Coated paper and synthetic paper have obvious differences in many aspects, these differences are mainly reflected in the material, characteristics, uses and environmental protection.
Material and characteristics
Coated paper:
Material: Coated paper is a lightweight, high-strength, high-gloss white paper made mainly from high-quality wood pulp. Its surface will be processed, coated with a white coating made of calcium carbonate or white clay and adhesive, and then dried and pressed to make.
Features: Coated paper surface smooth and flat, high smoothness, good gloss, thin and uniform coating, no bubbles. It has good water resistance and tensile properties, and the absorption and reception of ink are also very good. In addition, the coated paper also has a certain sense of three-dimensional and texture, feel relatively hard.
Synthetic paper:
Material: Synthetic paper is a kind of paper synthesized with chemical raw materials, generally with hydrocarbon chemical raw materials such as polyethylene, polypropylene and so on as the main raw materials, and then add some additives made. The surface is usually covered by high-density polyethylene, the middle layer is a polyethylene film mixed with pulp, and the bottom layer is a pulp layer.
Characteristics: The synthetic paper is soft, strong tensile force, good water resistance, light resistance to cold and heat, and can resist the corrosion of chemical substances. It also has the characteristics of non-toxic, pollution-free, good permeability and so on. In addition, the surface of synthetic paper is smooth and flat, but it does not absorb ink like natural fiber paper, so special attention needs to be paid to controlling the surface properties and the adhesion of the ink when printing.
use
Coated paper: Because of its excellent printing performance, coated paper is often used to print high-grade printed matter, such as advertising, landscape paintings, exquisite calendars, people photography and so on. In addition, it can also be used to print book covers, illustrations, etc.
Synthetic paper: Because of its unique properties, synthetic paper is widely used in high-end art, maps, albums, high-end books and other printing. At the same time, it is also suitable for making fishery paper, nautical charts, water-resistant newspapers, record sealing bags, commodity labels, outdoor advertising, business cards and so on.
Environmental protection property
Coated paper: As a printing material made of high-quality wood pulp, coated paper has good biodegradability, so it performs well in terms of environmental protection.
Synthetic paper: Although the production process of synthetic paper is pollution-free, and the product can be recycled after use, the plastic materials such as polyethylene are not degradable. Therefore, from the perspective of long-term environmental protection, the environmental protection of synthetic paper may be slightly worse than that of coated paper.
In summary, coated paper and synthetic paper have obvious differences in material, characteristics, uses and environmental protection. When choosing which paper to use, it is necessary to make comprehensive consideration according to the specific needs and scenarios.
