Robert Gair invented the modern cardboard box in the 1870s in Brooklyn. His accident with a metal ruler led to the creation of the prefabricated box industry by cutting and creasing paper simultaneously.
The first commercial paperboard box appeared in England in 1817. It was credited to the firm M. Treverton & Son and marked an early use of paper-based containers beyond simple storage.
Paperboard is generally thicker than 0.25 mm or 10 points and has a basis weight above 224 g/m2. This specific thickness allows for the vibrant printing and structural integrity needed for consumer goods.
A cardboard box toy house resembling a log cabin was added to the National Toy Hall of Fame in the United States in 2005. It was housed at the Strong National Museum of Play in Rochester, New York.
British stuntman Gary Connery landed on a high crushable runway built with thousands of cardboard boxes in 2012. The mass and viscosity of the enclosed air combined with the limited stiffness of the boxes helped absorb the energy of the fall.
