2021-03-23

Paper can used for writing, printing, painting or packaging.  Paper bag, card, shopping bag, book, notes, wraping paper ext. all can't live with out paper.

It is generally made of an aqueous suspension of plant fibers that has been pulped, interlaced on the net, initially dehydrated, and then compressed and dried.


China is the first country in the world to invent paper. According to archaeological findings, during the Western Han Dynasty (206 BC to 8 BC), my country already had hemp fiber paper, but it was difficult to popularize because of its rough texture, small quantity and high cost.

In the first year of Yuanxing in the Eastern Han Dynasty (105 years), Cai Lun invented writing paper made of rags, fishing nets, and bark on the basis of former artificial paper, which provided necessary conditions for later copying, rubbing and engraving. . Since then, paper has been promoted and used as the main writing material in China. Since then, paper made of bamboo and grass fibers has appeared, and the quality of the paper has been continuously improved.

Chinese papermaking technology spread to Central Asia and Arabia in the 8th century, and then gradually spread to Europe. Until the 18th century, papermaking methods remained basically unchanged. Since the 19th century, several pulping methods using wood as raw materials have been gradually developed. From then on, the paper industry no longer depends on raw materials such as rags and can be mass-produced. Modern papermaking procedures are not much different from traditional Chinese papermaking techniques except for individual processes and chemical raw materials.

Papermaking is one of the four great inventions in ancient China. The invention and dissemination of papermaking have greatly reduced the cost of text carriers, and the popularization of knowledge among civilians has been realized, which has greatly promoted the development of world technology, culture and economy.
