Johnson Plastics, headquartered in Minneapolis, Minnesota, has been a supplier to the engraving and sign making industry since 1970. The Johnson family began the business selling plastic and magnetic products used by sign shops to produce vacuum formed signs. The business is built on the belief that personal service and a strong customer focus are as important to the business as the products that are sold.

In 2002 Johnson Plastics entered the sublimation arena. Partnering with Unisub, Sawgrass, Vapor Apparel and several other vendors the company has become a dominant force in sublimation.

Still family owned, to adequately serve its national customer base Johnson Plastics added additional branch offices and warehouses. Concord, California (1975), Dallas, Texas (1986), Troy, Ohio (1987) - moved to Columbus, Ohio (1990), Atlanta, Georgia (1996), Algonquin, Illinois (1996), Phoenix, Arizona (2000) and Winston-Salem, North Carolina (2004).
