22 x 18 x 4" Flat Corrugated Boxes

These 22 x 18 x 4 inch corrugated boxes are purpose-built for flat and low-profile shipments where a shallow interior depth is an advantage rather than a limitation. The 4 inch depth reduces void fill requirements and helps control dimensional weight on outbound parcels, making these a practical choice for operations shipping regularly at volume.

The shallow format suits a specific set of products well: framed artwork, apparel, documents, presentation materials, cutting boards, and other rigid or semi-rigid goods that sit flat but don't stack tall. Fulfillment centers, print distributors, and specialty retailers handling these categories can stock these boxes as a dedicated SKU rather than routing flat goods through general-purpose cartons.

Construction is ECT-32 single wall kraft corrugated board, providing reliable stacking strength and puncture resistance for standard parcel environments. Boxes arrive flat-packed in bundles of 25, keeping storage footprint minimal until needed on the packing line. Each box weighs approximately 1.255 lbs, adding minimal tare weight to finished shipments.
