Common questions
What ECT rating does this box have and what can it support?
ECT-32 means the box withstands 32 pounds of edge crush test pressure, making it suitable for lightweight to moderately weighted items. The 3-inch depth limits stacking height but optimizes load efficiency for shallow products and reduces wasted box space.
How many of these boxes fit on a standard pallet?
When flat-packed, approximately 80-100 bundles (2,000-2,500 boxes) fit on a standard 48 x 40-inch pallet depending on stack height, maximizing warehouse utilization and minimizing freight per unit.
Can I use these for heavier items like tools or electronics?
ECT-32 single-wall is designed for lightweight goods. For heavier items, consider ECT-44 or double-wall options. The shallow 3-inch depth is best suited for flat, compact products rather than dense or bulky merchandise.
Are these boxes eco-friendly?
Yes, these kraft corrugated boxes are 100% recyclable and made from renewable kraft paper. They meet standard sustainability requirements for environmentally conscious shipping operations and reduce your carbon footprint.
