Common questions
What does ECT-90 rating mean for my shipping operation?
ECT-90 (Edge Crush Test) indicates the box withstands 90 lbs of perpendicular force per linear inch before crushing. Triple wall construction delivers stacking strength, allowing deeper warehouse stacks and higher pallet loads, directly reducing per-unit freight costs.
How much warehouse space do flat-shipped boxes save?
Flat-pack bundles reduce storage footprint by up to 85% versus pre-assembled boxes. A single pallet stores 450-500 bundles versus 50-60 assembled boxes, freeing critical warehouse space for inventory and improving fulfillment velocity.
Are these boxes suitable for outdoor or moisture-prone environments?
Kraft corrugated resists surface moisture, but triple wall is not waterproof. For wet environments, consider adding poly liners or polycoat options. These boxes excel in climate-controlled warehouses and protected transport conditions.
What weight capacity can a single 12x12x12" triple wall box handle?
Single-wall rating supports 40-50 lbs per box; stacking capacity depends on total load and pallet configuration. Most operations achieve 4-6 box stacks at 45-50 lbs each, totaling 180-300 lbs per stack with proper pallet support and load distribution.
