Electron beams are beams obtained by applying high voltage to electrons, and they are utilized in the production of high-performance food packaging and the improvement of semiconductor properties, contributing to the realization of SDGs through the extension of food shelf life and energy conservation. ■ Reduction of VOC emissions through EB curing of printing and coating films EB-curable resins and paints can be made VOC-free. Additionally, they cure instantly upon irradiation, reducing CO2 emissions during the drying process compared to thermal drying methods. ■ Contribution to energy conservation through the improvement of power semiconductor properties By generating lattice defects with EB, it is possible to control semiconductor properties. They are used in switching devices such as air conditioners, contributing to energy savings. ■ Contribution to the extension of food preservation periods with high-performance food packaging materials Crosslinking technology using EB is also utilized in the production of food packaging films. High-performance food packaging materials contribute to the extension of food preservation periods. ■ Enhancement of plant-based plastics Plant-derived polylactic acid has faced challenges due to low heat resistance and transparency. Modification through EB crosslinking improves the heat resistance of polylactic acid while maintaining transparency, expanding its applications as an alternative to petroleum-based plastics.
