Common questions
What does ECT-48 rating mean for my shipping operations?
ECT (Edge Crush Test) 48 indicates the material can withstand 48 pounds of force per linear inch before crushing. Double wall construction at this rating provides stacking strength, allowing safe 4-6 carton stacking in warehouse conditions and protecting contents during rough handling.
How much warehouse space do I save by ordering flat boxes?
Flat cartons reduce storage footprint by 80% compared to pre-assembled boxes. A bundle of 15 flat boxes occupies minimal pallet space, enabling higher inventory turnover and lower storage costs while maintaining quick assembly when needed.
Are these boxes suitable for heavy or fragile items?
Yes. The ECT-48 double wall construction provides excellent crush and puncture resistance, making these boxes ideal for mid-to-heavy items, electronics, glassware, and fragile goods. The robust kraft material minimizes product damage and reduces freight claims.
What volume discounts apply when ordering multiple bundles?
Contact our B2B sales team for volume pricing. Orders of 10+ bundles (150+ boxes) qualify for tiered discounts, and we offer freight consolidation on bulk purchases to maximize your logistics savings.
