20" x 16" x 16" Heavy Duty Double Wall Cardboard Box

The 20x16x16 inch double wall cardboard box is a large heavy-duty carton designed for moving, storage, shipping and packing heavier or bulky items. With internal dimensions of approximately 508 x 406 x 406mm, it offers generous packing capacity while remaining practical to hand-carry when full and easy to move through standard doorways.

Manufactured from premium quality BC-flute double wall corrugated cardboard, the carton provides improved crush resistance, rigidity and stacking strength compared with standard single wall boxes. It is ideal for household goods, books, files and folders, clothing, kitchenware, small appliances, tools, industrial components, boxed products and multi-item ecommerce orders.

A key benefit of this box is its variable-depth design. Multi-score creases are provided at approximately 10 inches, 13 inches and the full 16-inch height, allowing the carton height to be reduced to suit the contents. This helps achieve a closer fit around products, reduce unnecessary empty space and improve packing efficiency.

This versatile size is widely used by industrial businesses as a stock and dispatch carton, as well as throughout the removals industry for moving, storage and warehouse use. Its practical proportions also make it suitable for courier and general distribution networks.

The carton is supplied flat packed for efficient 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.
