8 x 8 x 5" White Corrugated Mailers

These 8 x 8 x 5 inch white corrugated mailers are built from ECT-32-B single wall corrugated board, delivering crush resistance and structural rigidity in a lightweight format. The one-piece design folds into a fully closed mailer without tape, glue, or staples, reducing pack time and eliminating the need for additional closure supplies at the station.

The folded construction creates double wall reinforcement along the front and side panels — an advantage for fragile, boxed, or irregularly weighted products. E-commerce sellers, subscription box operators, retail distributors, and B2B shippers rely on this format for direct-to-consumer parcels, sample shipments, and small-unit fulfillment where a clean white exterior matters for brand presentation.

Each mailer weighs approximately 0.45 lbs, helping control dimensional weight costs on outbound shipments. ECT-32-B board meets standard parcel transit requirements without adding unnecessary bulk. Bundles contain 50 mailers, and order quantities scale to accommodate both low-volume and high-throughput operations.
