Common questions
What is ECT-32 and why does it matter for my shipping operation?
ECT-32 (Edge Crush Test rating of 32 lbs/inch) indicates the carton's stacking strength and durability. This mid-tier rating is ideal for shallow boxes with lighter to medium-weight contents, balancing protection and cost efficiency. It supports safe stacking without overengineering for products under 20 lbs.
How much storage space do flat cartons actually save?
Flat cartons reduce storage footprint by approximately 90% compared to pre-assembled boxes. A bundle of 25 flat cartons occupies roughly 2 - 3 cubic feet of shelf space versus 25 - 30 cubic feet for assembled inventory, translating to lower warehouse rent and faster order fulfillment.
Is the 6-inch depth suitable for my product category?
The 6-inch depth is optimized for shallow items: apparel stacks, paperback books, framed artwork, mirrors, and clothing. If your average product depth exceeds 5 inches or requires significant padding, consider a deeper carton option to avoid overstuffing and reduce burst risk during transit.
What's the minimum order quantity and lead time?
This SKU ships in bundles of 25 cartons. Most orders process within 1 - 3 business days. For volume pricing on larger quantities (500+), contact our account team to lock in freight efficiency and annual contract discounts.
