Common questions
What's the stacking weight capacity of these boxes?
Standard corrugated construction supports stacking loads up to 25 - 30 lbs per box when properly assembled and palletized. Exact ECT rating available upon request. Not recommended for heavy machinery or dense items exceeding weight limits.
How much storage space do I save with flat-ship boxes?
Collapsed boxes consume approximately 90% less warehouse space than assembled boxes. A 15-pack occupies roughly the footprint of a large shoebox, allowing you to store hundreds of units in minimal square footage.
Are these boxes suitable for fragile items?
Yes. Corrugated construction provides adequate cushioning and impact protection for most fragile goods. For extra protection, pair with internal padding, bubble wrap, or kraft paper. Custom ECT ratings available for high-value shipments.
What volume discounts apply to larger pack quantities?
The 15-pack format offers per-unit savings vs. single-box purchases. Higher volume packs (50, 100+) and case-lot orders unlock additional tiered pricing. Contact our B2B team for custom quote on annual volume commitments.
