Cardboard is a generic term for heavy paper-based products. The construction can range from a thick paper known as paperboard to corrugated fiberboard which is 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 term "cardboard" has general use in English and French,[1][2] but the term cardboard 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.
