NEWTOWN SQUARE, PENNSYLVANIA, January 6, 2026 – SupplyOne, Inc., a value-added distributor with corrugated converting capabilities, announced today that it has acquired Wertheimer Box, a long-established Chicago-area corrugated packaging provider known for custom shipping boxes, branded packaging, e-commerce mailers, and specialty retail displays.

Founded in 1939 by Ernest Wertheimer, and based in McCook, Illinois, Wertheimer Box has grown into one of the largest independent corrugated packaging providers in the region. Ernest’s son, Doug Wertheimer, became president in 2004, and has expanded the company’s offerings into dedicated e-commerce packaging solutions, on-demand products, and digital printing.

The acquisition of Wertheimer Box expands SupplyOne’s footprint in the important Chicago market and strengthens its ability to deliver high-quality, custom corrugated packaging to customers across North America. By combining Wertheimer Box’s deep expertise in custom corrugated production with SupplyOne’s national scale and diverse packaging portfolio, the company expects to offer clients a broader range of packaging options (including supplies and digital corrugated), faster lead times, and enhanced services.

“By acquiring Wertheimer Box, we are integrating a highly respected and innovative Chicagoland packaging organization whose reputation speaks for itself,” said Todd Renehan, President and CEO of SupplyOne. “Their dedication to superior quality, exceptional customer service, and custom corrugated expertise directly supports our vision of being the preferred packaging partner for small and medium-sized business across the country.”

Doug Wertheimer, President of Wertheimer Box added, “Joining SupplyOne enables us to tap into national resources and logistics, while preserving the close-knit culture and dedicated customer service that our clients know. We’re excited for what this partnership means for our customers and to build on an 85+ year legacy our employees have built in the market.”

Wertheimer Box is SupplyOne’s 46^th acquisition, expanding its national coverage, further strengthening its regional presence, and enhancing its custom packaging capabilities.
