Common questions
What does ECT-32 mean and is it strong enough for my shipments?
ECT (Edge Crush Test) 32 means these boxes withstand 32 pounds per inch of edge crush force. This rating is suitable for single-wall shipments of lightweight to medium-weight items. For heavier products or multiple-box stacking scenarios, verify your total weight does not exceed the box's burst strength of approximately 200 PSI.
Why choose 4x4x72 boxes over mailing tubes for tall items?
Corrugated boxes offer better stackability, uniform storage footprint, customizable interior padding, and lower per-unit cost than tubes. They eliminate the need to maintain separate tube inventory and provide crush resistance when stacked in warehouse or truck environments.
How many items can I stack before risking box collapse?
ECT-32 single wall supports approximately 3-5 boxes stacked vertically without external support, depending on product weight inside. For heavy items or taller stacks, consider double-wall ECT-44 alternatives or use shelf storage to distribute weight.
Are these boxes suitable for outdoor or long-distance freight shipping?
These kraft boxes are designed for standard indoor industrial shipping and storage. For extended outdoor exposure, moisture-prone environments, or overseas freight, upgrade to water-resistant or double-wall ECT-44 corrugated boxes for enhanced protection.
