Common questions
What does ECT-32 mean and why does it matter?
ECT (Edge Crush Test) measures corrugated board strength in pounds per linear inch. ECT-32 provides reliable protection for medium-weight products without the cost premium of heavier ratings. It's ideal for apparel, books, and framed items that don't require excessive cushioning.
How much space do these boxes save compared to assembled inventory?
Flat boxes reduce storage footprint by up to 95% versus pre-assembled cartons. A pallet of 1,000 flat boxes occupies roughly 4 - 6 cubic feet; the same quantity assembled requires 40+ cubic feet, directly impacting warehouse rent and inventory management efficiency.
Can these boxes handle stacking during storage and transit?
Yes. ECT-32 corrugated supports safe stacking up to 6 - 8 boxes high when properly loaded (weight and pallet configuration dependent). The shallow 3" depth also reduces overall stack height, improving pallet stability and carrier utilization.
Are these boxes suitable for hazmat or fragile items?
These boxes work well for padded apparel and books but are not rated for hazmat. For fragile items like mirrors and artwork, ECT-32 provides adequate base protection; add internal void fill, bubble wrap, or foam to meet carrier requirements and customer expectations.
