Karst Stone Paper products have an indefinite shelf life and do not yellow or degrade over time like traditional paper. The paper is made from 80-90% crushed stone (calcium carbonate) and 10-20% non-toxic resin, which is used to bind the stone particles.
The end product is waterproof, smoother, brighter, and more durable than traditional paper. Karst Stone Paper is ISO 14001:2004 certified, alongside ROHS, REACH, and FDA, and has the C2C environment certificate. When left in nature, Karst Stone Paper is photodegradable and will be completely gone in 9 to 12 months without releasing any harmful gases. The paper is also recyclable with type 2 plastics.
If burned, Karst Stone Paper does not smolder like traditional pulp paper and no harmful gases are released. Karst Stone Paper is compatible with some printers, including inkjet and solid ink printers, but not suitable for laser printers or photocopiers that generate high heat. The paper works well with ballpoint pens, gel pens, and pencils, but may cause issues with fountain pens.
