Common questions
What does ECT-32 mean, and why does it matter for my shipping needs?
ECT (Edge Crush Test) 32 indicates the corrugated can withstand 32 pounds of force per linear inch before crushing. This single-wall construction is ideal for lightweight-to-medium-weight products, offering a cost-effective balance of protection and material efficiency for standard distribution channels.
How does the long-side opening improve packing efficiency?
The 40" opening runs along the length of the box, allowing packers to load items lengthwise without awkward angles or excessive handling. This design reduces packing time by 20-30% compared to standard boxes and minimizes product damage from improper placement.
What's the dimensional weight impact compared to standard boxes?
The 40 x 12 x 12" format optimizes length-to-width ratio for long items, reducing billable dimensional weight on LTL and parcel carriers. For wine bottles or carpet rolls, you'll typically see 15-25% savings in freight costs versus oversized square boxes.
Can these boxes be stacked safely in a warehouse or truck?
Yes. ECT-32 single-wall corrugated supports standard stacking in warehouses and vehicles. Maximum stack height depends on product weight and environmental conditions, but these boxes typically support 4-6 boxes high when loaded with medium-weight goods.
