Recycled Board Paper Double Coated Stone Paper RBD350 Eco Friendly Waterproof Tearresistant For Cover Page Origami
Stonepaper is an innovative material, which can replace conventional paper due to its properties and is used as an ecological alternative for many applications, even for plastic. Stone paper is a sustainably produced substitution product to regular paper.
“Paper” might be a misleading term regarding this context because paper is associated with trees, wood and cellulose. Stone Paper, or Rock Paper, as being the product made out of the so-called limestone flour, does not contain any cellulose! Shortly: Stone paper is not paper, but consists of up to 80% limestone and 20% additives. Therefore this treeless alternative would have to be correctly described as paper alike. A very informative contribution was produced Stone paper: No trees felled, no drinking water consumed.
Stone paper is made out of powdered limestone (calcium carbonate). This type of paper is more tear-resistant than conventional paper, even at low grammages. Moreover this material is extremely hard-wearing. Additionally, the flame retardant material is water-resistant, as well. Since neither wood fibres nor water are needed in the production process, stone paper is a sustainable and environment-friendly material. It also convinces with its noble and velvety feel. Due to its stability, it can also be described as rockboard.
An environmentally sustainable solution, this revolutionary stone paper making technology enables the production of paper without the need to fell trees, pollute water or release harmful gaseous wastes during production. By replacing 1 ton of wood pulp paper with 1 ton of stone paper, we can save 20 trees, save 7480 gallons of water and reduce 900kg of CO2. Paper Weights: 280g only

FAQ
Stone paper consists of the following components only: Calcium carbonate and high density polyethylene. If it is no longer needed, there are various disposal options. Stone paper begins to dissolve under constant sunlight after a few months. After about a year it will be dissolved in dust completely – similar to eggshells. Stone paper can also be burnt without creating toxic gases. For this reason, it is particularly suitable for the typical consumer product carrier bags.
80% limestone powder and 20% HD polyethylene. Limestone, one of the most abundant raw materials, comes as a waste product from quarries. The plastic, which serves as a binding agent, can be obtained from old plastic bottles, from maize or sugar cane waste.
Rock Paper can be printed just as easily as conventional cellulose paper. There is even less ink required. Offset, Digital and UV printing are the ideal technologies for printing stone paper. Laser printers are rather unsuitable because they often develop strong heat. Stone paper starts to deform at 65 degrees Celsius.
Yes, stone paper is more environmentally friendly than plastic. If plastics are not recycled they practically do not rot – unlike the paper substitute stone-paper. After several hundred years, plastic products will still be found in forests and oceans. Stone Paper contains only 20% of the plastic HD-PE (high density polyethylene). It consists of carbon and hydrogen atoms and burns completely to CO2 and water.
Rock paper can be printed just like plastic. There might be other printing methods used, nevertheless the result is just as good. Offset, Digital and UV printing are ideally used to print Stone Paper. Laser printers are not suitable as they often generate high heat. Stone paper can only withstand temperatures up to 65 degrees Celsius.
A big advantage of Stone Paper is that it does not become yellow. Even without the use of bleach, it is beautifully white and remains so. Moisture cannot harm the material. That is why the “paper” can in principle last forever. Unless it is exposed to permanent sunlight, because under prolonged sunlight, stone paper will decompose after a few months.

Yes, stone paper is more environmental-friendly and sustainable than recycled paper. Hardly any fresh fibres are needed to recycle paper, but a lot of drinking water, bleach and other chemicals. There is still a lot of waste, more than in the production of virgin fibre paper. Moreover, because of its appearance, eco-paper is not suitable for all applications.
