30" x 18" x 12" Extra Large Heavy Duty Double Wall Cardboard Box

The 30x18x12 inch double wall cardboard box is an extra-large heavy-duty carton designed for packing, storage, warehouse dispatch and shipping. With internal dimensions of approximately 762 x 457 x 305mm, its long, wide footprint and relatively low 12-inch height make it particularly suitable for larger or flatter products that need strong protection without excessive carton depth.

Manufactured from premium BC-flute double wall corrugated cardboard, the carton provides excellent rigidity and crush resistance during handling, storage and transit. It is particularly useful for clothing and fashion orders, boxed products, flat-packed goods, household items, components, multiple-item ecommerce orders and larger products requiring a long rectangular carton.

The 30x18x12 size is widely used by ecommerce businesses, fashion retailers, warehouses, manufacturers and fulfilment operations as a practical dispatch and storage carton. Its shallow profile helps make efficient use of storage and packing space while the double wall construction provides additional protection for goods moving through courier and distribution networks.

The carton is supplied flat packed for efficient warehouse storage and is quick to assemble. Fold into shape and securely seal the top and bottom with packaging tape before use. All dimensions shown are internal and listed as length x width x height.
