How Double Wall Boxes Protect Fragile or Bulky Shipments
Double wall protection for fragile and bulky items: how the extra layer makes the difference.
How double wall protects
Quick answer
Double wall boxes absorb roughly twice the impact energy and resist twice the compression of single wall. The two fluted layers each compress independently on impact, absorbing more energy before force reaches the contents. Three liner papers resist puncture from external impacts and internal sharp edges. For fragile heavy items (electronics, glassware, machinery parts), the extra protection justifies the 30-50% cost premium over single wall.
