These 12 x 9 x 4 inch kraft corrugated mailers are built from ECT-32-B single wall corrugated board and fold into a double walled configuration along the front and sides. The one-piece construction locks closed without tape, glue, or staples, reducing pack-out steps and eliminating the need for secondary closure materials at the line.

The flat-fold design makes these mailers practical for high-density storage environments where shelf and floor space is limited. At approximately 0.86 lbs, the lightweight profile helps keep parcel weights manageable — making these a natural fit for e-commerce fulfillment operations, retail distribution centers, and direct-to-consumer shipment workflows.

Each mailer presents a clean kraft finish that conveys a professional appearance without additional wrapping or branding materials. Bundles of 50 provide stocking sized for consistent replenishment in operations running predictable SKU volumes, and the parcel-friendly format supports standard carrier fulfillment without special handling requirements.
