Multi-depth boxes can be cut to precise depths to fit packaging needs. These boxes are available as heavy-duty boxes and regular boxes. Heavy-duty multi depth boxes are used in warehouses tight on space, and ship a variety of sized items. These boxes are scored at multiple depths to provide the exact for every product without taking up warehouse space. Simply cut down until your box is the right size. The heavy-duty boxes are 40% stronger than the regular 200# corrugated material.
