Papermaking From Stone Machine Production Line

Stone Paper (also known as rock paper, paper from waste marble, mineral paper, or rich mineral paper) is a paper-like product manufactured from calcium carbonate bonded with high-density polyethylene (HDPE). 

Stone "paper" consists of roughly 80% calcium carbonate, 18% HDPE and 2% proprietary coating.It has a density range of 1.0–1.6 g/cm3, which is equal to or slightly higher than that of ordinary paper, and a texture somewhat like that of the outer membrane of a boiled egg. It is not biodegradable or compostable, but is photo-degradable by the ultraviolet (UVa) light in daylight.Thus stone "paper" does not meet archival standards and requires special measures for long-term conservation.

Because it is not made from cellulose fibers, stone paper can have a smoother surface than most traditional products, eliminating the need for additional coating or lamination.The calcium carbonate is mined from quarries or precipitated from limestone.The production of stone paper uses no acid, bleach or optical brighteners.It can be recycled into new stone paper, but only if recycled separately at dedicated civic amenity sites or other recycling/waste processing points.

Stone paper products are compatible with inkjet or solid ink printers (e.g., offset, letterpress, gravure, flexographic) but do not respond well to very high temperature laser printers.

Compared with Traditional Paper (wood pulp paper), Stone Paper has many competitive advantages.

Eco-friendly Per ton Stone Paper can save 20 trees, save 7480 gallons clean watrer, save 6 millions BTU energy, reduce 236 pounds carbon emissions, reduce 42 pounds liquid waste discharge, reduce 167 pounds solid waste discharge. 
               
Less production cost  

At least reduce 30% production cost, compared with Traditional Paper.

Waterproof
Can be used as waterproof materials, such as outdoors maps, cement bags...

Recyclable
After converted into pellets, it can be used again.
