What Is Stone Paper

The primary ingredient in stone paper is Calcium Carbonate (CaCO3) which comes from stone or rock, so stone paper is also called rock paper.

Stone Paper is made from crushed stone powder, combined with a non-toxic and recyclable binding agent HDPE (High Density Polyethylene). Stone paper is an extremely environmentally friendly paper which is different from traditional paper because it has non wood-pulp.

Making stone paper is a patented paper making technology which will not pollute air and water.

No chlorine or acids are utilized in the production process, and the resulting stone paper is completely non-toxic, and is even food safe.

Stone Paper is photo-degradable; it will gradually degrade when exposed to direct UV light. It will crack like an egg shell and turn back to calcium carbonate, regaining its original stone form over time.

It is not a synthetic paper, it is simply a very durable paper made from stone. It is a smarter option for uses that demand durability, superior quality and environmental properties.

Below are the key benefits of Stone Paper:

• 100% Tree Free
• Water Proof
• Tear Resistant
• Durable

RICH MINERAL PAPER HISTORY
Stone paper is also called rich mineral paper which is made mainly from dusty stone with 75% percent polyethylene and 25% percent adhesive. This kind of paper is waterproof, hard and uninflammable, and the most important thing is that there is no need to cut trees, which is very environmental.

The paper made from stone looks ordinary from the appearance, but if you write something and immerse it in water for ten minutes, the character is same as before, and the paper still can be written when you make it dry. If you burn rich mineral paper and general paper at the same time, you will find that the general paper burns to the ground quickly , on the contrary, fire of rich mineral paper is becoming smaller and smaller till it puts out.

The technology was developed successfully in domestic in the 1970s. However, it failed to get promoted because of the neglect to environmental protection and the situation of cost at that time. In recent years, rich mineral paper has made some breakthrough in the aspect of technology so that the reversal of cost took place and it is widely used now, such as notebook, paper bags and plates. At the time of taking environmental protection seriously, the technology will draw much attention from people gradually.

The new kind of paper is made from much inorganic mineral powder and little plastic resin whose function is similar to traditional wood pulp paper. It has got patents in more than forty countries, China, America, England, France, Germany, Italia, Australia and Canada and so on. Its working process is a unpolluted way without cutting trees, using water, discharging of gas and wastewater. Besides, rich mineral paper is recyclable. It will turn into dust after isolation without waste and then return to nature. It meets the standard of American Food and Drug Administration.
