Common questions
What does ECT-32-C corrugated mean, and why does it matter?
ECT-32 refers to Edge Crush Test rating of 32 pounds per linear inch, a measure of stacking and puncture resistance. This 'C' flute designation balances protection with lightweight shipping economics, ideal for e-commerce where dimensional weight fees directly impact margins.
How does multi-depth scoring reduce my shipping costs?
Score lines let you fold to 2", 4", or 6" depths depending on product density. Lighter items use less dimensional space, lowering UPS/FedEx charges. You eliminate oversized packaging waste while maintaining professional cushioning.
Can I use these for high-end brand presentation?
Yes. Kraft corrugated delivers natural, premium aesthetics popular with sustainable-minded brands. The jumbo 2824" size accommodates custom logos, QR codes, and branded inserts without additional packaging layers.
What's the difference between these and regular mailers?
Standard mailers typically max at 129". These 2824" jumbo mailers handle oversized shipments like framed prints, large bundles, and multi-item orders in a single box, eliminating the need for multiple smaller boxes and reducing per-shipment costs.
