Cardboard is a generic term for heavy paper-based products. Their construction can range from a thick paper known as paperboard to corrugated fiberboard, made of multiple plies of material. Natural cardboards can range from grey to light brown in color, depending on the specific product; dyes, pigments, printing, and coatings are available.
The word cardboard has general use in English and French,[1][2] but the term is deprecated in commerce and industry as not adequately defining a specific product.[3] Material producers, container manufacturers,[4] packaging engineers,[5] and standards organizations,[6] use more specific terminology.
