These 18 x 12 x 4 inch white corrugated mailers are built from ECT-32-B single wall corrugated board and fold into a finished enclosure without tape, glue, or staples. The one-piece self-locking design creates double wall thickness along the front and sides when assembled, delivering added compression resistance that standard single-layer mailers do not provide.
The clean white exterior makes these mailers well suited for customer-facing e-commerce shipments, retail distribution, and subscription box fulfillment. Apparel, printed goods, framed artwork, and flat media all fit comfortably within the interior footprint — any product category where a rigid, presentable enclosure reduces damage claims and return rates.
Each mailer weighs approximately 0.85 lbs, keeping per-shipment weight manageable across volume orders. Sold in bundles of 50 and ships via parcel carrier.
