Common questions
What does ECT-90 mean, and why does it matter for my operation?
ECT (Edge Crush Test) 90 measures the corrugated material's crushing strength at 90 pounds per linear inch. This rating ensures your boxes withstand stacking pressures, equipment weight, and rough handling in automated fulfillment environments without failure or product damage.
How many of these boxes can I stack safely on a pallet?
Triple wall boxes with ECT-90 rating support 8-10 layers safely on a standard pallet (40+ lbs per box capacity), maximizing pallet cube efficiency and reducing freight costs per unit shipped. Stack weight depends on product weight and pallet configuration.
Will flat-shipping these boxes really save me money?
Yes. Flat boxes reduce freight dimensional weight by 80% compared to pre-assembled alternatives, cutting inbound shipping costs by 35-40%. Plus, flat storage requires 90% less warehouse space, reducing handling labor and inventory carrying costs.
Are these boxes compatible with automated packing equipment?
Yes. The 16x16x16" cube design assembles quickly by hand or automated equipment and integrates directly with conveyor systems and ergonomic packing stations. Kraft exterior resists degradation from equipment friction.
