Dordan was founded in 1962 by Vivian and Edwin Slavin in Chicago, IL. The company began as a contract packager, specializing in skin packaging and small-batch vacuum forming.

In 1974, Edwin’s son, Daniel Slavin, took over as President. Under Daniel’s leadership, Dordan began transitioning into high-volume plastic thermoforming, embracing new technologies including CAM/CNC tooling, microprocessor-controlled thermoformers, and an early focus on engineering-driven design.
Dordan relocated from Chicago to a 50,000 sq. ft. facility in Woodstock, Illinois in 1994.
This expansion enabled: Investment in advanced thermoforming equipment, the development of in-house tooling and engineering departments, and greater production capacity for custom clamshells, blisters, and trays.
In 2013, Dordan achieved ISO 9001:2008 certification, which was updated to ISO 9001:2015 in 2017. This milestone validated Dordan’s dedication to quality management across the design, manufacture, and distribution of custom thermoformed packaging.
Dordan completed the construction of its ISO Class 8 cleanroom in 2019.
This cleanroom supports the production of:
Medical device trays and blisters

In 2024, Dordan achieved ISO 13485:2016 certification for the design, manufacture, and distribution of thermoformed medical packaging. This certification confirms Dordan’s commitment to regulatory compliance and quality control for medical packaging applications.
Continuing the legacy, Julian Slavin—son of General Manager Aric Slavin and grandson of President & CEO Daniel Slavin—joined the company in 2024, marking the fourth generation of family leadership. His arrival ensures Dordan’s future as a family-owned thermoforming company committed to excellence and innovation.
