Film-Related
Technical Departments

Our Film-Related Technical Departments oversee the development of new products and processes involving high-quality, high-functionality films, including polyester film, polypropylene film, polyphenylene sulfide (PPS) film, aramid film, and polylactic acid film. Collaborative efforts to develop technologies for polymerization, film formation, and processing by our Japanese sites and five overseas sites (in the US, France, China, Korea, and Malaysia) allow us to quickly respond to customer needs, and to market products with outstanding performance, quality, and cost attributes.
By actively promoting exchanges between engineers in Japan and overseas, we are systematically working to enhance and develop our basic technical capabilities.

Advanced Film Technical Dept.

The Advanced Film Technical Dept. is responsible for the development of new products and processes for LUMIRROR® polyester film and ECODEAR® environmentally friendly polylactic acid film. It also handles development of PICASUS® film-a film with a metallic sheen made using multilayer lamination technologies. The Shiga Plant brings together related jobsites involved in research and engineering allowing us to create new products with high added value which integrate basic technologies.

Film Technical Dept. Gifu

The Film Technical Dept. Gifu handles the development of new products and processes involving LUMIRROR® polyester film as well as TORELINA® polyphenylene sulfide (PPS) film, which is produced worldwide solely by Toray. This department develops products for the wide range of applications in which LUMIRROR® is used, including hightransparency films used in flat panel displays and films used on sublimation printer ribbons. TORELINA® has outstanding heat and chemical resistance, and its use is expanding primarily in the insulating materials used in electronic components and automobiles.

Film Technical Dept. Mishima

The Film Technical Dept. Mishima handles the development of new products and processes for LUMIRROR® polyester film as well as MICTRON® aramid film, which is produced worldwide solely by Toray. It also plays a role in supervising the development of polymerization technology used on the raw materials required in the production of LUMIRROR® and MICTRON®. Developed products include films for high-recording-capacity magnetic tape materials and mold releasing films for polarizing plates.

Tsuchiura Plant Technical Sect.

The Tsuchiura Plant Technical Sect. develops capacitor applications and packaging/industrial material applications of TORAYFAN® polypropylene film. Extremely thin films with a thickness of 3µm or less are being used in capacitors for hybrid electric vehicles (HEVs), and Toray is exploiting its technological and quality advantages to retain its top market share.
