Celebrating over 50 years!
At Seiler Plastics our engineering and manufacturing team are ready to discuss your custom molded polyethylene applications. We manufacture the polyethylene plastic sheet and convert it into a finished product. Polyethylene molds are an excellent alternative compared to metal, because molded plastic parts are less expensive, lighter in weight, have excellent insulating properties, plus much more. In addition, we can manufacture polyethylene plastic sheet in colors and various thicknesses to meet your application requirements.
