 8,800 kg | 17,600 kg | 19,800 kg |
| N330 | 22 kg | 1,210 kg | 9,680 kg | 19,360 kg | 21,780 kg |
| N339 · N375 · N550 | 21 kg | 1,155 kg | 9,240 kg | 18,480 kg | 20,790 kg |
| N326 · N660 · N772 | 25 kg | 1,375 kg | 11,000 kg | 22,000 kg | 22,000 kg |
Decision criteria
1. Your handling equipment
Jumbo bags need a forklift and a lifting frame. Without them, paper bags are the only option. In plants with a jumbo bag discharge station, on the other hand, paper bags mean unnecessary labor.
2. Your consumption rate
This is the most overlooked criterion. An opened jumbo bag should be used up within a reasonable time; a bag left half-open for months risks picking up moisture, and its heating loss value rises. For a plant that does not use a pallet a week, paper bags are the safer choice.
3. Cost
Jumbo bags lower the packaging cost per unit. They also let you ship more tonnage per container: 10,000 kg in a 20' FCL with jumbo bags, 8,800–11,000 kg with paper bags. On long-distance shipments, the difference feeds directly into the freight cost.
4. Storage space
Jumbo bags take up less floor space and stack more neatly.
Storage conditions
- A closed, dry area out of direct sunlight.
- On pallets that keep the packaging off the floor, to prevent moisture transfer.
- Do not exceed the strength limit of the packaging when stacking.
- Close the opening of a jumbo bag again after use.
- Provide dust control and ventilation.
Custom packaging
The manufacturer can customize packaging to customer needs: a different bag weight, special labeling or a different pallet pattern can be requested. If you have a non-standard requirement, simply state it at the quotation stage.
