PDI Plastics started out in 1978 as Polyhedron Designs in Helotes, Texas near San Antonio. The original business specialized in designing and manufacturing displays for retail optical stores. This included thermoforming trays and display components, as well as furniture manufacturing.

In the mid 1990's the company started to focus on making custom plastic components for other manufacturers. The design and manufacture of optical store furniture was discontinued circa 2002.

In 2009 the company was acquired by Christopher Manufacturing LLC and renamed PDI Plastics. At the end of 2009 the company was relocated from Helotes to a new, purpose built building in Mount Pleasant, Texas, about 100 miles east of Dallas on Interstate 30.
