Keystone is a privately owned company that was founded circa 1890 by Mr. Jesse S. Keys in the Afton section of Madison, New Jersey. Originally known as The Keys Folding Paper Box Company, the Keystone Folding Box Company was incorporated in 1908 by Mr. Charles A. Chase and Edwin T. English. Keystone moved to Newark, New Jersey in 1910 and later, 1923, built a factory at its current location.
Today this historic company is owned and operated by the Hartman family, who have been directly involved with Keystone for more than 60 years. The very same unwavering philosophies and standards for quality still guide the company today…and will lead Keystone into the future.
