Common questions
What does ECT-32 mean, and why does it matter for my operation?
ECT (Edge Crush Test) -32 indicates the corrugated can withstand 32 pounds of crushing force per linear inch. This rating supports reliable stacking in warehouses without crushing, making it suitable for mid-weight items. It balances durability with cost efficiency, stronger than ECT-23 but more economical than ECT-44.
Can these tall boxes replace mailing tubes, and what are the advantages?
Yes. These 4x4x50" boxes offer stacking performance compared to rigid tubes, occupy less pallet space when flat-packed, and eliminate tube assembly time. They provide a rigid, printable surface ideal for branding while reducing per-unit material costs by 15-25%.
How many boxes fit per pallet, and what freight savings should I expect?
A single pallet holds approximately 60 bundles (1,500 flat boxes), with a footprint under 48x40". Flat-packed dimensions reduce LTL freight class ratings, typically saving 20-30% on shipping costs versus pre-assembled alternatives and maximizing warehouse density.
Are these boxes strong enough for stacking during storage?
ECT-32 single-wall corrugated supports stacking heights of 4-5 boxes high when properly loaded with appropriate weight distribution. For heavier loads or higher stacks, ECT-44 is recommended. Always confirm load weight and stack height match your specific application requirements.
