WHO WE ARE
Since 1860, Wunderlich Fibre Box Company has been a significant player in the Saint Louis packaging industry, evolving from a maker of wooden barrels for riverboat trade to a leader in innovative packaging solutions. Now in its sixth generation, the company has adapted to changing demands by investing in advanced technologies and pioneering printing techniques. Today, Wunderlich continues to innovate with versatile and precise machinery, offering vibrant and striking packaging designs that enhance product shelf presence, while maintaining its commitment to exceeding expectations and timely service.
“From the battlefield to the business world, one principle remains constant: success depends on having reliable partners you can trust to execute. We started Triumph Systems in a garage ten years ago, and today our products have national retail distribution. Glen and the team at Wunderlich have been an important part of that journey, consistently delivering the quality, responsiveness, and dependability that growing businesses need to succeed.”

Custom Corrugated Packaging, Designed and Made in St. Louis
Wunderlich designs and manufactures custom corrugated boxes, POP displays, and protective packaging for brands across the U.S. Structural design, prepress, and printing — flexo, top-sheet litho, and digital — all come from one source.
Custom Corrugated Boxes
Printed and plain shipping boxes in single- and double-wall board: regular slotted (RSC), full overlap (FOL), half slotted (HSC), and die-cut mailers and trays. Most orders ship in 5–10 business days.
Structural Packaging Design
Our in-house designers build to your product, not the nearest stock size. Structural samples are free (simple styles in 2–3 business days), and nothing prints until you approve a PDF proof.
Shipping Boxes & Supplies
Everyday RSC, FOL, and HSC shippers, pads, and sheets in your exact dimensions. These styles run on our folder-gluers without a cutting die, so short runs and reorders stay affordable.
POP Displays & Custom Structures
Floor displays, counter displays, and display-ready shippers that sell at retail. Multi-color flexo printing and die-cutting run in one pass on our rotary die cutter for sharp registration.
Protective Inserts & Partitions
Corrugated inserts, partitions, pads, and die-cut cradles that hold product tight. They cut damage in transit and replace foam and plastic dunnage with curbside-recyclable fiber.

Sustainable Corrugated Packaging.
No Asterisks.
Corrugated is the most recycled packaging material in the U.S. About 91% is recovered and repulped into new board (AF&PA, 2021). As an independent converter, we source corrugated sheet from established U.S. mills and turn it into right-sized boxes and displays here in St. Louis. We print with water-based inks, design out excess board and void fill, and bale our plant trim back into the fiber stream.
Need SFI or FSC certified fiber? Tell us upfront. We’ll source it and document it.
