Do Corrugated Boxes Need Cushioning?
Entity Coverage
Corrugated boxes need cushioning whenever the product can move, crush, or drop — the box wall alone does not absorb shock. Fragile items need void fill or inserts; sturdy items can ship loose. This answer explains the rule.
| Product | Cushioning? |
|---|---|
| Fragile, glass | Yes, inserts or fill |
| Electronics | Yes, suspension |
| Sturdy, solid | Minimal or none |
| Heavy, dense | Load deck, not fill |
