what kind of cardboard is used for cereal boxes
Cardboard The term has been used since at least 1848, when Anne Brontë mentioned it in her novel, The Tenant of Wildfell Hall.[7] The Kellogg brothers first used paperboard cartons to hold their flaked corn cereal, and later, when they began marketing it to the general public, a heat-sealed bag of wax paper was wrapped around the outside of the box and printed with their brand name. This development marked the origin of the cereal box, though in modern times the sealed bag is plastic and is kept inside the box. The Kieckhefer Container Company, run by John W. Kieckhefer, was another early American packaging industry pioneer. It excelled in the use of fibre shipping containers, particularly the paper milk carton.
