Cardboard

Cardboard is a stiff, thick sheet material made from paper pulp, used chiefly for packaging, containers, and craft projects.

Papermaking: Papermaking is the industrial process of forming sheets from a suspension of fibers in water. Cardboard begins as pulp formed into thick, layered paper sheets.
Fluting: Fluting is the wavy paper layer formed between the liners of corrugated board. The arches create spacing and resist compression in corrugated cardboard.
Corrugated box: A corrugated box is a container made from corrugated fiberboard. It is the most familiar shipping use of corrugated cardboard.
Plastic packaging: Plastic packaging uses polymer materials to contain, protect, or transport products. It often resists moisture better, while cardboard is fiber-based and readily folded.
Wood pulp: Wood pulp is a fibrous material made by separating cellulose fibers from wood. It supplies the fibers used in most cardboard grades.
Linerboard: Linerboard is the flat paper facing bonded to the fluted medium in corrugated board. Its outer surfaces protect the core and provide stiffness and printable faces.
Folding carton: A folding carton is a box cut and creased from a single paperboard blank. It shows how thinner board becomes retail packaging without a corrugated core.
Plywood: Plywood is an engineered wood panel made by bonding thin wood veneers in alternating grain directions. It is much thicker and more durable, but heavier and less suited to disposable packaging.
Cellulose: Cellulose is a structural carbohydrate that forms the cell walls of plants. Cellulose fibers give paper-based board much of its strength.
Adhesive: An adhesive is a substance that bonds surfaces together. Adhesive holds the flutes to the liners and can join box seams.
