Modern paper is normally made from wood pulp.[1] Wood is ground up and mixed with water and other chemicals to make a thin liquid called "paper pulp". Paper pulp can be bleached to make paper more white, and dyes can be added to make colored paper. This pulp is pressed into sheets of paper. Printing is often done on paper before the paper is cut into sheets. Newsprint paper (newspaper) comes in a huge roll, and goes through the printing process as one continuous sheet. It is cut by a machine-driven guillotine blade later. Folding comes last, then packing for distribution.
Sometimes paper is made heavier and more glossy (shiny) by adding clay, and by 'milling' it. Milling is done by squeezing the paper through a series of rollers. Sometimes paper is made from used or waste paper: this is recycling.
Not all paper is made from wood. Other kinds of fiber can be used. People still make paper from cotton, linen and hemp for special purposes.
