A Cooperage on the
Mississippi River
“Build it to last. Deliver it on time. Stand behind it for generations.” Six generations of Wunderlichs have kept that promise, from the first barrel to today’s boxes.

YEARS IN
BUSINESS
Born on the Banks of the Mississippi
In 1860, a craftsman named Charles Wunderlich set up shop just a few blocks from the mighty Mississippi River in St. Louis, Missouri. His trade was cooperage — crafting the wooden barrels that fueled commerce along one of America’s great waterways. The tools were simple. The standards were not.
That original location still anchors us today. Our headquarters at 821 Clinton Street sits only a few hundred feet from where Charles first put hammer to stave — and the river is still out there.
What began as a barrel-making trade has become one of the Midwest’s most respected corrugated packaging operations — a sixth-generation, privately held family business with the same founding philosophy intact.
165 Years in the Making
Every era brought new challenges. Every generation answered with investment, ingenuity and commitment.
A Cooperage on the Mississippi
Charles Wunderlich opens the Monroe Cooper Shop steps from the Mississippi River, making wooden barrels for a booming river city. From day one, the work is built to last and delivered on time.
Chas. Wunderlich Cooperage Co. Is Incorporated
On April 13, 1892, Charles Wunderlich, Charles Wunderlich Jr. and Wm. J. Wunderlich incorporate the business. Charles serves as its first president.
Corrugated Enters the Picture
Seventy years in, Wunderlich begins making corrugated boxes alongside its barrels. In 1948, the Wunderlich Fibre Box Manufacturing Company is established.
Full Commitment to Corrugated
The last wooden barrel leaves the shop and the company becomes 100% corrugated. More than a century in, Wunderlich is fully transformed and fully committed.
Growing on Clinton Street
A new manufacturing building rises next to the original, completed in phases through 2008, with new flexo folder-gluers and a specialty gluer. In 2003, Wunderlich introduces the Pop & Go® floral box. In 2009, the City of St. Louis presents the Spirit of St. Louis Award, and Steve Dybus becomes President.
Quality & Safety, Verified
Wunderlich completes its first third-party GMP audit in 2015 and has been audited every year since. The St. Louis Business Journal honors the company with a Family Business Award in 2020, and it earns OSHA SHARP safety certification in 2021.
The Fifth & Sixth Generations
A Tanabe JD BoxR specialty folder-gluer goes live in early 2024, roughly doubling gluing output for POP displays, and the plant moves to the Encore ERP system. In 2026, Steve Dybus retires, Rob Wunderlich becomes President and Steve Dybus Jr. becomes Vice President. That fall, the plant earns a Kiwa ASI cGMP rating of Superior (96%).
Same Name on the Door. Same Standard on Every Box.
