Biodegradable Moisture-Proof Tear Resistant Stone Paper 168gsm Synthetic Paper For Stationery Map

Stone Paper is type of paper that is made from crushed stone. It’s idea is about sustainable development with respect to our planet. By using mineral power (Calcium Carbonate) Stone Paper bags and packages are tree-free, and no water or bleach is used during production, which is the case during the production of traditional wood pulp paper.

Stone paper has some attractive characteristics as a writing material. At first touch, you can tell the sheets aren’t normal wood-based paper. The pages are smoother, and you have to make an effort to tear them. Ink writes just as well, or perhaps even better, although some gel inks may take a minute or two to dry completely. In many ways stone papers like Repap seem to reinvigorate paper with aspects you always wished paper had. It’s durable, oil and tear resistant, and waterproof, and since you can fold it like paper your airplane-making days may not be as numbered as you thought before.

Stone Paper has the following characteristics:
1. Adsorption: Stone paper and ink have strong affinity and adsorption, easy to color when printing, not easy to decolorize; 2. Waterproof: The words written on stone paper, color ink soaked in water will not fade; 3. Flexibility: have good tensile and tear resistance, and have a good flexibility; 4. Appearance: smooth surface, good brightness, high resolution, three-tier structure; 5. Environmental protection: Automatic weathering and no pollution in the wild environment; 6. Writing: writing fluent, easy to color, writing feel good; 7. Printing: can be used for lithography, gravure, convex screen printing, etc., because of the technology of paper production of stable quality, good finish, not easy to tear, easy to print, not afraid of water, not worms and other advantages in the international market The selling price is very high.

In the stone paper production process, the factory simplifies a crushing process, because the broken stone generates a lot of dust, causing harm to the environment and the human body. Therefore, the calcium carbonate production process is generally carried out by a quarry. After the stones are crushed, the quarry mill uses a calcining process to produce hydrated lime or lime. The main component of this lime is calcium carbonate, and then the lime is powdered. Bagging, the current retail price in the market is about 300 yuan a ton; if the stone paper mill is built in the stone-producing area, the crushing process can be separated from the production process. If the area is not a stone-producing area, you can purchase lime powder directly for stone making, and the cost will only increase by a few hundred yuan. Process flow: The process of producing synthetic paper using the combination of calendering and casting. The basic material of stone paper is polyethylene-PE and polypropylene-PP. Instead of a single casting machine instead of a calender, a combination of polyethylene-PE and polypropylene-PP is used in combination with calendering and casting, which is more suitable for the processing of polyethylene. The product performance is improved and the product is improved.

The production scope is more extensive. Production Process: Auxiliary - Modification - Granulation - Production - Thickness Measurement Additives - Products - Cutting - Coiling - Surface Treatment Raw Materials [Calcium Carbonate Powder, Resin (Plastic-Polyethylene PP, Polypropylene PE), Additives (Adhesives)]--Mixing-- Mixed Paper--Extrusion (Casting, Rolling)--Base Paper--Coating Cloth Treatment (Paper Spray Coating Solution)--Multilayer Film Treatment--Glossy Surface Treatment--Synthetic Paper (Coating Liquid)--Graphic Fabric Treatment

FAQ

1. What’s the environmental benefit of using stone paper as compared to regular tree pulp paper?

Stone Paper is produced entirely from recycled waste material and has a minimal impact on the environment, all the while 18 trees are required to be chopped down to produce 1.000 kg of pulp paper. Also it takes consumption of 2.770 liter of water to create 1.000 kg of tree pulp paper and with Roca stone paper any water consumption is prevented.

2. Are stone paper products recyclable?

Yes. Simply recycle it to Plastics (HDPE). But to let you know the production-process, and end-product are clean and non-wasteful. In addition, Stone Paper paper is easily broken down by sunlight; 200 micron thick G-ECO paper will begin to break and crack like an eggshell in the outside air in a period of 9 to 12 months (if the material is left in the sun 10 hours a day). It can also be easily burned without the release of harmful gasses.

3. What happens to different pens on this paper?

Ballpoints and gel pens will work perfectly fine! However, be aware that stone paper does not absorb ink, and it may take a second or two for gel based pen ink to dry. The good part of it is that it uses 15 to 20% less ink during print in comparison to wood pulp paper.

4. Do the pages tear?

Stone paper is very difficult to tear and will generally stretch before it tears. But when you are cutting it it works just as with traditional paper.

5. Can you fold Stone Paper?

Yes, you can create stone paper origami as easy as it is with regular paper.

6. Can I use it underwater?

Stone Paper is 100% waterproof and liquids have no effect on the material. If it gets wet, you can simply dry it.
