About this item

SKU MLR1 — 4 3/8" × 4 3/8" × 2", ECT-32-B Corrugated, White. Sold as a bundle of 50, shipped from US warehouses.

The 4 3/8 x 4 3/8 x 2" White Corrugated Mailers - ECT-32, 50-Pack is a corrugated mailer for books, catalogs, apparel, subscription kits, samples, documents, and small e-commerce orders. Listed specs include inside dimensions 4 3/8" x 4 3/8" x 2"; white material; ECT-32; bundle of 50. The mailer format works when the product needs a presentation-style carton or compact shipping box instead of a standard RSC case.

Common questions

What does ECT-32-B corrugated rating mean for my operation?
ECT (Edge Crush Test) 32-B provides 32 pounds per inch of edge crush strength, ensuring reliable stacking performance in warehouse environments. This rating delivers professional protection for small parcels without over-engineering, keeping material costs competitive while maintaining durability standards.
How much time do one-piece mailers save vs. traditional boxes?
Fold-and-tuck design eliminates assembly steps, no tape, glue, or staples needed. Operators can prepare mailers in seconds, reducing fulfillment labor by up to 60% compared to RSC (regular slotted container) boxes that require taping and sealing.
Can these mailers stack safely during storage and transport?
Yes. The double-wall corrugated construction on front and sides provides crush resistance rated to ECT-32-B standards. When properly loaded, mailers maintain structural integrity through multi-unit stacking and handle typical freight conditions without compromise.
How do these mailers affect shipping costs?
The lightweight profile and compact 4 3/8" x 4 3/8" x 2" footprint reduce dimensional weight charges on parcel carriers (UPS, FedEx, USPS). Combined with the zero-assembly design, total cost-per-shipment typically decreases 15-25% compared to heavier corrugated alternatives.
