Common questions
What does ECT-44 rating mean, and how does it affect stacking performance?
ECT-44 (Edge Crush Test) measures the amount of force per inch of box edge required to crush the corrugated material, in this case, 44 pounds per linear inch. This rating allows safe vertical stacking of up to 6 boxes without risk of compression failure, maximizing pallet density while protecting contents during storage and transit.
How much stronger is this box compared to standard shipping containers?
These heavy-duty boxes are 40% stronger than standard single wall corrugated, delivering edge crush strength and burst resistance. This increased durability reduces damage claims, decreases product loss, and lowers total cost of ownership across your fulfillment operations.
Can I safely stack multiple pallets of these boxes on top of each other?
Yes. With ECT-44 rating and heavy-duty kraft construction, these boxes safely support stacking up to 6 layers high when properly distributed. This enables efficient use of vertical warehouse space and increases your pallet density for improved freight economics.
Are these boxes environmentally compliant and recyclable?
Completely. These kraft corrugated boxes are 100% recyclable and compostable, supporting your sustainability commitments and meeting ESG requirements for eco-conscious customers and retailers.
