This is a standard production line. If need, we can design according to your requirements.
Stone paper is a natural product manufactured from calcium carbonate, using proprietary additives as a bonding agent.
The calcium carbonate is collected as waste materials at existing limestone quarries and is ground up into a fine white chalk powder. A small quantity of non-toxic resin is then added and together these materials are converted into a printable substrate.
Nowadays, stone paper can substitute for wood pulp paper in many fields,
such as printing, packaging, decorating…
As technology of making stone paper gets maturer, its application fields will be greater!
