In sea freight, packaging is not just about wrapping goods—it directly affects damage risk, customs handling, and even shipping cost. Containers travel long distances, pass through multiple terminals, and get handled more than once. Weak packaging often shows problems only after arrival.
Most cargo issues in international shipping start much earlier than expected: at the packing stage.
1. Choose the Right Carton or Crate
Not all packaging is equal.
For sea freight, cartons should be:
Strong double-wall or triple-wall corrugated boxes
Sized to fit products tightly (avoid empty space)
Resistant to stacking pressure
For heavier or fragile cargo, wooden crates or pallets are often safer. They handle pressure and vibration better during long ocean transit.
2. Control Moisture and Humidity
Sea transport means exposure to changing humidity levels.
Simple protection methods include:
Using plastic liners inside cartons
Adding desiccant packs (dry agents)
Wrapping cargo with shrink film
Sealing all openings properly
Moisture damage is one of the most common issues in ocean freight, especially for electronics, textiles, and paper products.
3. Reinforce Pallet Loading
Palletizing makes handling easier, but only if done correctly.
Key points:
Keep weight evenly distributed
Avoid overhanging cartons
Use stretch film tightly wrapped from base to top
Add corner protectors for stability
Poor pallet stacking often leads to crushed cartons during container loading or unloading.
4. Label Everything Clearly
Clear labeling helps prevent confusion during transit and customs inspection.
Each package should show:
Product name or SKU
Quantity
Handling instructions (e.g., “Fragile,” “Keep Dry”)
Destination information
Even simple labels reduce misrouting or mishandling risks.
5. Avoid Overpacking or Underpacking
There’s a balance between protection and efficiency.
Overpacking increases CBM and shipping cost
Underpacking increases risk of damage
Good packaging fits the product properly without wasted space but still allows protection against impact.
6. Test Packaging Before Bulk Shipping
A quick drop test or vibration test can reveal weak points before shipment.
Many shippers skip this step, but it often prevents costly surprises after arrival.
Shipping packaging is often underestimated, but in sea freight it plays a direct role in cargo safety and total landed cost. Strong, well-planned packaging reduces damage claims, avoids delays, and improves overall shipping efficiency.
In long-distance logistics, good packaging is not extra—it’s part of the shipping strategy.
