Dart Manufacturing Company was founded in 1937 by William F. Dart, a son of the founder of
Dart National Bank. As a machine shop, it manufactured key rings, steel tape measures, and dog tags for the
Department of Defense. It also created popular toy for kids, called Marble Race. During the 1960s and '70s, Dart expanded to Pennsylvania, Illinois, California, and Texas. It also started making plastic dinnerware and cutlery. In 1981, the company filed a patent for a more user-friendly lid. It was a plastic disc with a press-down tab that allowed customers to drink while the lid was still on. Dart opened a facility in
Plant City, Florida, in 1983, and another in
Lodi, California, in 1984. A facility in
Campbellford, Ontario in Canada was opened in 1985.
Kenneth Dart became president in 1986. In 1996, the company expanded to Mexico, opening a facility in
Atlacumulco. In 2006, Family Business Magazine ranked Dart Container 137th in its listing of family companies, with an estimated $1.1 billion in sales, and 4,950 employees. In 2007, Dart opened a facility in
Tijuana, Mexico. At the time, the company had 7,500 employees and 16 million square feet of plant space worldwide. Dart Container purchased
Solo Cup Company in May 2012 in a deal valued at approximately $1 billion. The iconic Solo red cup was slated to remain under the Solo name. Following the acquisition, Dart consolidated its operations in Canada, forming Dart Canada in 2014. At the time, the subsidiary employed 380 people and had facilities in Toronto and Campbellford, a corporate office in Toronto, and a Mississauga warehouse. By 2013, Dart had 14,000 employees across 45 locations in 12 U.S. states and eight countries, including Canada, the United Kingdom, Mexico, Argentina, and Australia. When Maryland banned the use of foam plastics, Dart closed its distribution centers in
Hampstead and
Havre de Grace. Operations were relocated to
New Castle, Delaware. In February 2020, Dart eliminated 6% of its administrative and sales workforce. During the
COVID-19 pandemic in 2020, Dart produced thousands of plastic
face shields for health care workers. In March 2023, the company announced the closure of its
Tumwater facility in Washington. Its
Urbana, Illinois facility was shut down at the end of the year, affecting 135 jobs. Dart eliminated 250 corporate jobs, including 160 from its Mason headquarters, in September 2024. It closed two plants and eliminated 175 jobs in California the following month in connection to the state's ban on expanded polystyrene. ==Operations==
