About Us

1993 is the year Plastics Unlimited was born in a shed on Terry and Nancy Kieffer’s farm in Preston, Iowa. With a little faith and whole lot of dedication, they grew Plastics Unlimited from that little shed with a single station thermoforming machine to an 80,000 square foot building. Now, four expansions later, we’re still growing and customers have been coming from all over the world in increasing numbers. We focus on cutting edge technology and we like to show our customers new products that could help them out before most other companies even know about them.
