1. Product introduction of stone paper:
Stone paper is a new material between paper and plastic. It can not only replace some traditional functional paper and professional paper, but also replace most traditional plastic packaging. And it has the characteristics of low cost and controllable degradation, which can save a lot of costs for users without pollution. From the perspective of replacing some traditional paper, it can save a lot of forest resources for the society, and reduce the secondary pollution in the process of papermaking; From the perspective of replacing some traditional plastic packaging, it can save a lot of strategic oil resources for the country (2.3 tons of oil can be saved for every ton used). The products can be degraded after use, and will not cause secondary white pollution. The stone paper industry, a new environmental protection material, has a wide range of materials, and there is a wide space for product upgrading, technology upgrading and application expansion. It is a sunrise industry with strong vitality.
2. Product features:
The production process of stone paper is simple; Large investment, high output and low energy consumption; Not using plant fiber and not cutting down trees can save a lot of wood and protect the natural ecology; It does not need to add strong acid, alkali, bleach and other chemical raw materials, and does not discharge waste water, waste residue and toxic and harmful gases. It is a green environmental protection product. The product has the characteristics of good mechanical performance, waterproof, moisture-proof, moth proof, folding resistance, tear resistance, oil resistance, non-toxic, tasteless, pollution-free, stable geometric size, high printing clarity, good effect, and can be naturally degraded into powder and return to nature after use.
3. Product category:
Class I: degradable environmental protection packaging materials series products. This product is mainly used to replace the traditional plastic packaging products; There are mainly two series of industrial packaging materials and living packaging materials. Among them, industrial packaging materials include: dust covers and protective covers for electronics, household appliances, industrial instruments and equipment, and living packaging materials include: medium packaging bags, shopping bags, garbage bags, roll bags and other products used in daily life. Such products have strong social value and market advantages. Social value lies in: 1. The product has photodegradation, oxidative degradation and biodegradation properties. Long term use can fundamentally solve the problem of "white pollution" that increasingly oppresses mother earth; 2. Due to the large use of calcium carbonate, each ton of environmentally friendly packaging materials can save 2.3 tons of oil resources for the country. The market advantage is that consumers not only bear the responsibility of social environmental protection, but also save 15% - 30% of the use cost.
Class II: environmental protection stone wall paper series products. Due to the advantages of raw materials, production technology, process flow and so on, stone paper wallpaper product is a kind of wall paper close to zero benzene and zero formaldehyde. The product has no harmful substances such as heavy metals, no odor, moisture-proof, flame-retardant and antibacterial functional characteristics, and has made a major breakthrough in health and environmental protection! At the same time, due to the huge cost advantage of raw materials and the promotion of the new "one-stop sales service center" direct sales model, the price of environmentally friendly wall paper is 20% to 50% lower than that of similar products in the market
Category III: environmental protection stone paper series products. It is mainly used to replace some traditional cultural paper, packaging paper, special paper and other products; This kind of products has changed the traditional papermaking technology. It does not use wood pulp, does not need to cut down trees, does not discharge strong acids, strong alkalis and other chemicals, and does not discharge waste water.
4. Meaning:
The contribution of stone paper to the environment: Stone paper is made by completely dissolving a large amount of inorganic mineral powder into a small amount of non-toxic resin. The process is environmentally friendly. After use, it can be brittle and return to the earth by itself. If the recycled paper is sent to the incinerator for incineration, a small amount of non-toxic and harmless resin will not produce black smoke or toxic gas after incineration, and the remaining inorganic mineral powder can also return to the earth and nature.
5. Comparison:
The new wood pulp free stone paper takes into account many factors such as environmental protection cost, raw materials, processability, market acceptance, and future. Although it cannot fully replace the market of traditional paper, the printing quality of stone paper is similar to that of traditional paper, and it has the physical characteristics of synthetic paper. The following compares the differences between wood pulp paper, synthetic paper, and lithopaper.
Recyclable: Stone paper products can be recycled through plastic products after use. After collection, they can be crushed, extruded and granulated into good additives for PE plastic processing. They can produce colored plastic bags, flower pots, plastic barrels, etc. After being used, stone paper is treated as garbage and sent to the incinerator for combustion. Because it contains a large amount of stone powder and a small amount of non-toxic resin, only non-toxic resin can be burned. When the resin burns, the stone powder will pulverize to promote the contact between the resin and the air, and accelerate the complete combustion of the resin. Therefore, black smoke will not be produced due to anoxic smoldering during the combustion. After the combustion of the non-toxic resin, there is no toxic waste gas, and the emission of carbon dioxide is small, which can slow down the warming of the earth. After being used, stone paper is discarded outdoors, and it will automatically embrittle into a broken eggshell shape under the sunlight for about six months, returning to nature (if the paper is placed indoors, there is no UV damage in the sunlight, and the resin will not embrittle).
Protection of water resources and energy conservation: Stone paper has a strong awareness of environmental protection. Stone paper products do not need to be washed with water at all, nor do they need strong acids, alkalis and bleaches. Therefore, there is no problem of wastewater discharge, and water resources such as rivers and seas are not polluted. In addition, the energy consumption in the process is lower than that of traditional wood pulp papermaking, which helps to improve global warming caused by carbon dioxide (CO2).
Product use of stone paper (pe+ calcium carbonate) unidirectional stretching extrusion production line: the product has an extremely wide range of applications, and can be applied to disposable household consumables, such as garbage bags, shopping bags, food bags, dense bags, lunch boxes, foot gloves, tablecloths, raincoats, dust covers, etc; It can also be applied to cultural paper, such as printing paper, writing paper, advertising decoration paper, Dorian paper, coated paper, film paper, picture paper, stickers, typing paper, envelope paper, grazin paper, newsprint, etc; It can also be used in building materials decoration, such as decorative wallpaper; It can also be used in industrial packaging and other fields, such as fertilizer bags, cement bags, rice flour bags, clothing bags, all kinds of handbags, cartons and cartons, etc; It can also be applied to special paper, such as field operation paper, underwater operation paper, mining operation paper, special paper, etc. It can be said that the application field is very wide, and with the continuous maturity and upgrading of stone papermaking technology, the application field will be larger. The cost of stone paper products is 20% - 30% lower than that of alternative products, which has strong competitiveness and a very promising market prospect. Now, stone paper has been widely used in wall wallpaper, book printing, food packaging, handbags, maps, posters, cards, etc. it has good properties such as environmental degradation, oil resistance, water resistance, mold resistance, insect resistance, tear resistance and so on.
