Cardboard boxes, in general, are made from corrugated cardboard, which consists of three layers: an inner and outer layer of flat paperboard with a wavy, crinkled layer in between. The crinkled middle layer provides strength and durability, while the outer layers provide a smooth surface for printing or labeling. Black cardboard boxes are simply those made from this type of cardboard but are coated or dyed black, offering a stylish alternative to the usual brown or white cardboard.

The process of creating black cardboard involves using dark-colored dyes or coatings that turn the typically neutral cardboard into a rich, dark hue. The material is often thicker or more robust than standard cardboard, offering added protection for delicate contents. This variation in the production process makes black cardboard boxes distinctive, combining both form and function to create an aesthetically pleasing yet highly durable product.
