Penn Products

Penn Products is a leading US manufacturer of plastic cases for packaging, medical, first aid, dental and industrial applications. We currently make over 130 stock models of plastic boxes, including a line of ESD-safe boxes for electronics. Many of our cases have options for molded-in compartments and are thus suitable for packaging fasteners or hobby applications. For customizing, our secondary operations include hot stamp imprinting, pad printing, and labeling. We work closely with Promold Plastics, a company under the same ownership and under the same roof. Penn Products traces its history to an independent injection molder that started operations in 1977 but was relocated to its present facility in 2012 and reorganized at that time. In 2020 our line was enhanced by the acquisition of the former DeWitt Plastic product line. And in 2024 we acquired ownership of the famous Everlast® Pulley line - a line that had been "in the family" since 1977 and that we had been quietly manufacturing for years. We are a family-owned business and our parts are made right here in Connecticut USA.
