Stone paper, also known as limestone paper, stone paper, commonly known as bioplastic paper, mineral paper, or rich mineral paper, is a type of strong and durable paper-like material made from calcium carbonate bonded with a small amount of resin, high density polyethylene (HDPE) . It is used for stationery, brochures, posters, books, magazines, bags, packaging, wallpaper, adhesives, labels, in-mold labels, plates, trays, containers and cards, among others.

Stone paper is made up of 3 components: calcium carbonate, high density polyethylene (HDPE) and usually a proprietary coating developed by the individual supplier. High density polyethylene is a non-toxic resin. The proprietary coating is used to improve print quality and performance for applications in printing papers.

Stone paper has a density range of 1.0 to 1.6 g / cm3, which is the same as or slightly higher than normal paper, and a texture similar to that of the outer membrane of a boiled egg. It can be recycled with number 2 plastics or reprocessed into rich mineral paper and is non-biodegradable, but photodegradable under suitable conditions.

Because stone paper is not made from wood fiber, it has a smoother surface than most traditional paper products, so no coating or lamination is required. The source of calcium carbonate is waste material from marble quarries and waste that is ground and reduced to fine white calcium carbonate powder. No water, acid, bleach or optical brighteners are used in the manufacture of stone paper. It can be recycled indefinitely, but only if it is recycled separately at public facility sites.
