This invention provides reinforced paperboard and articles made from such reinforced paperboard, wherein the paperboard and articles have improved strength properties. The reinforced paperboard is formed by impregnating one side of the paperboard with a liquid reinforcing composition, such as a latex material. The impregnation is continued until the reinforcing composition penetrates to a depth of from about 5 to about 25 percent of the paperboard tickness. |
