Recycled Water Proof Tear Resistant Stone Paper 120gsm Synthetic Paper Hot Sealing For Stationery Disposable Bag
Stone paper consists of the following components only: Calcium carbonate and high density polyethylene. If it is no longer needed, there are various disposal options. Stone paper begins to dissolve under constant sunlight after a few months. After about a year it will be dissolved in dust completely – similar to eggshells. Stone paper can also be burnt without creating toxic gases. For this reason, it is particularly suitable for the typical consumer product carrier bags.
80% limestone powder and 20% HD polyethylene. Limestone, one of the most abundant raw materials, comes as a waste product from quarries. The plastic, which serves as a binding agent, can be obtained from old plastic bottles, from maize or sugar cane waste.
Rock Paper can be printed just as easily as conventional cellulose paper. There is even less ink required. Offset, Digital and UV printing are the ideal technologies for printing stone paper. Laser printers are rather unsuitable because they often develop strong heat. Stone paper starts to deform at 65 degrees Celsius.
Yes, stone paper is more environmentally friendly than plastic. If plastics are not recycled they practically do not rot – unlike the paper substitute stone-paper. After several hundred years, plastic products will still be found in forests and oceans. Stone Paper contains only 20% of the plastic HD-PE (high density polyethylene). It consists of carbon and hydrogen atoms and burns completely to CO2 and water.
Rock paper can be printed just like plastic. There might be other printing methods used, nevertheless the result is just as good. Offset, Digital and UV printing are ideally used to print Stone Paper. Laser printers are not suitable as they often generate high heat. Stone paper can only withstand temperatures up to 65 degrees Celsius.
A big advantage of Stone Paper is that it does not become yellow. Even without the use of bleach, it is beautifully white and remains so. Moisture cannot harm the material. That is why the “paper” can in principle last forever. Unless it is exposed to permanent sunlight, because under prolonged sunlight, stone paper will decompose after a few months.

Yes, stone paper is more environmental-friendly and sustainable than recycled paper. Hardly any fresh fibres are needed to recycle paper, but a lot of drinking water, bleach and other chemicals. There is still a lot of waste, more than in the production of virgin fibre paper. Moreover, because of its appearance, eco-paper is not suitable for all applications.

Unique characteristics of Stone Paper
MADE OF STONE DUST
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.
WITHOUT CHEMICAL BLEACH
The color of Stone paper is originally white, therefore it does not require any further bleaching process. Because of its high density, stone paper products also retain their shape over time.
WATERPROOF AND WASHABLE
Due to its composition, stone paper is waterproof, resistant to grease and washable. The feel is similar to that of tissue paper.
BACK TO NATURE
The products are disposed and recycled in the normal way. Here, the stone paper is turned back into calcium carbonate and becomes limestone again.
