13 x 9 x 4" Flat Corrugated Boxes

These 13 x 9 x 4 inch corrugated boxes are built from ECT-32 kraft single wall corrugated board, offering reliable structural integrity in a shallow, flat-profile form factor. The 4 inch depth keeps contents snug without excess void fill, reducing dimensional weight on outbound shipments.

The shallow depth makes these boxes well-matched for apparel, books, framed artwork, electronic accessories, and other flat or thin goods moving through e-commerce fulfillment centers, retail distribution, and light manufacturing environments. Packing line teams benefit from the consistent interior fit that minimizes the need for dunnage on qualifying product types.

Each box weighs approximately 0.41 lbs and ships flat for compact storage on the warehouse floor or pallet. Available in bundles of 25, these boxes are parcel-friendly and sized for straightforward inventory management without overcommitting storage space.
