Mitsubishi resin develops functional films with high barrier to water vapor
Mitsubishi resin recently released a water vapor transmission rate of 10-4g /(M2 in ·d) , There is a transparent gas barrier with high barrier property'X-BARRIER”. The film has barrier property to various gases such as oxygen and carbon dioxide. According to the user's requirements, materials with heat resistance, high temperature and humidity resistance, weather resistance and bending resistance can be customized. At present, the evaluation sample has been started and officially listed on July 1. In addition to flexible organic EL displays and organic solar cells, the product is also expected to be applied to cutting-edge medical and pharmaceutical packaging materials.
New Product of Mitsubishi resin'X-BARRIER”And the original product' TECHBARRIER” The water vapor transmission rate and oxygen transmission rate of the existing film.
The film is vacuum evaporated on the substrate (PET, nylon, etc) The surface of the film is coated with a silicon oxide film with a thickness of about 10nm (SiOX, X <2)Made after a thin layer. Fine films were prepared by optimizing the film forming conditions of silicon oxide films. With the company's original' TECHBARRIER” In contrast, the water vapor barrier rate of the new film is increased by 2 ~ 3 orders of magnitude (Figure). This value'Belongs to the highest level in the world'(The company).
applying this product to a new generation of displays such as organic EL panels and electronic paper and organic solar cells can greatly improve the reliability of components. But also can realize flexible panel. In addition, it can also roll-to-roll production, greatly reducing costs.
The company plans to achieve sales of 5 billion yen after 3 years, including cutting-edge medical and pharmaceutical packaging materials. In addition, development will continue in the future, and strive to improve the water vapor barrier by 1 ~ 3 years later ~ 2 orders of magnitude.
