Heavy-Duty Corrugated Shipping Boxes
Also called: double-wall shipping box · heavy duty carton · export shipping box
Double wall construction for contents that punish a standard carton: dense items, awkward shapes, long multi-leg routes. The extra flute layer raises stacking strength at the same footprint, which matters most at the bottom of a pallet where the load sits on the carton rather than beside it. Board grade, flute combination, and closure style are matched to the actual carried weight and the handling the parcel will see, and the print face stays available for brand or handling marks. Longest edge from under 25 cm to over 60 cm, MOQ from 50 on printed runs, one DDP-inclusive quote to the US, EU, UK, and AU.

Audit checklist
Ask to see the double wall in cross-section — the second liner is the whole point and is invisible once the box is closed.
