Descrição

A Bad Pallet Load = Broken Boxes

You chose the right box size, printed it perfectly, packed it well — but if it falls over on the pallet, everything arrives damaged. Proper pallet stacking and stretch wrapping is the last line of defense between your boxes and the freight truck.

Stacking Patterns

Pattern	How It Works	Força	Ideal para
Column stacking	Boxes stacked directly on top of each other	Strong vertical compression	Heavy products, stable boxes
Interlocking (brick pattern)	Each layer rotated 90 degrees	Better interlock, less vertical strength	Light-medium products
Pinwheel pattern	Four boxes rotated in a circle	Good stability for odd sizes	Mixed size boxes

How High to Stack

Box Strength	Max Stack Height
32 ECT single wall	5–6 layers
44 ECT single wall	6–8 layers
55 ECT double wall	8–10 layers
67 ECT double wall	10+ layers

Rule: The bottom boxes carry all the weight. Don’t stack more than your box strength allows.

Stretch Wrapping

Stretch wrap holds the load together:

8–12 wraps around the pallet

Overlap 50% between layers

Tight at the bottom, slightly looser at top

Cover the bottom 6 inches and top 6 inches

Use 80–120 gauge stretch film

Common mistake: Too few wraps — load shifts and falls.

Pallet Size

Pallet Type	Tamanho
Standard US pallet	48″ × 40″ (1219 × 1016mm)
Euro pallet	800 × 1200mm
Standard UK pallet	1200 × 1000mm

Your boxes should fit the pallet with minimal overhang. Overhang = crushed corners.

Load Stability Check

Before shipping:

Push test — Push the top of the load. Does it wobble?

Tilt test — Tilt pallet 5 degrees. Does anything shift?

Bottom check — Are bottom boxes bulging or crushed?

Wrap check — Is stretch wrap tight and complete?

Common Palletizing Mistakes

Overhang — Boxes hang off pallet edges = crushed corners

Too many layers — Bottom boxes crush under weight

No stretch wrap — Load falls apart in transit

Boxes not aligned — Uneven stack = unstable

Heavy boxes on top — Heavy on light = crushed bottom

Gaps in the stack — Empty spaces = load collapses

No corner boards — Light loads need edge protection

Mixed sizes randomly — Unstable stack = falling boxes

Pallet Cost Impact

Mistake	Cost Impact
Load falls over in transit	100% damage to that pallet
Crushed corners	5–10% of boxes damaged
Broken stretch wrap	Load shifts, boxes rub together
Wrong pallet size	Overhang damage, wasted space
