Common questions
What is the ECT rating and how does it affect stacking performance?
ECT-32 (Edge Crush Test 32 lbs/in) is rated for stacking heights up to 65 inches in a properly palletized configuration. This rating ensures your products remain protected during multi-tier warehouse storage and transit without risk of box failure or product damage.
How many of these boxes fit on a standard 48 x 40" pallet?
Approximately 50 - 60 flat-stacked boxes per layer. A 5-layer stack yields 250 - 300 boxes per pallet, optimizing freight density and reducing cost-per-unit shipping expenses for high-volume buyers.
Can ECT-32 handle temperature and humidity fluctuations during shipping?
Yes. Single wall corrugated is engineered to maintain structural integrity across standard supply chain conditions (40 - 85°F, 20 - 85% RH). For climate-sensitive cargo, upgrade to ECT-44 or add moisture barriers.
Are these boxes customizable with printing or tape options?
These are standard kraft boxes sold unprinted. Packrift offers custom printing, H/5 tape scoring, and die-cut options. Contact our team for bulk order quotes and lead times on branded or specialty variants.
