These 6 x 4 x 2 inch kraft corrugated mailers are built from ECT-32-B single wall corrugated board and fold into a finished mailer with reinforced double wall construction on the front and sides — no tape, glue, or staples required at the point of pack.

The flat-pack format suits e-commerce fulfillment centers, retail distribution operations, and manufacturing environments where pack station speed and floor space both carry weight. At approximately 0.127 lbs, the lightweight build helps control postage costs on high-volume outbound shipments of small, compact goods.

Each bundle contains 50 mailers. The parcel-friendly format supports flexible order quantities, and the flat-storage profile means inventory can be staged without dedicating significant shelf or floor space to pre-assembled packaging.
