Dordan has evolved from a small Chicago-based packaging supplier into a nationally recognized manufacturer of high quality medical packaging, clamshells, blisters, and dunnage trays.
Today, Dordan is an ISO 9001:2015 and ISO 13485:2016 certified thermoform packaging supplier, equipped with in house design, tooling, thermoforming, and cleanroom manufacturing of medical packaging. We provide packaging to a wide range of industries, including the medical, automotive, electronic, consumer, and industrial markets.
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 thermoforming and tooling equipment and technology, along with engineering capabilities.

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. The cleanroom is a controlled environment where particulate and bioburden agents are minimized to allow for the production of packaging intended for sterile medical devices. 
Cleanroom-produced packaging types include:
Medical Device Trays & Blisters: Secure, protect, and keep sterile critical medical devices with cleanroom-produced medical trays and blisters
Surgical & Procedural Kits: Facilitate operational workflow and maintain device cleanliness and safety
Medical Clamshells: Protect and display medical products and components inside or out of a Tyvek pouch.
Medical Handling Trays: Organize and protect medical components during shipping and assembly

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. Dordan's quality management system is the foundation of its design, tooling, manufacturing, and cleanroom thermoforming processes and procedures. By supporting controlled systems, Dordan supplies consistently precise thermoformed packaging.

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.
In 2025, Aydan, Julian's brother, joined Dordan, and in 2026, their other brother, Spencer, joined. There are currently 6 family members spanning the 2nd to the 4th generation that work at Dordan.
Dordan uses risk-based engineering and design for manufacturing principles to develop high performing thermoformed packaging.
