For a quick answer, here is a comparison table:
| Box Type | Approx. Weight |
|---|---|
| Small single-wall box | 5 - 10 kg |
| Medium single-wall box | 10 - 15 kg |
| Large single-wall box | 15 - 20 kg |
| Double-wall box | 20 - 40 kg |
| Reinforced industrial box | 40 - 60 kg or more |
These values are approximate and may vary by manufacturer.
Factors That Determine Strength
Not all boxes have the same strength:
1. Cardboard Type
- Single-wall: Supports 5-15 kg.
- Double-wall: Supports 20-40 kg.
- Triple-wall: Can support over 50 kg.
2. Box Size
Larger boxes deform more easily.
3. Material Quality
Virgin fiber cardboard is stronger than recycled.
4. Packaging Method
A properly sealed box supports more weight.
Moving Box Weight
Moving boxes support 15-30 kg. Recommended max: 20 kg.
How to Check Strength
✅ Checklist
- No holes or tears
- No moisture
- Intact corners
- Reinforced base
- Proper tape
Signs of Overload
- Bowed walls
- Corner deformation
- Sagging bottom
- Tape peeling
- Creaking when moved
Reinforcement Tips
💡 Reinforce with Tape
Use industrial packing tape on the base and corners.
📦 Distribute Weight
Place heaviest items at the bottom.
🛡️ Double Wall
Double-wall boxes are much stronger.
❓ FAQ
Généralement entre 5 et 10 kg, selon l'épaisseur du carton.
Entre 20 et 40 kg, selon la qualité du carton et la taille.
Pas nécessairement. Les grandes boîtes se déforment plus facilement avec des objets lourds.
Les petites boîtes renforcées sont la meilleure option pour transporter des livres.
Conclusion
Load capacity depends on cardboard type, size, and quality.
📦 Summary
Use reinforced boxes, distribute weight, and avoid moisture.
