A carton is a type of packaging typically made from paperboard that is suitable for food, pharmaceuticals, hardware, and many other types of products.
Folding cartons are usually combined into a tube at the manufacturer and shipped flat (knocked down) to the packager. Tray styles have a solid bottom and are often shipped as flat blanks and assembled by the packager. Some also are self-erecting. High-speed equipment is available to set up, load, and close the cartons.
