Common questions
What does ECT-48 mean and why does it matter?
ECT (Edge Crush Test) 48 means this box withstands 48 lbs of pressure per linear inch of edge. Double wall construction doubles stacking strength, allowing 4-5 boxes high without collapse, critical for high-volume warehouses maximizing pallet density.
How much freight space do I save with flat shipment?
A bundle of 15 flat boxes occupies roughly 2.5 cubic feet versus 30+ cubic feet pre-assembled. You'll reduce inbound shipping costs by 40-50% and free valuable warehouse shelving for inventory.
Is this box suitable for heavy or liquid items?
Yes, ECT-48 double wall is rated for items up to 65 lbs per box. For liquid shipments, use polyethylene liners or bladders inside. The kraft material resists moisture but isn't waterproof without additional protection.
Can I customize or print logos on these boxes?
Absolutely. Packrift offers full-color flexographic and digital printing for orders of 500+ units. Contact sales for custom branding, barcode labels, and rush production options.
