Common questions
What does ECT-32-B corrugated mean and how does it perform?
ECT (Edge Crush Test) 32-B indicates this corrugated material can withstand 32 pounds per inch of crushing force, ideal for small parcel shipping. The B-flute construction provides excellent crush resistance while remaining lightweight, reducing dimensional weight charges and keeping postage costs competitive.
Do these mailers require tape, glue, or fasteners?
No. The one-piece fold-and-tuck design eliminates the need for tape, glue, or staples. Mailers fold together in seconds, reducing labor time and material costs while speeding up your fulfillment process.
How does this box size impact shipping costs and pallet density?
The 4x4x4" cube format maximizes pallet stackability, allowing you to fit more units per pallet and reduce freight spend per unit. Lightweight ECT-32-B construction minimizes dimensional weight penalties, delivering significant cost savings on volume shipments.
Is this mailer suitable for fragile items?
Yes. The double-wall corrugated protection on the front and sides provides crush resistance, making it ideal for protecting small fragile items like electronics, glass vials, and delicate products during transit and handling.
