Japan developed a new type of flexible packaging films of the polylactic acid

Toray Japan took the lead in the world to successfully develop a polylactic acid packaging film made of plants. This film has the flexibility and heat resistance originally possessed by polylactic acid, and also has flexibility that can be rolled up and can be completely degraded. In addition to the new technology developed by Toray this time, a biodegradable high-performance alloy component that can interact with polylactic acid and has a high mobility unit has been designed. In addition, high-precision two-axis extension technology allows crystals to be regularly arranged to improve the flexibility of the film, overcoming the shortcomings of previous changes in external conditions such as temperature and pressure, and the transparency and flexibility that change over time.
