The Mitsubishi Chemical Group (the MCG Group) is pleased to announce that it has developed new biodegradable biopolyester resins with a high biomass content and flexibility among other features.

The newly developed SA916N and SA916F are biodegradable resins which are degraded by microorganisms found in nature. Their high biomass content of over 60%, flexibility, high tear strength, and excellent processability have been achieved thanks to the MCG Group's proprietary material design and manufacturing technologies. They can be used for various applications such as food packaging, plastic grocery bags, and agricultural mulch film.

As a specialty materials group that provides innovative solutions, the MCG Group is committed to further advancing our technological development to provide high-value-added products and contribute to the realization of sustainable societies.
