Established in 1991, Polywin Corporation has grown from a visionary start-up into a global leader in the plastics industry. As a family-owned business, we were among the first to bridge the gap between US domestic resources and the emerging manufacturing markets of Asia.
With our headquarters and warehouse in Rancho Dominguez, California, and strategic hubs in China, Thailand, and Malaysia, we provide a seamless network for both domestic supply and international trade.
Today, we continue to build on that 30-year foundation, combining our deep roots in the plastics market with a commitment to long-term, stable partnerships.
Headquarters & Warehouse
Polywin has its humble beginnings in Monterey Park in 1991 as a pioneer in the US-Asia plastics trade. As our business grew, we expanded into our current 100,000 sq. ft. facility in Rancho Dominguez in 2010.
Today, our warehouse serves as our primary logistics hub, supporting both local scrap recovery and international distribution.
