Common questions

What does ECT-32 mean and how does it perform?
ECT-32 refers to Edge Crush Test rating of 32 pounds per linear inch, standard strength for single-wall corrugated. This supports typical mid-weight products and reliable stacking in warehouse environments without the cost premium of heavier ECT ratings. Suitable for most non-hazmat shipments.
How many boxes fit on a standard pallet?
Approximately 60-70 assembled boxes per standard 48x40" pallet, depending on stacking height and cube optimization. Flat bundles reduce inbound freight costs significantly, contact our team for detailed pallet configurations for your volume.
Are these boxes ISTA compliant or suitable for hazardous materials?
These ECT-32 single-wall boxes are suitable for standard commercial shipments. For hazmat or specialty certifications (ISTA 3A/3B, UN-rated, etc.), please consult our packaging specialists or request our certified product line.
Can I order in larger volumes with custom printing?
Yes. Bulk orders of 500+ boxes qualify for volume pricing and custom printing options. Contact our B2B sales team at [contact] to discuss minimum order quantities, lead times, and branding solutions tailored to your fulfillment needs.
