With years of thermoforming know-how, we can help you choose the best materials, process and timelines you need to make your product high-quality and profitable.
We don’t do widgets. There are a lot of companies in the world that crank out millions of widgets, without understanding the product or its applications. From top to bottom, our staff understands what your needs are, and it’s our goal to meet them.
The Darby family started GPI in Danville, Illinois, more than 30 years ago.
Today, three generations are involved in the day-to-day operations. Proud to be an American manufacturer, GPI employs more than 75 people.
GPI is committed to green solutions. From replacing mercury-vapor lighting to reducing and recycling plastic waste, we take big and small steps towards reducing our environmental footprint.
These kinds of efforts have reduced our energy consumption and overhead costs, too. We are happy to pass those savings on to you!
