Stone paper is a type of specialty paper that is made from calcium carbonate 80% (limestone) and bio-polyethylene resin 20% (HDPE). The HDPE is used as a binder. Stone paper is an extremely environmentally friendly paper which is different from traditional paper because it has non wood-pulp.
Made From Stone Powder
Stone paper is a type of paper that is made out of calcium carbonate 80% (limestone) and bio-polyethylene resin 20% (HDPE). In this case, the HDPE is used as a binder. Thereby, limestone from existing limestone quarries is being used as the raw material and processed into a fine powder.
Without Chemical Bleach
The color of Stone paper is originally white, therefore it does not require any further bleaching process. Because of its high density, stone paper products also retain their shape over time.
Waterproof and Washable
Due to its composition, stone paper is waterproof, resistant to grease and washable. The feel is similar to that of tissue paper.
Back to Nature
Stone paper is disposed and recycled in the normal way. So stone paper is turned back into calcium carbonate and becomes limestone again.
When we use one tone stone paper instead of tradition wood-pulp paper, we can saving much energy as follow:
Stone Paper Combines Advantages of Paper and Plastic
"Stone paper" is a revolutionary limestone material, a naturally occurring resource. Not only because of its environmentally friendly manufacturing method, it is a real alternative to the usual materials such as paper or plastic, and the elegant appearance makes your advertising materials a complete success.
Like polyethylene, Stone Paper is durable and waterproof. However, as it decomposes into dust again only after a short time due to the influence of wind and weather, it can compete with biodegradable plastic. Due to its easy formability and foldability as well as the extremely high-quality look and feel, stone paper is comparable to classic paper and just as easily printable.
Stone paper products bring with them all the advantages they expect from a quality carrying bag. Compared to a paper or plastic bag, however, they hardly pollute the environment.
Due to its stability and its modern design, the stone paper bag can also be used as an alternative to fabric or jute bags. Although the popular printable fabric bag is often made from organic cotton, the water used to make this material is gigantic.

What is Rich Mineral Paper?
The main raw material of new technology what we called rich mineral paper is the richest calcium carbonate in the crust, taking high polymer material and many kinds of inorganic substances as auxiliary raw material, it is a new kind of papermaking technology that is recyclable by making use of high molecular surfactant chemical principle, filling modification technique and special process. It is a new world-leading technology at home. It can not only solve the problem of pollution caused by traditional paper making but also solve the problem of white pollution and the waste of oil resources from plastic packaging. Productive process of Rich Mineral Paper
Firstly, extract the calcium carbonate from limestone and then mill mineral into high calcium 1500-2500 ultrafine powder. Secondly, add 15% additive to 85% modified calcium carbonate to make masterbatch. Finally, make paper and bags through extrusion and blowing equipment.
Characteristics
In the working process of rich mineral paper, there is no need for water and organic chlorides like the strong acid, strong base and bleaching powder. It don't have several important links which will cause pollution than traditional paper technology, such as stewing, washing and bleaching so that the pollution problems caused by three wastes in the process of producing paper can be rooted out. At the same time, its cost is 20-30% lower and its price is lower 10-20% than the traditional paper because its main raw material is cheap mineral flour.
Types of Rich Mineral Paper
It has a wide range of application. It can be used in disposable goods like rubbish bags, shopping bags, food bags, compact bags, plates, podotheca, gloves, tablecloth, raincoats and dust sheets; in the cultural paper, such as printing paper, writing paper, advertising decoration paper, glazed printing paper, coated paper, membrane paper, drawing paper, poster paper, typing paper, flat envelops, cigarette paper, glassine and newspaper; in decorative building materials like decorative wallpaper; in the industrial packaging field, such as seed packets, bags of cement, rice bags, garment bags, various handbags and paper boxes; in special aspects, such as field operation paper, underwater operation paper, undermine operation paper and military paper. Its range of use is really wide and will be wider with the development of rich mineral papermaking technology. The cost of rich mineral paper goods is lower 20-30 percent than alternative paper goods so it has a powerful competitiveness and a bright market prospect.
