PE Stone Paper Sheet Line includes three parts: material processing (granulation), salivation stretching (paper making), and coating (paper surface treatment).
Introduction To Stone Paper
Stone paper is a new type of material between paper and plastic. It can not only replace part of the traditional functional paper, professional paper but also replace most of the traditional plastic packaging.
Stone paper has the characteristics of low cost and controllable degradation, which can save users a lot of cost without causing pollution. From the perspective of replacing some of the traditional paper, stone paper can save a lot of forest resources for the society, and can also reduce the secondary pollution generated in the papermaking process;
From the perspective of replacing some of the traditional plastic packaging materials, stone paper can save a lot of strategic resource oil for the country (each ton used can save 2.3 tons of oil), the product can be degraded after use, and will not cause secondary white pollution.
The environmental protection new material stone-paper industry has a wide range of materials, and the space for product upgrades, technology upgrades, and application areas is very broad. It is a sunrise industry with strong vitality.
The Characteristics Of Stone Paper
- The stone paper production process is simple; the investment is large, the output is high, and the energy consumption is low;
- No plant fiber and no felling of trees can save a lot of wood and protect the natural ecology;
- It does not need to add chemical raw materials such as strong acid, strong alkali, bleaching agent, etc., and does not discharge wastewater, waste residue and toxic and harmful gases. It is a green and environmentally friendly product.
The product has good mechanical properties, water resistance, moisture resistance, moth resistance, folding resistance, tear resistance, oil resistance, non-toxic, odorless, non-polluting, stable geometric dimensions, high printing definition, good effects, and can be naturally degraded into powder after being discarded. Nature and other characteristics.
Types Of Stone Paper
The first category: a series of biodegradable environmentally friendly packaging materials, which are mainly used to replace traditional plastic packaging products.
The series of biodegradable environmentally friendly packaging materials mainly include two series of industrial packaging materials and living packaging materials.
Industrial packaging materials include dust-proof covers and protective covers for products such as electronics, home appliances, and industrial instruments and equipment;
Life packaging materials include all kinds of packaging bags, shopping bags, garbage bags and rolling bags used in daily life. Such products have very strong social value and market advantages.
The second category: environmental protection stone wallpaper series products.
Due to the advantages of raw materials, production technology, process flow, etc., the stone paper wallpaper product is a wallpaper with close to zero benzene and zero formaldehyde in the world. The product has the functions of no harmful substances such as heavy metals, no peculiar smell, moisture-proof, flame-retardant and antibacterial. characteristic.
The third category: environmentally friendly stone paper products. Mainly used to replace some traditional cultural paper, packaging paper and special paper products; this type of product changes the traditional papermaking technology, does not use the wood pulp, does not need to cut trees, does not emit strong acids, alkalis and other chemical substances. No wastewater is discharged.
The Meaning Of Stone Paper
The contribution of the stone paper to the environment: stone paper is a large amount of inorganic mineral powder completely dissolved in a small amount of non-toxic resin, the process is environmentally friendly, and it can embrittle itself and return to the earth after use.
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 poisonous gas after incineration, and the remaining inorganic mineral powder can also return to the earth and nature.
Uses Of PE Stone Paper Sheet Line Products
- Disposable daily consumables, such as garbage bags, shopping bags, food bags, compact bags, lunch boxes, foot gloves, tablecloths, raincoats, dust covers, etc.;
- Cultural paper, such as printing paper, writing paper, advertising decoration paper, forest paper, coated paper, film paper, drawing paper, poster stickers, typing paper, postal envelope paper, cigarette paper, glassine paper, newsprint, etc. ；
- Building materials decoration, such as decorative wallpaper, etc.;
- Industrial packaging, such as fertilizer bags, cement bags, rice flour bags, clothing bags, various handbags, cartons, and cartons, etc.;
- Special paper, such as paper for fieldwork, paper for underwater work, paper for mine work, special paper for military use.
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. It is extremely competitive and has 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 protection, biodegradability, oil resistance, water resistance, mildew resistance, insect resistance, and tear resistance.
Stone paper is divided into PP and PE. According to the purpose of the paper, the material and paper-making method are selected.
Processing methods are divided into:
- Casting stone paper/synthetic paper production line;
- Unidirectional stretch stone paper/synthetic paper production line;
- Biaxially oriented stone paper/synthetic paper production line.
Performance ＆ Advantages
Stone paper production equipment adopts casting&calendaring process technology:
compounding, mixing, extrusion to produce the special masterbatch, then through the extruder, calendaring, stretching, cooling, surface treatment, coating, cutting, and winding to produce origin paper. Its features for high efficiency, good quality, low-cost production, smooth surface paper, especially used to print high-grade albums and book covers, etc.
Feature & application Stone paper features:
The stone paper production process is easy, high output, lower power consumption; not use plant fiber、not cut trees, save lots of wood, protect the natural environment; Don’t need to add strong acid、strong alkali、bleaching agent, etc. Chemical material, don’t drainage waste water、waste residue and toxic and harmful air, that’s the green environmental product. Product with good mechanical performance、waterproof、moisture proof、moth-proofing, folding, tear-resistant, oil-resistant, non-toxic, tasteless, no pollution, stable geometry size, high printing resolution, good effect, can be natural degradation after with abandon for powder characteristics of return to nature, is widely used in gift packaging, pharmaceutical packaging, office supplies, decorative materials, and other areas of the printing products.
