Synthetic paper/stone paper (PE+CoCO3) longitudinal stretching production line

1. Introduction to Stone Paper Products:
Stone paper is a new type of material between paper and plastic, which can replace traditional functional paper, professional paper, and most traditional plastic packaging materials. And it has the characteristics of low cost and controllable degradation, which can save users a lot of costs without causing pollution. From the perspective of replacing traditional paper, it can save a lot of forest resources for society and reduce secondary pollution generated during the papermaking process; From the perspective of replacing traditional plastic packaging materials, it can save a large amount of strategic resource oil for the country (2.3 tons of oil can be saved for every 1 ton used), and the product can degrade after use without causing secondary white pollution. The environmentally friendly new material stone paper industry has a wide range of materials, and there is a vast space for product upgrades, technological advancements, and expanded application areas. It is a highly vibrant sunrise industry.

2. Product Features:
The production process of stone paper is simple; Large investment, high output, low energy consumption; Not using plant fibers or cutting down trees can save a lot of wood and protect the natural ecology; It does not require the addition of strong acids, strong alkalis, bleaching agents, or other chemical raw materials, and does not discharge wastewater, waste residue, or toxic and harmful gases, making it a green and environmentally friendly product. The product has the characteristics of good mechanical performance, waterproof, moisture-proof, moth proof, folding resistant, tear resistant, oil resistant, non-toxic, odorless, pollution-free, stable geometric dimensions, high printing clarity, good effect, and can naturally degrade into powder and return to nature after use.

3. Product type:
Category 1: Degradable and environmentally friendly packaging material series products. This product is mainly used to replace traditional plastic packaging series products; There are mainly two series of industrial packaging materials and household packaging materials. Industrial packaging materials include dust covers and protective covers for electronic, household appliances, and industrial instruments and equipment products, while household packaging materials include various packaging bags, shopping bags, garbage bags, and roll up bags used in daily life. This type of product has strong social value and market advantages. The 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 extensive use of calcium carbonate, every ton of environmentally friendly packaging material used can save the country 2.3 tons of petroleum resources. The market advantage lies in the fact that consumers not only assume social and environmental responsibilities when using it, but also save 15% to 30% of usage costs.
Category 2: Environmentally friendly stone wall paper series products. Due to advantages in raw materials, production technology, and process flow, stone paper wallpaper products are wall papers that are close to zero benzene and zero formaldehyde in the world. The products have functional characteristics such as no harmful substances such as heavy metals, no odor, moisture resistance, flame retardancy, and antibacterial properties. Their environmental indicators have not only passed the testing and certification of relevant national testing institutions, but also met the testing standards of the European Union, achieving significant breakthroughs 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 and 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
The third category: environmentally friendly stone paper series products. Mainly used to replace some traditional cultural paper, packaging paper, and special paper products; This type of product changes the traditional papermaking process technology, does not use wood pulp, does not require logging, does not discharge strong acids, strong alkalis, and other chemicals, and does not discharge wastewater.

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, with an environmentally friendly manufacturing process. After use, it can self brittle and return to the earth. If the recycled paper is sent to an 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 non wood pulp stone paper considers many factors such as environmental cost, raw materials, processability, market acceptance, and futurism. Although it has not fully replaced 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 differences between wood pulp paper, synthetic paper, and stone paper are compared below.
Recyclable: Stone paper products can be recycled through plastic product recycling channels after use. After collection, they can be crushed, extruded and granulated into good additives for PE plastic processing, which can produce colored plastic bags, flower pots, plastic buckets, etc. When stone paper is used and treated as garbage, it is sent to an 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 burn. When the resin burns, the stone powder will pulverize and promote the contact between the resin and the air, accelerating the complete combustion of the resin. Therefore, black smoke will not be produced during combustion due to lack of oxygen and suffocation. After the non-toxic resin burns, there is no toxic exhaust gas, and the emission of carbon dioxide is minimized, which can slow down the warming of the earth. After being discarded outdoors, the stone paper will automatically become brittle and break into a broken eggshell shape under sunlight for about six months, returning to nature (paper placed indoors will not be damaged by ultraviolet rays in sunlight, and the resin will not become brittle).
Protecting water resources and energy conservation: Stone paper has a strong environmental awareness. The manufacturing of stone paper products does not require washing with water, strong acids, alkalis, or bleaching agents, so there is no problem of wastewater discharge. It does not pollute water resources such as rivers and oceans, and has lower energy consumption in the process compared to traditional wood pulp paper, which helps to improve global warming caused by carbon dioxide (CO2).

Stone paper (PE+calcium carbonate) unidirectional stretching extrusion production line products are widely used in various fields, including disposable household consumables such as garbage bags, shopping bags, food bags, compact 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, poster paper, typing paper, envelope paper, cigarette paper, Grassin paper, news paper, etc; It can also be applied to building material decoration, such as decorating wallpaper, etc; It can also be applied in industrial packaging and other fields, such as fertilizer bags, cement bags, rice and flour bags, clothing bags, various handbags, paper boxes, etc; It can also be applied to special paper materials, such as field work paper, underwater work paper, mining work paper, military special paper, etc. It can be said that the application fields are very extensive, and with the continuous maturity and upgrading of stone papermaking technology, the application fields will become even larger. The cost of stone paper products is 20% -30% lower than alternative products, and they have strong competitiveness, with a very promising market prospect. Nowadays, stone paper has been widely used for wall wallpaper, book printing, food packaging, handbags, maps, posters, cards, etc. It has good properties such as environmental friendliness, biodegradability, oil resistance, waterproofing, mold resistance, insect resistance, and tear resistance.
