Descrição
Protection Is a Balance
An insert’s job is simple: hold the product and protect it. But how thick should it be?
Too thin and the product rattles or breaks. Too thick and you’re paying for material you don’t need.

The Cost of Over-Protection
Thicker insert = more material = higher cost.
If your product doesn’t need 20mm foam, you’re wasting money. A 5mm cardboard insert might be enough.
Common Protection Mistakes
- Too thin — Product breaks in shipping
- Too thick — Wasted material cost
- Wrong density — Soft foam for a heavy product
- Sem proteção nos cantos — Corners crush
- Bottom only — Sides aren’t protected
- Not testing — Always drop-test your packaging
