Corrugated Cardboard; Corrugated cardboard is a product formed by covering the lower and/or upper surfaces of one or more corrugated layer(s) with a flat layer. There are several types of Corrugated Board that serve different purposes. Various wavelengths of corrugated are used in the production of these types. Single Faced Corrugated Cardboard (Corrugated) Single-sided corrugated cardboard (Corrugated) is corrugated cardboard that is formed by covering only one side of a corrugated layer with a flat layer. "Single-Sided" is obtained by gluing paper to one side of the corrugated sheet, and "Corrugated Cardboard" is obtained by gluing paper to both sides. "Double Wave Corrugated Cardboard" and "Three Wave Corrugated Cardboard" are also produced by bonding paper to the surfaces of more than one corrugated at various wavelengths. Single Wave Corrugated Board Single wave corrugated cardboard is a corrugated cardboard formed by covering both surfaces of a corrugated layer with a flat layer. Double Wave Corrugated Board Double-wave corrugated cardboard is a corrugated cardboard that is formed by covering the lower and upper surfaces of the corrugated layers adhered to the lower and upper surfaces of a flat layer with a flat layer. Three Wave Corrugated Board Three-wave corrugated cardboard is a corrugated cardboard that is formed by covering the bottom and top of three corrugated layers, which are adhered to two flat layers between them, with a flat layer.
