Our mission
Bring mineral-rich material innovation into practical products, addressing resource use and waste through material, process and product development.
About Shanlian
Shanlian develops the PMU mineral-rich material platform through formulation, compounding, conversion, application engineering and compliance qualification. The company works as a material-technology and manufacturing partner for defined product needs.

Approximately fifteen years of exploration connect a packaging-industry background with mineral-rich material development. The aim is practical: bring the material into everyday products, not leave it in the laboratory.
Cai Jianyong’s packaging-industry background led to an early material concept in 2006. Focused R&D began around 2010, followed by repeated formulation and processing trials, a film/process breakthrough in 2016 and industrial development at Changxing in 2017.


Cai Jianyong brings more than thirty years of printing and packaging experience. He developed an early material concept in 2006 and began focused R&D around 2010.
Repeated formulation and film-processing trials connected the material idea with manufacturable products. The 2016 film/process breakthrough preceded industrial development at Changxing in 2017.
Approximately fifteen years of exploration link mineral-rich material research with practical applications. The work continues through grade development, processing trials and application-specific qualification.
Bring mineral-rich material innovation into practical products, addressing resource use and waste through material, process and product development.
