20 x 12 x 12" Double Wall Boxes

These 20 x 12 x 12 inch double wall corrugated boxes are built from ECT-48 kraft corrugated board, delivering substantially greater puncture resistance, stacking strength, and load-bearing capacity than standard single wall cartons. The double wall construction is the defining feature here — two combined flute layers create a rigid shell that holds up under compression and rough handling throughout transit.

These boxes are a practical choice for heavy manufactured parts, dense retail goods, bottled or canned products, and high-value items that require reliable outer packaging. Industries such as industrial distribution, e-commerce fulfillment, and wholesale retail regularly rely on double wall construction when single wall strength is insufficient for the product weight or transit conditions involved.

Each box ships flat and is sold in bundles of 15, keeping on-site storage compact. At approximately 1.953 lbs, the boxes add meaningful structural protection without excessive weight added to outbound shipments. Parcel-friendly sizing means these can move through standard carrier networks without requiring freight-only arrangements.
