20 x 20 x 6" Flat Corrugated Boxes

These 20 x 20 x 6 inch corrugated boxes combine a broad, square base with a shallow 6 inch depth, making them a purpose-built solution for flat or low-profile products that standard box proportions accommodate poorly. The large 20 x 20 inch footprint reduces the need for void fill while keeping dimensional weight in check on outbound shipments.

E-commerce fulfillment centers, retail distributors, and light manufacturing operations commonly use this box size for items such as framed artwork, tile samples, folded apparel, trays, and shallow packaged goods. The wide base also suits kitting and assembly operations where multiple flat components ship together in a single carton.

Each box is constructed from ECT-32 single wall kraft corrugated board and ships flat to minimize storage space on the receiving dock. Boxes are sold in bundles of 15, allowing buyers to replenish in manageable increments, and the parcel-friendly size means no special freight coordination is needed for routine restocking.
