Inventor of the Corrugated

Sheet Feeder Concept

An entrepreneur and visionary, our founder Richard (Dick) Van Horne Sr. saw the emerging need for cost effective, high-quality corrugated sheets early, during a time when sheets could only be bought from integrated box plants. To the sheet plants at that time, and clearly still today, continuity of supply was critical to their success and growth. They finally had a source of sheets from a supplier who was not a competitor. In the 1980’s, Dick was quick to provide performance packaging that met the newly approved ECT standards. Dick personally took the risk to invest in a building and corrugator to produce exclusively sheets for independent sheet plants in the upper Midwest. Hence, Corrugated Supplies Company was born and today maintains the same vision of serving sheet plants from many manufacturing locations in the US.

Our Leadership Today

John Potocsnak started his corrugated career in 1980 at Traub Box in Cleveland, Ohio, under the leadership and mentorship of David Simon. John started at Traub as plant engineer and worked his way up to VP of Operations. After 8 years at Traub, John went into selling corrugators for Simon Container Machinery. At Simon, John expanded his knowledge, and moved to England where he ran his first sheet feeder for Windrush (a joint venture with Smurfit and MacMillan Bloedel). John spent 4 years in England turning around the Windrush location during England’s worst recession since the 1920’s. 

After England, John moved back to the US and continued his career at CorrRock, a box plant outside of Cincinnati, Ohio. At CorrRock, John and two others developed the Big Mac™ box for McDonalds™, and became the original “MacDaddy.”  Following this, John went back to the sheet feeder world and became GM for BardCorr in Guthrie, KY and Pulaski, TN. John spent the next 3 years working with the teams at both locations creating a positive work culture and developing strong teamwork. 

From BardCorr, John spent the next couple of years as a consultant for JTA (John Tries Anything). Staying sold out kept John busy, but it wasn’t until meeting Rick Van Horne at Corrugated Supplies, that John knew he found his “home.” At the time, CSC was partners with the Jack Schwarz in CeCorr, a sheet feeding venture.  In 1998, CSC sold its interest in CeCorr to Georgia Pacific while keeping its original location in Bedford Park, IL. Over the next 20+ years, John has grown CSC from a single location with two corrugators to 11 corrugators in 8 locations across the country and a 100% recycled medium mill in Alsip, Illinois. While John continues to grow and lead CSC, he has used his success to further his passion for philanthropy.
