Common questions
What does ECT-32 mean, and is it suitable for my shipments?
ECT-32 (Edge Crush Test) indicates the box can withstand 32 pounds of pressure per linear inch when crushed. This is standard strength for light-to-medium weight products, ideal for apparel, electronics, books, and general merchandise. For heavier items, consider ECT-44 or ECT-48 alternatives.
How many boxes can I stack safely with ECT-32 rated material?
ECT-32 single-wall supports typical 3-4 carton stacks in warehouse storage and transit without product damage. Actual stacking height depends on box fill weight and environmental conditions. Always test with your specific product load for optimal safety margins.
Are these boxes compatible with standard automation equipment?
Yes. The 6 x 4 x 4" dimensions fit most conveyor systems and automated case-packing lines used in mid-sized fulfillment operations. Verify with your equipment manufacturer for gating and sensor specifications.
What's the volume discount structure for high-volume orders?
Bundled purchasing of 25 units reduces per-unit cost versus individual box purchases. Contact our account team for tiered pricing on orders exceeding 5,000 units or for regular monthly subscriptions with freight optimization.
