Flexpak’s Aurora, Colorado location, formerly known as Katzke Packaging Co., has been providing packaging solutions across Colorado for over 70 years. Katzke was founded in 1948 in Denver, Colorado by Bob and Clarence Katzke. Years later, Clarence turned the business over to his son, Greg Katzke, who ran Katzke for over 30 years before selling to Glenn Suta. Glenn began his career at Katzke in 1984 in sales, and eventually became the vice president. In 2018, Glenn became the full owner of Katzke and continued to grow the business. During this time, Katzke moved into their current facility in Aurora, CO and added a manufacturing portion of the business to further expand their capabilities. Flexpak acquired Katzke Packaging Co. in September of 2023.
