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.
Due to its composition, stone paper is waterproof, resistant to grease and washable. The feel is similar to that of tissue paper.
