WHAT WE DOOur Initiatives
Since the United Nations adopted the SDGs in 2015, the soft packaging industry has faced the need to help realize a sustainable society, not only through efforts in the manufacturing stages such as material selection and package design, but also through efforts that encompass the entire value chain up to post-disposal processes.
With the use of NUCREL and HIMILAN, Dow-Mitsui Polychemicals Co., Ltd. proposes environmentally sound packaging that can help reduce the volume of packaging materials while still maintaining the content-protecting function required of soft packaging.
The SDGs are sustainable development goals for the year 2030 agreed upon
by the international community.

*1)These marks are would be the one which is valid based on the Japanese law for using various resources effectively.
*2)The peeling strength of the sealant layer itself is relatively lower, but these structure would show the maximum strength with the substrate’s failure during the measurement.
