Abstract. Electron beam roll-to-roll (R2R) coating of flexible substrate materials is a mature manufacturing technology in use for the production of magnetic tape since the mid 1980’s. However, the increasing demand for transparent «ceramic» barrier coatings from the packaging industry has resulted in the development of a new generation of new electron beam based R2R coating tools to meet both the product quality and productivity requirements of the packaging market. To lower coating costs, tools up to 2.85 m in roll width have been designed and built and are now in high volume production.
