About MJ

Five decades of responsibility,
shaping a sustainable future.

For more than five decades, MJ has grown under a family-run philosophy that values integrity, responsibility, and long-term commitment. Across three generations, our guiding principle has remained constant : to operate not as a manufacturer that simply produces materials, but as a company accountable to the next generation through responsible and sustainable management.

We believe a single material—PET—can help make the world better. Guided by this belief, MJ produces only 100% recycled PET-based fibers and sheets, exporting environmentally responsible materials that contribute to global carbon-reduction efforts. For us, sustainability is not a market strategy; it is a fundamental duty of a materials company.

Built on people, guided by values, and driving
sustainable growth for the next generation.

People-centered management is also at the heart of MJ. Through internal welfare programs, performance-linked rewards, and a workplace culture built on shared growth, we strive to ensure that every employee moves forward with the company. We believe individual success strengthens collective competitiveness, and collective achievements elevate the company as a whole.

Our 50-year history is our strength, our multi-generation philosophy is our foundation, and our values guide the next 50 years.
MJ will continue to advance the value of recycled resources, responsible manufacturing, and people—driven growth—setting a global standard for the sustainable materials industry.
