Stone Paper is a product similar to plain paper with very similar capabilities, which was first invented in the 1990s by Long Meng Technology (TLM) and introduced to the world market.
The main ingredient of this type of paper is stone powder (calcium carbonate). In the production of stone paper, no tree is cut down and water are not wasted, so this type of paper is also called environmentally friendly paper.
Stone powder is supplied from the waste of stone factories and stone mines, which have a great abundance and the final product is returnable to nature at the end of its survival path.

Stone Paper is a product similar to plain paper with very similar capabilities, which was first invented in the 1990s by Long Meng Technology (TLM) and introduced to the world market.
The main ingredient of this type of paper is stone powder (calcium carbonate). In the production of stone paper, no tree is cut down and water are not wasted, so this type of paper is also called environmentally friendly paper.
Stone powder is supplied from the waste of stone factories and stone mines, which have a great abundance and the final product is returnable to nature at the end of its survival path.
It has features such as tear resistance, water insulation, degreasing, ability to write on stone paper under water, fire and flame resistance, washable, sun recyclability and many others.
stone paper is not just an alternative product in some industries, it has placed it in a higher position than other conventional papers or polymer films.
Stone paper printing can be easily done using common printing methods and machines. In addition, these papers have waterproof properties like synthetic papers. Please note that the following is just a guide, and given that the settings between different printers and operators can be different, trial and error in achieving an acceptable quality must be done by the printer operator.
The main constituents of stone paper are calcium carbonate, which contains up to 80% of stone paper, all of which are supplied by many minerals that are naturally and abundantly present in nature. Another main material used in paper composition is heavy polyethylene stone. Due to the change in the percentage of ingredients, density and type of application in different industries, stone paper is currently divided into four general groups:
Each of the above user groups has its own characteristics. In the field of traditional paper, the division is based on “heat”, but in the field of stone paper, it is based on “thickness” (microns), and the density coefficient for stone paper is different in different grades. For example, in grade SP, the density is 1, in grade ST and RB, the density is 1.5, and in grade RP, the density is 1.2.
Of course, it is necessary to explain that at present, efforts are being made in the factory to reduce the density of all grades by maintaining the quality of stone paper. In some cases, the relevant experts in the factory have succeeded in producing stone paper with a density of 0.8, which is very suitable for publishing. To buy high quality stone paper and inquire about the price of stone paper, you can refer to Atlas Iranian Trading Company.
SP series stone paper is suitable for food packaging applications. SP series stone paper is a suitable alternative to PVC, PP, PE and PET matte films. This paper has been 100% nature friendly (no tree felling, no brightening agent, no acid, no strong base and water saving) and a revolutionary process in paper production that provides safe, environmentally friendly materials for many Provides various applications.
SP series stone paper is suitable for all types of flexo and rotary printing. SP series stone paper is not suitable for copiers, laser printers and toner printers.
Stone paper is a type of ST or thermoforming paper that is the best option to replace plastic cardboard and heat-ductile paper types. This type of stone paper is more suitable for thermal applications (shaping paper using molds). The purpose of producing and presenting this product is to replace hard polymer sheets such as PET and PVC in similar industries.
RP type stone paper is a suitable solution for replacement with traditional pulp paper (pulp paper or cellulose paper). RP series stone paper is a thin, flexible, writable paper with natural white color and is very suitable for printing. This nature-friendly paper (without cutting down trees) is produced and lacks bleaching acid and a strong base, which saves water consumption. A revolutionary manufacturing process that provides environmentally friendly materials suitable for a variety of applications.
It is a suitable solution for replacing paper cardboard and plastic cardboard. RB Series stone Paper is a thick, sturdy paper with a natural white color and is very suitable for writing and commercial printing. This nature-friendly paper (without cutting down trees) is produced and lacks bleaching acid and a strong base, and its production process also saves water.
This paper has two very thin laminated layers of polyethylene on both sides and is suitable for packaging in the food and pharmaceutical industries.
According to the tests performed by the market development team of Atlas Iranian Company, SP series stone papers can be laminated with various types of polymer and aluminum papers and films and can be considered as a suitable material for replacing polymer films in the packaging industry.
IML or In-Mold Labeling means labeling inside the mold at the same time as producing the container by injection, pneumatic or thermoforming. In containers produced by this method, the label becomes an integral part of the container body. This method has many advantages over conventional labeling methods such as direct printing on dishes, adhesive back labels and other older methods.
In the process of producing containers by IML method, first the label produced with the same polymeric material or compatible with the container material is transferred into the mold by the robot and then the process of injection or extrusion of plastic materials is done. In this way, with the help of molten material, the label and the plastic container are integrated with each other, so that the label can no longer be separated from the body of the container in any way.
The main difference between Common labels and IML labels is that the conventional labels are placed on the surface of a plastic container but the IML label becomes part of the wall container.
In general, RP paper group has been developed for easy printing with all common printing systems such as offset, engraving, flexo and… in 6 different thicknesses. It should be noted that this paper can be printed on both sides due to the appropriate printing cover. This paper can be used to print a variety of books, Articles, catalogs and brochures, as well as to produce notebooks and organizers. Also, the unique properties of this paper, such as being waterproof and tear-resistant, have led to its use in the production of double-sided drawings, washable books, and waterproof books.
It should be noted that all post-printing processes such as UV, varnish and razor and folding, gilding and can be easily done on this paper and there is no need for cellophane to increase the strength of the paper.
One of the successful experiences of using stone paper is producing various types of adhesive back labels using RP paper. Currently, adhesive backing paper is available in the form of jumbo rolls with a width of 102 cm and a length of 1000 m with acrylic and hotmelt adhesives, as well as sheets with standard dimensions of 51 x 70 cm in Atlas Iranian Trading Company. For more technical information in this regard, refer to the articles section and ask the company’s sales unit for the price of stone paper and supply conditions.
RP series paper, due to its suitable structure on both sides, can be laminated with a variety of materials such as polymer films, kraft paper and aluminum foil.
As mentioned in the previous sections, RB series papers have been developed and marketed in order to obtain a material with cardboard properties. Its applications include the following:
ST series paper has been developed and marketed with the aim of competing with thick polymer sheets such as BOPP, BOPET and PVC. Due to the structure and amount of polymer used in the texture of this product, it can be easily formed against heat, so it is mainly used for the production of thermoforming containers, which is a more environmentally friendly solution than other polymer films.
1) Thermoform containers (STN or SFN): Plates, lunch boxes, bowls, fruit containers, fish and meat containers
2) Jelly molds (STN or SFN)
3) Perfume molds / Mobile box placement molds (STN or SFN)
4) Food boxes (STN or SFN): In this case, the box remain it’s beautiful shape even if placed in refrige and freezers!
5) Lighting (Fancy Ceiling Lights) (STN or SFN)
