LWC (Light coatad Paper) is also called low-coated paper. In Taiwan Province, it is called book paper or lightweight coated paper.
This kind of paper is a lower-quantity coated paper. A thin layer of paint (made of calcium carbonate, cationic cations, etc.) is added to the front and back of the base paper and supercalendered to improve its physical properties and printability. The fiber raw material for light weight coated paper is 40% needle bleach chemical pulp and 60% mechanical wood pulp (or TMP, CTMP). This ratio can greatly reduce the production cost. The basis weight is generally 40-50 g/m2, and the coating weight is 6-10 g/m2 per side.
Light weight coated paper is a species that is between coated paper and offset paper. Its color printing effect is comparable to that of coated paper, and it has good opacity and smoothness as well as high gloss. Due to the incorporation of cheap mechanical pulp, its cost is reduced by more than 30% compared to coated paper. In addition, the light coated paper is lighter than coated paper, which can reduce the postage of Airmail, and is very popular among magazines, newspapers, and book publishers in the world or in large-scale distribution. However, light-coated paper has poor durability and is susceptible to brittle yellowing. Therefore, it is suitable for prints that do not require long-term preservation.

Trends, and lightweight coated paper can be very useful in the mail-order business.
In China, the production volume of this product is small, and the quality is not high. In recent years, some companies have been optimistic about this type of paper and increased the investment and development efforts. Such as: Shandong Chenming Group research and development of low-quantity coated paper, the quality reached the international first-class level, to fill the gaps in the country, its good printability and quality won the favor of foreign investors, following the Hong Kong Yuhe company orders, Japan and morning Ming company has signed an export contract of 50,000 tons, only this one can export more than 4000-6000 million US dollars. At present, Shandong Huatai Group East Construction Paper Co., Ltd., which has an annual output capacity of 35,000 tons of light-weight coated paper, is also nearing completion. The machine is supplied by Voith Sulzer, headbox and homogenizer, and Speed ​​Coates coater and soft calendering. The machine has a roll width of 2.64 meters, a speed of 550 meters per minute, a basis weight of 40-80 g/m2, and a raw material of chemical wood pulp. These two companies increase the production of light weight coated paper, which will make papermaking in China New breakthroughs have emerged in the industry.
