Common questions

What does ECT-32 mean and why does it matter?
ECT-32 (Edge Crush Test) indicates the box can withstand 32 pounds of force per linear inch along the flute direction. This standard-strength rating is ideal for typical warehouse stacking scenarios with 3-4 box heights, balancing durability with cost-efficiency for most B2B shipping applications.
How many boxes can I stack safely with ECT-32 material?
ECT-32 boxes typically support safe stacking of 3-4 box heights under standard warehouse conditions. Actual stacking capacity depends on box contents, storage duration, and environmental factors, consult our load-bearing calculator for your specific application.
Is this better than double-wall corrugated for my needs?
ECT-32 single-wall is ideal for lighter shipments (typically under 15 lbs per box) and high-volume operations where freight efficiency and material cost matter most. Double-wall is recommended only for heavier items, long-distance shipping, or extended warehouse storage requiring maximum crush resistance.
Can I order partial bundles or different quantities?
Standard ordering starts at one bundle of 25 boxes. For larger industrial volumes, volume discounts apply at 500+ boxes. Contact our account team for custom quantity options and bulk pricing tailored to your fulfillment forecast.
