Synthetic Board Paper Waterproof Tear Resistant Ecofriendly Stone Paper 375 - 600gsm Biodegradable For Box
Stone paper is a completely non-toxic, biodegradable alternative to paper. It is suited for many types of printing including offset lithography and screenprint. True to the name, Stone paper consists mostly of calcium carbonate, a substance found in rocks and is completely tree-free. The paper will degrade safely, without the exhaustion of harmful gasses, and be completely gone in 9 to 12 months if left in nature. It can also be easily burned without the release of harmful gasses.
The primary ingredient in stone paper is Calcium Carbonate (CaCO3) which comes from stone or rock, so stone paper is also called rock paper.
Stone Paper is made from crushed stone powder, combined with a non-toxic and recyclable binding agent HDPE (High Density Polyethylene). Stone paper is an extremely environmentally friendly paper which is different from traditional paper because it has non wood-pulp.
Making stone paper is a patented paper making technology which will not pollute air and water.
No chlorine or acids are utilized in the production process, and the resulting stone paper is completely non-toxic, and is even food safe.
Stone Paper is photo-degradable; it will gradually degrade when exposed to direct UV light. It will crack like an egg shell and turn back to calcium carbonate, regaining its original stone form over time.
It is not a synthetic paper, it is simply a very durable paper made from stone. It is a smarter option for uses that demand durability, superior quality and environmental properties.
