Corrugated Board is a multi-layer material made by laminating liners (outer and inner papers) with corrugated medium through a corrugating process. Its fluted medium forms a wave-like structure that provides excellent compression strength, cushioning capability, and overall rigidity. Depending on the number of layers, corrugated board can be classified into single-wall, double-wall, and triple-wall types. It is widely used in shipping containers, protective packaging, and display packaging, making it one of the most essential materials in the modern packaging industry.
