Common questions
What is ECT-32 and why does it matter for my operation?
ECT (Edge Crush Test) measures corrugated strength. ECT-32 means each box withstands 32 lbs of crushing force per linear inch, ideal for stacking 3 - 5 boxes high on pallets without collapse. This rating balances cost savings with reliable protection for mid-weight shipments (5 - 40 lbs per box).
How much warehouse space do I save with flat-ship boxes?
Collapsed corrugated boxes occupy approximately 15% of assembled storage space. A pallet of 500 collapsed boxes equals roughly 10 pallets of assembled inventory, reducing storage overhead and enabling faster reordering cycles.
Can I use 28x20x20 boxes for stacking on pallets?
Yes. ECT-32 single-wall supports 3 - 4 boxes stacked vertically when properly loaded (distribute weight evenly across the box bottom). For heavier items, limit stacking to 2 layers or upgrade to ECT-40 double-wall. Consult your product weight and dimensions for optimal configurations.
Are these boxes recyclable and does that affect my sustainability claims?
Yes. 100% Kraft corrugated is curbside-recyclable and compostable. Many B2B buyers now require recyclable packaging for ESG compliance. These boxes support your sustainability goals while maintaining competitive pricing compared to premium alternatives.
