US-based packaging company SupplyOne has acquired compatriot Wertheimer Box, a corrugated packaging provider.

Financial details of the deal were not disclosed.

Headquartered in McCook, Illinois, Wertheimer Box is known for producing custom shipping boxes, branded packaging, e-commerce mailers, and speciality retail displays.

Wertheimer Box president Doug Wertheimer said: “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."

This acquisition extends SupplyOne’s reach in the Chicago area and broadens its capacity to supply custom corrugated packaging across North America.

The integration of Wertheimer Box’s experience in corrugated manufacturing is expected to add to SupplyOne’s existing portfolio and service offerings.

SupplyOne CEO and president Todd Renehan said: “By acquiring Wertheimer Box, we are integrating a highly respected and innovative Chicagoland packaging organisation whose reputation speaks for itself.

“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 businesses across the country.”

Wertheimer Box marks SupplyOne’s 46th acquisition, extending its national coverage and regional capabilities in custom packaging.

In November 2025, SupplyOne expanded its national foothold with the acquisition of Lamb & Associates Packaging, a corrugated packaging manufacturer based in Arkansas.
