For heavier shipments or shipments requiring extra safety measures, shop heavy-duty corrugated cardboard boxes in a variety of styles at Packaging HERO®.

When your shipment needs more protection, be sure to use heavy-duty corrugated boxes that resist damage during the transit process. If you’re shipping heavy objects or sensitive devices, these heavy-duty corrugated boxes offer an easy solution to shipping durability. Thicker box walls mean less damage sustained through impact and less risk of the box tearing during transit. These heavy-duty boxes are offered in single-wall,  double-wall, and even triple-wall strengths. You’ll find a wide range of available sizes and designs as well, such as extra-large heavy-duty corrugated boxes and tall heavy-duty boxes.

Durable Corrugated Boxes Construction for Transit

Our heavy-duty corrugated boxes are made of different types of cardboard depending on the wall density. Single-wall cardboard corrugated cartons are manufactured from 44 ECT kraft corrugated. Double-wall shipping boxes are manufactured from 48 ECT, 51 ECT or 71 ECT kraft corrugated. Triple-wall cardboard corrugated cartons are produced from 90 ECT kraft corrugated.

This variation in structure guarantees that you can find the weight limit for your unique shipment. With greater protection and additional stacking strength, these heavy-duty boxes for shipping are 40% stronger than standard cardboard boxes. They’re also excellent for storage, as the stronger exterior of the corrugated box can be stacked upon and will offer more resistance from external factors.
