Corrugated Boxes for Export: The Basics
Export cartons work harder than domestic ones: longer transit, more handling points, humidity at sea and heavy container stacking. That usually means higher ply and GSM, moisture-aware storage before stuffing, and clear standard handling marks printed on the carton so every handler treats it right.
Board choices for export
- Heavier builds are common: 5 ply as a floor, 7 ply for dense or machine loads.
- Discuss the route with your unit. Sea transit in monsoon months argues for stronger, drier board.
- For stacking in containers, ask about edge crush performance, not just bursting strength.
Standard handling marks
| Mark | Tells the handler |
|---|---|
| Fragile (glass symbol) | Contents break, handle gently |
| This way up (arrows) | Keep the carton upright |
| Keep dry (umbrella) | Protect from rain and moisture |
| Handle with care | General caution in handling |
| Weight marking | Gross weight for safe lifting |
Marks are cheap to print and expensive to skip. They are also expected by freight handlers worldwide, which is why they follow standard symbols rather than free text.
Preparation that pays off
Condition cartons in dry storage before packing, strap or wrap palletised loads so cartons cannot shift, and keep carton weight within what one handler can safely move where manual handling is expected. If your buyer specifies carton requirements, share that document with the unit before production, not after.
Frequently asked questions
Do export boxes need different paper?
Often heavier and better grade, chosen for humidity and long stacking. The route and cargo decide.
Are printed handling marks mandatory?
Requirements vary by buyer and cargo, but standard marks are expected practice in export packing.
Should export cartons be palletised?
Container stuffing is done both ways. Palletising costs space but speeds handling and protects cartons.
