Common questions
What is ECT-32-B and why does it matter for my shipping operation?
ECT (Edge Crush Test) 32-B corrugated meets industry standards for protective strength while remaining lightweight. This rating ensures reliable stacking performance in warehouse environments and adequate crush resistance for typical small-item shipments, reducing damage claims while keeping dimensional weight charges minimal.
How much assembly time do these mailers require?
Zero assembly time. Each mailer folds together in seconds with no tape, glue, or staples needed. This one-piece fold-and-tuck design reduces fulfillment labor, speeds throughput, and eliminates supply chain friction for high-volume operations.
Can these mailers stack securely during freight transport?
Yes. The double-wall crush-resistant construction on the front and sides provides structural integrity for stacking, ensuring products remain protected even when palletized or nested with other shipments during ground or parcel transport.
Are these boxes suitable for fragile items?
Absolutely. The ECT-32-B double-wall corrugated kraft design is purpose-built for fragile goods including glassware, electronics, and delicate tools. The compact 11/4" depth allows appropriate cushioning material while the rigid structure prevents crushing during typical handling cycles.
