One would think that stone and paper would not fit together. However, the game “Rock, Paper, Scissor”, in which stone and paper are opponents, has changed a lot. 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 by Südwestrundfunk (SWR): Insider tip 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.
