Prairie Plastics has focused on custom thermoformed solutions since its founding in 1998. Located in Sun Prairie, Wisconsin, we provide design, prototyping, single- and twin-sheet manufacturing, in addition to CNC trim, assembly, and kitting of parts.
Early on, Prairie Plastics established a name for itself by providing competitive pricing and lead times, as well as quality manufacturing. As the company matured, Prairie Plastics developed the capability and capacity to provide service to both high-volume and smaller-volume customers.
Over the years, our service and expertise have earned us loyal customers, choosing us over larger thermoformers for the personal experience we are able to offer. A mindset that continues to this day.
This approach also helps us continue to add value to our customers’ experience. More specifically, it means working with a thermoforming company that never leaves you asking, “what is the status of my order?”
From 3-D designs to prototypes for innovative solutions, Prairie Plastics offers our customers a full-service experience based on integrity and customer focus, as well as a deep commitment to quality products.

THERMOFORMING PLASTIC RECYCLING
Thermoforming plastic recycling is a process of breaking down and reusing plastic products and materials that have already been used. This process helps to reduce landfill waste and conserve natural resources by transforming the plastic into new products. The process involves melting the plastic and then reforming it into a usable shape. It is a cost effective, environmentally friendly way to reuse materials that would otherwise be discarded. By recycling plastic through thermoforming, companies can help to reduce their carbon footprint and create products that are more sustainable.
