MIRWEC Film, Inc. was incorporated in 1988 as a joint venture between Mitsubishi Rayon Company, Ltd. (MRC) and Westinghouse for the purpose of assuring Westinghouse a reasonably priced, high quality source of polypropylene film for Westinghouse's capacitor division.
In 1989 Asea Brown Boveri Ltd. (ABB) acquired MIRWEC shares held by Westinghouse as a part of the purchase of certain Westinghouse facilities and assets. MIRWEC benefited from the advance technology and experience of two leaders in the manufacture and use of high quality capacitor grade film. The joint venture ended in 1992 when MRC acquired the interest held by ABB. In 2002, Yasui Seiki Co., Ltd. acquired the majority interest of MIRWEC Film, Inc. from MRC. We expanded our facility in 2004. Since summer 2004, we have provided precision coating services for a wide variety of industries, using Yasui Seiki's precision coating machines. Due to the increasing volume of coating interests, we extended our facility in 2006 to install a new coating machine, IS-1600. We installed the 2nd film line in 2008.
