What is the paper made from stone?
STONE PAPER is a new product which is made from Calcite. This paper has created a new revolution in the film and paper industry. Surprisingly, Calcite is a rich natural resource worldwide.
It is made of stone instead of wood and polymer instead of water. In fact, instead of wood, calcium carbonate powder is used in its structure. It looks like matte/glossy paper and has a soft, velvety surface.
In terms of replacement with some traditional paper, it can save a lot of forest resources. In terms of replacing traditional plastic packaging, it can also save a lot of oil resources in countries and bring less plastic into the environment.
We believe that STONE PAPER will contribute to the goals of sustainable development. In fact, this product is a new generation of paper and plastic products in various industries.
In order to do this, our group of companies has an investment in stone paper technology and machinery. Certainly, the future belongs to people who invest in this industry.
Features of Stone Paper Production Line (Taiwan Cement Stone Paper Bag)
The production process of stone paper is simpler than wood pulp paper and does not use wood pulp. The stone paper manufacturing process does not use strong acid-based, and bleach, so it does not create chemical wastewater. The process of making paper from stone is an environmentally friendly paper-making technology that is recognized by the Cradle to Cradle Institute.
The biggest point of this production, which is an innovative production process, is that it conserves water resources and reduces CO2, so it can reduce the degradation of our environment.
Continuous Granulation Machine
This machinery includes a Weightless automatic metering, feeding system, and Continuous internal mixer with double rotors. Also, it has a Forced feeding device, a single screw extruder, and a Die surface hot cutting auxiliary system.
According to the properties of high-filled calcium carbonate, we designed this machine specially. Steel alloys with excellent wear resistance were used to make this product. There is a cooling water supply to control the temperature of the machine.
Barrels of materials are individually controlled at different temperatures by electric heating and water as cooling.
Special hydraulic flow controls discharge port, which can adjust the mixing degree of materials; External circulation shaft seal lubrication, labyrinth type shaft end seal structure, automatic cutting device.
Granule made by Continuous compact granulation goes in the Blowing stone paper-making process. The thickness of the product ranges of the Blowing machine are from 100 to 180μm with a low density of 0.9 ~ 1.2 g/cm³. Its appearance is very similar to that of wood pulp paper, and surely it can replace most of the wood pulp paper.
The paper can satisfy the expectations of the printing process, so it can be used as a cultural paper to print notebooks, books, posters, magazines, and so on.
Generally, these products replace double-adhesive paper, coated paper, and non-stick paper in wood pulp paper.
Granule made by Continuous compact granulation goes into the Casting stone paper-making process. The thickness of the product ranges of the Casting machine are from 150 to 500μm with a density of 1.3 ~ 1.6 g/cm³. The appearance of the product is similar to that of white card paper, so can be used for some light boxes.
The product meets the requirements for the printing process. It is mainly used for paper boxes, cardboard products, disposable meal boxes, and dinner plates, as well as waterproof cartons, etc.
It is a One-step machine with a calendering paper-making process. The Rolling product has a thickness of 120 to 800 μm and a density of 1.3-1.6 g/cm³. Interestingly, the Rolling product looks like photo paper. Therefore, this product meets the requirements of the printing process completely. And also emboss, blister, coat, adhesive, UV varnish, etc.
This product has a wide range of applications and can be used as handbag paper, packaging paper, decorative paper, label paper, special paper, etc., such as wood grain decorative film on the surface of high-density artificial board, wallpaper, handbag, imitation leather pattern paper, book cover, fine packaging carton, etc.
All stone base papers produced by the Blowing method, Casting method, and/or Rolling method need to be coated by the Coating machine. The coating liquid surely must be prepared according to the formula.
The base paper coat on the coating machine by the reverse rotary method by forming a reverse velocity difference between the paper surface, the coating roller, and the coating material supply roller. Then it can evenly and stably adhere to the paper surface. After drying in the oven, repeat the same operation to coat the back of the paper. And finally, the stone paper roll stabilizes by constant tension.
Coated products are used for writing, printing, and making books, magazines, booklets, brochures, maps, handbags, cardboard boxes, and other products.

Characteristics of Stone Paper
1. Features such as high-quality printability, soft texture, low price, and also waterproofness of this paper, have made it an interesting product superior to cellulose paper.
PP/PE environmental stone papers, on the other hand, are manufactured with technology that is new when compared to traditional synthetic papers.
Consequently, there are obvious improvements in printing, uniformity, static separation, and drying performance.
One of the important points in the printing industry is that ordinary printing ink can be used and the printing cost is only one-third.
2. PP/PE stone paper production fully meets environmental conditions. Furthermore from good waterproof properties, it has other advantages such as:
- Prevent insect damage,
- Light resistance,
- Good light reception quality,
- Abrasion and heat resistance (no deformation below 100).
Main Applications of Stone Paper
Stone paper can be used with higher quality printing, longer lifespan, and lower cost for many kinds of printed matters like:
- Catalog, Business card, Advertising brochure,
- Book cover, and so on.
Stone Paper is very suitable for printing valuable books and important documents due to its higher resistance to tearing than traditional papers, so it can be stored for years without damage.
In addition, the below products can be made from stone paper:
- The cover plate of the scanner and duplicator,
- Special steel label,
- The surface paper of the quartz clock,
- Mechanical scale,
- Wall decorative paper,
- Cement Stone Paper Bag, etc.
Predictably, PP/PE synthetic paper can almost replace traditional synthetic paper in more and more fields.

Less production cost
The cost of producing stone paper is 40% lower than traditional paper production, so as a result, this product is also economically viable.
The competitive advantage of stone paper V.S. wood pulp paper
- The cost of raw materials is lower than wood pulp paper.
- The capital investment required is less than wood pulp paper.
- The cost of production is lower than wood pulp paper.
- Stone paper’s characteristics such as stretchability, durability, and water resistance are better than wood pulp paper in the same thickness comparison.
- Smoother surface and its natural whiteness with better printing effects.
- Water-resistant and will not wrinkle or damage when wet. Change in moisture will not cause shrinkage or extension. The paper will not be fuzzy on the surface thus preventing bacteria growth.
- Heat-setting characteristic works great with hot melt glues.
- Termites are free and moth-free under room temperature.
- Stone paper can be recycled by converting it into recycled pellets for further manufacturing. If disposed of garbage and sent to incineration, the remaining mineral powder can be returned to the earth.
This kind of paper can be used as waterproof materials and it is suitable for outdoor maps cement bags, etc.
After being converted into pellets, it can be used again.
Stone Paper finished product samples
What standards has this product received?
Since this product can be decomposed under the conditions of sun, wind, and rain, and this product can also replace non-decomposable plastics and reduce white pollution, therefore, stone paper from the European Union and the US FDA certified the grade of materials. Received food, REACH, ROHS, and other standards.
In what GSM are stone papers produced?
This type of paper is produced in weights of 90 to 1200 and is used for all kinds of notebooks, books, posters, handbags, boxes, wallpapers, etc. These products have more strength in high thicknesses and the possibility of tear is very low. One of the most important applications that this product can have is in the field of packaging (soft and hard).
What is the cost of producing stone paper?
The cost of paper production with this technology is reduced by up to 40%. Because its main ingredient is calcium carbonate it is very cheap. Also, its production process is short, so its production cost is low.
What is the difference between cellulose and stone paper?
The existence of short and long fibers in ordinary cellulose type causes ink suction and in multi-color printing, we will not have the desired quality, so to have a higher quality printing, glossy paper is used, the price of which is higher. Stone paper gives us the quality of cellulose glossy paper at a lower price and the printability of this product is much better than ordinary paper.
What are the disadvantages of stone paper?
In fact, the points that we express in this section can not be considered as the drawbacks of this product. Because it is an advantage in some industries and increases the efficiency of rock paper.
Stone paper does not absorb water.
It can be stated that the surface of stone paper is completely impermeable to all foreign materials except air flow and does not absorb any material. This lack of absorption of materials for gluing and laminating stone paper does not cause a problem. Polymer and thermal adhesives can be used instead of water-based adhesives. As a result, this paper is not suitable for the production of toilet paper and tissues and can not be used in this industry.
Stone paper is sensitive to temperatures above 100 degrees.
Stone paper texture is vulnerable to high temperatures and UV exposure and completely loses its shape. Therefore, laser printers can not be used for printing. Because it does not work properly and wrinkles. Of course, this defect is very useful when a stone paper is decomposed and causes this paper to decompose in the sun and return to the cycle of nature.
Why is the print quality on stone paper higher than cellulose?
Acceptance of ink in lithographic paper is very good and the quality of printing with ink reaches 2880 DPI because there is no fiber in this paper and nano-sized powder slurry has made its surface very desirable for printing. In fact, 720 DPI printing in this product is the same as 1440 DPI printing quality in cellulose type.
With excellent printability and no need for additional printing services, this paper has become a suitable product for printing and packaging. Printing on this product saves printing time and running costs.
This paper is a great option for printing. The homogeneous and uniform texture, in addition to the absence of cellulosic fibers, means that additional printing services are not necessary.
Complementary printing services are a set of processes such as coating, laminating, cellophane coating, etc., which increase the resistance of thin and brittle cellulose fibers in ordinary papers to factors such as moisture, dust, and temperature changes.
The absence of short and long cellulose fibers and the homogeneous and homogeneous texture of rock paper causes the ink not to penetrate its inner texture and consumes the ink to a much lesser extent than other papers.
What are the effects of cellulose and stone paper on printing machines?
The presence of lint on the texture of ordinary paper reduces the useful life of printing machines, while stone papers have no lint on their surface and are completely soft and velvety. Coating fluid in stone paper also prevents calcium carbonate from coming into contact with printing presses.
Are FSC or PEFC environmental and sustainability certifications required for stone paper products?
Due to its creative manufacturing process, the environmental certifications and sustainability of this product are different from wood fiber paper. Due to the lack of wood fibers, no forest management certification such as FSC or PEFC is required for stone paper.
How can stone paper be useful in landfills?
In some countries, such as New Zealand and Australia, waste management companies use calcium carbonate as an accelerator in waste decomposition. This type of paper with a high level of calcium carbonate contributes significantly to waste management companies in the waste management system.
How long does it take for polyethylene (HDPE) to degrade?
HDPE in stone paper is non-toxic and takes about 6-18 months to begin to decompose, depending on the intensity of the UV.
Is stone paper suitable for office laser printers, photocopiers, or toner printers?
No. This product is not yet suitable for laser printers or photocopiers because the sheet made of calcium carbonate and polymer can be decomposed in light, meaning that it is damaged by the intensity of ultraviolet light. When UV is used in laser printers and ultraviolet light shines on the paper, the product reacts to ultraviolet light and initiates the destruction mechanism. Therefore, laser printers are not currently suitable for printing on this product. Stone paper for toner printers is still under development.
What type of printing method is suitable for stone paper?
1- Web/sheet offset lithography
2- Web/sheet UV offset lithography
5- Low-temperature digital devices (solid ink/latex)
