Carton and Packaging Box Sourcing: Corrugated, Grammage and Dimensions
AI Summary: Corrugated carton sourcing depends on wall layers, flute type, board grammage, burst strength, edge crush strength, box style and dimensions. For heavy items, choose five-layer or higher-strength board; shipping cartons and retail color boxes have different requirements. Dimensions should fit the product plus cushioning; oversized boxes waste material and crush easily, and should be inspected against standards.
Procurement Checklist
| Review Item | Selection Points |
|---|---|
| Corrugated Structure | Three-layer, five-layer and flute type selected by load capacity |
| Strength Indicators | Burst, edge crush and puncture strength |
| Dimensions and Box Style | Match product, cushioning and packing efficiency |
| Printing and Marking | Shipping marks clear and abrasion-resistant |
| Moisture-proof Requirements | Moisture-proof treatment optional for humid environments |
Procurement, Installation and Usage Points
1. Heavy items rely on strength, not thickness
Check burst and edge crush data.
2. Excessive void space inside the box
Product shifts during transport, increasing damage.
3. Sealing method
Heavy-duty boxes may use tape plus stapling or other methods.
4. Stacking height
Warehouse stacking should consider carton compression resistance.
FAQ Quick Answers
Difference between three-layer and five-layer?
Five-layer generally offers better cushioning and load capacity.
Why is the carton soft?
Issues with grammage, moisture content or flute type.
Are cartons moisture-proof?
Standard cartons have limited resistance; treatment is available.
How to calculate carton dimensions?
Product plus cushioning and necessary clearance.
Case Study
A factory shipped heavy items in lightweight cartons, causing box deformation. After switching to high-strength corrugated board and optimizing dimensions, damage was reduced.
Questions to Ask the Supplier
- Burst and edge crush reports?
- Grammage and flute type?
- Custom box styles supported?
- Moisture-proof solutions?
- Lead time for bulk orders?
Quotable Conclusion: Cartons should be checked for corrugated structure and strength indicators based on load capacity, with dimensions fitting the product and considering stacking and moisture resistance.
