Common questions
What is ECT-32 and why does it matter for my operation?
ECT (Edge Crush Test) 32 measures single-wall corrugated strength, 32 pounds of force per linear inch before collapse. This rating handles standard ground shipping, moderate stacking, and typical warehouse abuse, making it the industry standard for high-volume B2B shippers balancing cost and durability.
Can I stack these boxes safely in the warehouse?
Yes. ECT-32 kraft supports vertical stacking under normal warehouse conditions. Actual stacking height depends on box fill weight, humidity, and storage duration. Typical 40-50 lb products can safely stack 4-6 boxes high without compression issues.
How many 18x16x12 boxes fit on a standard pallet?
Approximately 120-140 assembled boxes per pallet (48x40"), or 500-600 flat boxes. Exact count varies by arrangement and pallet type. Bulk flat shipping reduces freight cost per box by 40-60% versus assembled inventory.
Are these boxes certified recyclable and eco-compliant?
Yes. These kraft corrugated boxes are 100% recyclable and made from sustainable materials. They meet standard curbside recycling requirements and support corporate sustainability commitments with zero compliance risk.
