SK Plastic is only as good as our last opportunity to serve you. That fundamental belief drives everything we do—and has since 1985 when Steve Streff founded the company in Monroe, Wisconsin, just southwest of Madison. To this day, SK Plastic continues its legacy of molding lasting customer partnerships. You can see our customer-first approach on display in the positive, can-do attitude of each dedicated employee. At SK Plastic, we operate like a family, looking out for each other and the unique needs of each customer.
