Common questions
What does ECT-32 mean and why does it matter for my shipping operation?
ECT (Edge Crush Test) 32 indicates the corrugated can withstand 32 pounds of crushing force per linear inch of edge. This single-wall rating is ideal for lightweight to medium-weight items and standard warehouse stacking conditions, sufficient for most tall merchandise without paying for over-engineered double-wall material.
How do these tall boxes compare to mailing tubes for cost and protection?
4x4x28" corrugated boxes cost 40-60% less per unit than cardboard mailing tubes while providing crush resistance and stacking capability. They also stack more efficiently in trucks and warehouses, reducing overall freight spend per shipment.
Can these boxes be used for oversized items, and what's the maximum recommended weight?
These boxes work best for items under 15-20 lbs in standard warehouse conditions. For heavier loads, ECT-42 or double-wall construction is recommended. Weight capacity depends on item fragility, packing method, and stacking height.
Why buy in bundles of 25, and what bulk discount tiers are available?
Bundles of 25 optimize pallet utilization and reduce per-unit cost through bulk purchasing. Most B2B buyers benefit from case quantities ranging 100-500+ units. Contact our sales team for volume pricing and customized subscription programs for recurring shipment needs.
