Our History
Jim Duddleston, Delkor's founder, was a true entrepreneur who loved designing new packaging machinery. After leaving Land O'Lakes in the late 1950's, Jim launched a company named Ascon Engineering that pioneered the manufacturing of fillers for plastic-coated milk cartons. At that time milk was sold primarily in glass bottles or wax coated paper cartons. After many successful years, Jim's company was acquired by the leading milk-carton filling company at the time, Hercules Corp. Jim headed a division for Hercules until 1973, when we returned to Minneapolis to embark on a new and exciting venture, launching Delkor.
