A flat cardboard sheet is a flat, single piece of cardboard that is commonly used in packaging, arts and crafts, and various other applications. These sheets are typically made from corrugated cardboard (which has a fluted inner layer between two flat outer layers) or solid cardboard (which is a single, thicker layer). The primary function of flat cardboard sheets is to provide a sturdy, flat surface for protection, support, and construction.
