18 x 12 x 4" Flat Corrugated Boxes

These 18 x 12 x 4 inch corrugated boxes are purpose-built for low-profile shipments where a shallow-depth carton is needed. Manufactured from ECT-32 single wall kraft corrugated board, they deliver reliable compression strength and puncture resistance suited to standard parcel transit conditions.

The 4 inch depth makes these boxes a practical fit for e-commerce retailers, subscription box operations, and wholesale distributors shipping apparel, books, flat-packed goods, framed artwork, or similarly thin products. Their footprint integrates efficiently into conveyor systems and standard pallet configurations, reducing void fill requirements and keeping dimensional weight low.

Each bundle contains 25 boxes shipped flat, minimizing storage footprint at pack stations and enabling efficient staging in high-throughput environments. Each box weighs approximately 0.72 lbs, keeping added tare weight negligible even at high order volumes. The parcel-friendly format supports direct replenishment ordering to warehouse and fulfillment locations.
