Frequently Asked Questions
ECT-32 (Edge Crush Test) indicates 32 pounds of compression strength per linear inch, ideal for single-wall protection in ground and parcel shipping. This rating handles mid-weight items and standard stacking heights, making it suitable for most long-item fulfillment without overspending on heavy-duty 48 ECT material.
The long-side opening aligns with the product's elongated shape, eliminating awkward angled placement and reducing packing time by 20-30% compared to standard boxes. Your team avoids the excess void fill, tape, and labor associated with oversized square boxes.
Yes. At 12 x 4 x 4", these boxes eliminate the void space that larger square boxes create, resulting in lower dimensional weight and billable space, directly reducing per-shipment carrier fees for high-volume operations.
ECT-32 single-wall supports standard stacking in warehouse environments. Empty boxes stack efficiently; loaded capacity depends on product weight and pallet configuration. For high-density stacking, confirm item weight with your logistics team to ensure compliance with pallet weight limits.
