Petersen Plastics began serving the Chicago community over 75 years ago as an acrylic jewelry and entrapment company. 3 generations later, we are Chicago’s premier plastics shop. Our primary products include ADA architectural signage and wayfinding signage and logos. Our sign department stands out in both quality and delivery speed. We also have a robust custom fabrication department for virtually any fabricated plastic needs. Lastly, we are a materials distribution hub for the city specializing in acrylic, or plexiglass, and polycarbonate.
