Common questions

What does ECT-32 mean, and why does it matter for my shipping operation?
ECT (Edge Crush Test) measures the corrugated's resistance to crushing under compression. ECT-32 provides reliable stacking strength for standard warehouse conditions, sufficient for most single-weight shipments while maintaining cost efficiency. This rating ensures your packages maintain integrity through multi-handling logistics chains.
Can these 4x4x8 boxes replace my current mailing tubes?
Yes. The tall, narrow profile and end-loading design offer similar vertical protection for rods, poles, and tube-like items, with the added benefit of stackability and lower dimensional weight charges. Many fulfillment directors report 15-20% freight savings when switching from tubes to appropriately-sized cartons.
How many boxes fit on a standard pallet, and what's the stacking limit?
A single flat bundle of 25 boxes occupies minimal space. When assembled and stacked, ECT-32 single-wall supports stacking heights up to 4-5 boxes high under typical warehouse conditions (weight-dependent). Consult with your warehouse manager for application-specific stacking guidance.
Are bulk discounts available for high-volume orders?
Yes. Packrift offers tiered pricing for orders of 50+ bundles. Contact our B2B sales team with your monthly volume requirements for custom quotes and potential volume rebates.
