Toray recently announced the world's first successful development of a polylactic acid film made from plants. This kind of film has the flexibility and heat resistance originally possessed by polylactic acid, and it also has flexibility that can be rolled up. As an environment-friendly film that can be fully degraded, it is expected to cause strong demand.

Although polylactic acid is regarded as an environmentally friendly material, it has attracted attention. However, in the production method of adding a low molecular liquid plasticizer, there was a great influence due to external changes such as temperature and pressure, transparency, and flexibility. The disadvantage of big changes. However, in the new technology developed by Toray this time, a biodegradable high-performance alloy component that is highly interactive with polylactic acid and has a high mobility unit has been designed. In addition, the high-precision biaxial stretching technology allows the crystals to be regularly arranged to improve the flexibility of the film.

Toray said that the material will be widely used in packaging materials (such as flexible packaging), protective purposes such as (building materials, electrical and electronic equipment, automotive) and industrial materials (such as engineering film) and other fields.
