Bleached Paper - What is bleached paper?

Answer:

Paper that has been treated with chemicals in order to artificially lighten the colour of the paper or increase its brightness. Bleaching is done during the paper manufacturing process while the paper is still in a pulp form. Bleaching can also help to prevent discolouration during storage, stop yellowing during exposure to sunlight, and maintain the strength of the material during the rest of the manufacturing process. Bleaching can also be done to a variety of other materials.
