Description
Poor Palletization Destroys Good Boxes
Your corrugated boxes are strong enough — but if they’re stacked wrong on a pallet, the whole load collapses in transit. Interlocking vs column stacking, stretch wrap tension, pallet overhang and stack height all matter. Get palletization right and your boxes arrive intact.

Interlocking Stack
The most stable pattern:
- Each layer rotated 90 degrees
- Boxes interlock like bricks
- Resists shifting during transport
- Slightly reduces stack strength (box corners share load)
Best for: Mixed box sizes, long-distance shipping, less-than-truckload (LTL).
Column Stack
The strongest pattern:
- Boxes stacked directly above each other
- Maximum box-to-box compression strength
- Less resistant to shifting
- Requires stretch wrap to hold together
Best for: Uniform box sizes, truckload (TL), short-distance moves.

Stretch Wrap Guide
|
Factor
|
Recommendation
|
|
Wrap thickness
|
20–25 micron for light loads, 30–50 micron for heavy
|
|
Wrap turns
|
Minimum 4 turns at top and bottom, 1 turn per layer in middle
|
|
Film width
|
500mm standard
|
|
Tension
|
Tight enough to hold, not so tight it crushes top boxes
|
|
Top sheet
|
Add dust cover for outdoor storage
|
Maximum Stack Height
|
Box Strength
|
Max Stack Height
|
|
Single wall (E/B flute)
|
2–3 layers
|
|
Double wall (BC flute)
|
4–6 layers
|
|
Triple wall
|
8+ layers
|
Rule of thumb: never stack higher than 2 meters for standard double-wall boxes. Beyond that, use double-stacked pallets or bulk racks.
Common Palletization Mistakes
- Boxes overhang the pallet — Edges get crushed by forklift
- Column stack without wrap — Load shifts and collapses
- Heaviest boxes on top — Top boxes crush bottom boxes
- Gap between layers — Boxes sink and warp
- No corner boards — Pallet corners crush under pressure
- Under-wrapped load — Boxes fall off during transport
How We Help
We design corrugated boxes that work with your pallet dimensions:
- Calculate box sizes to maximize pallet fill (reduce empty space)
- Recommend board strength based on your stack height
- Advise on corner boards and edge protectors
- Provide packing diagrams for your warehouse team
