Paper

Paper (/ˈpeɪpər/; from Latin papyrus, which comes from the Greek πάπυρος, the word for the Cyperus papyrus plant) is a thin material produced by pressing together moist fibres of cellulose pulp derived from wood, rags, or grasses, and drying them into flexible sheets.

History

Paper was first invented in ancient China in the 2nd century BC during the Han Dynasty and spread slowly to the west via the Silk Road. Papermaking and manufacturing in Europe was established by the Arabs in the Iberian Peninsula by the 12th century.

Production

Paper is produced by pulping wood chips under mechanical or chemical methods to separate cellulose fibres. These fibres are then bleached and then formed into a sheet by draining the water through a fine mesh leaving the fibre evenly distributed on the surface. The remaining water is removed by pressing and drying.

Types of Paper

There are many types of paper, including:

Environmental Impact
