Heavy Duty Cube Corrugated Boxes, 12" x 12" x 12", 275 lb. Test
When ordinary boxes aren't strong enough for the job, these Heavy-Duty Cube Cartons step in. They are built to a 275-pound test strength for shippers who need serious load-bearing capacity in a standard, easy-to-stack cube format.
Rated for Demanding Loads
275 lb. Test Strength
This box carries a 275-pound bursting test rating, placing it well above standard-duty cartons in terms of compression and puncture resistance. That added strength translates directly into fewer damaged shipments, whether the box is holding dense, heavy contents or simply enduring the weight of other boxes stacked on top during transport and warehousing.
Engineered for High-Stress Environments
The heavier corrugated walls are designed to hold their shape under sustained pressure, resisting the sagging, bulging, or collapse that lighter-duty boxes can experience when pushed past their limits. This makes the box a dependable choice for freight shipping, industrial packaging, and long-haul transport where boxes face rougher handling from start to finish.
A True Cube for Maximum Load Efficiency
Balanced 12" x 12" x 12" Dimensions
The equal-sided cube shape distributes weight evenly across all surfaces, reducing stress concentration on any single wall or corner. This balanced geometry also makes the box easier to stack securely and predictably, whether on a pallet, in a truck, or on a warehouse shelf.
Efficient Use of Space
The cube format maximizes usable interior volume relative to its footprint, helping reduce the number of boxes needed for bulkier or irregularly shaped loads while keeping pallet configurations clean and stable.
