Common questions
What does ECT-32 mean and why does it matter for my operation?
ECT (Edge Crush Test) 32 indicates the box can withstand 32 pounds of crushing force per linear inch, suitable for single-wall applications with moderate stacking loads. For most B2B fulfillment operations, ECT-32 balances durability with cost efficiency, especially when boxes are not stacked excessively high during storage or transit.
How does the 48" length improve my freight efficiency?
The elongated 48" dimension reduces dimensional weight charges on parcel carriers by fitting long items without excess void space. This design also optimizes pallet arrangements, fewer boxes ship the same volume, lowering per-unit freight costs and improving warehouse throughput for high-velocity SKUs.
Can I print my company logo and shipping labels on these kraft boxes?
Yes. The kraft corrugated surface accepts flexographic printing, digital printing, and adhesive labels. ECT-32 single-wall material provides excellent printability for branding, barcodes, and compliance information without sacrificing structural integrity.
What's the typical stacking capacity for a pallet of these boxes?
ECT-32 single-wall boxes typically support 4-5 pallet layers when loaded uniformly and stored under standard warehouse conditions (dry environment, stable temperature). Always test stack height based on your specific product weight and storage duration to ensure compliance with your facility's safety protocols.
