Stone Rock Synthetic Paper Sheet Production Line Making Machine

What is Stone Paper?

Stone Paper (also known as Rock Paper, Mineral Paper... ) is a type of strong,

and durable paper-like product manufactured from calcium carbonate bonded with high-density polyethylene (HDPE).

Nowadays, it is widely used in printing industry (such as wallpaper, magazine, notebook, poster, label...)

and packing industry (eg. packing bag, plate, tray, container, box...).
