Photodegradable Moisture-Proof Tear Resistant Stone Paper 40-100gsm Synthetic Paper For Disposable Packaging
Stone paper is made using calcium carbonate, a compound found in rocks, and bio-resin. The two materials are combined to form a non-toxic and recyclable material that has the texture and look of regular paper. The production process involves crushing the calcium carbonate into powder, melting the resin, combining the two ingredients together and then cooling them. Once cooled, the mixture is extruded through rollers which form sheets of stone paper. The sheets are then cut into desired sizes for use as stationery items such as notebooks or cards.
The stone paper production process is an invention from Taiwan. Over the past 20 years, a technology was developed to produce paper with less impact on the World than traditional pulp paper. The stone paper now has a Cradle to Cradle silver certificate and the technology is spreading rapidly around the World. We would like to share the basic process of making stone paper.
The stones used for the production of stone paper are calcium carbonate, and come from mines. The color of the stones, is the color that the paper will take on. Therefore, mainly white/yellow-white stones are used.
These stones are ground to dust, then mixed with a little (partly recycled) HDPE. This component functions as ‘glue’ for the stone minerals. Due to this combination of resources, recycling of the material becomes infinite. The Calcium Carbonate minerals don’t lose their form, as opposed to pulp paper fibers that do break after recycling and end up as waste in the end.
The heated mix of HDPE and dust pellets, become a texture comparable to a balloon. This mixture can be stretched out very high, and thus as thin as wished for. At the same time the material cools down and can then be rolled up into paper rolls.

1. One ton stone paper can save 20 trees.
2. One ton stone papercan save 280Kw /H electric energy.
3. One ton stone paper can save 7480 gallons clean water.
4. The stone paper production area was only 1/10 of the traditional
fiber factory.
5. Stone paper production need only circulating cooling water, the
traditional fiber paper produces a large amount of wastewater.
Stone paper combines advantages of paper and plastic
Stone paper bags and promotional materials are the ecological and
modern alternative to traditional plastic carrier bags. If you want
to make your high-quality advertising media sustainable in the
future, then you have come to the right place. Stone Paper Products

“Stone paper” is a revolutionary limestone material, a naturally
occurring resource. Not only because of its environmentally
friendly manufacturing method, it is a real alternative to the
usual materials such as paper or plastic, and the elegant
appearance makes your advertising materials a complete success.
Like polyethylene, Stone Paper is durable and waterproof. However,
as it decomposes into dust again only after a short time due to the
influence of wind and weather, it can compete with biodegradable
plastic. Due to its easy formability and foldability as well as the
extremely high-quality look and feel, stone paper is comparable to
classic paper and just as easily printable.
Stone paper products bring with them all the advantages they expect
from a quality carrying bag. Compared to a paper or plastic bag,
however, they hardly pollute the environment.
Due to its stability and its modern design, the stone paper bag can
also be used as an alternative to fabric or jute bags. Although the
popular printable fabric bag is often made from organic cotton, the
water used to make this material is gigantic.
