It is a material that is made up of a very thin sheet, which is made from cellulose pulp (a material made from the wood of trees), which is nothing more than a set of fibers of plant origin Shredded, which to be transformed into paper must go through a series of processes that begin with the soaking of said fibers in water, then they are bleached, then they dry, they harden certain chemicals are added to give them some special characteristics. These fibers are joined to each other by so-called hydrogen bonds.
In ancient times, before paper existed, Chinese people used slats of wood and bamboo to capture their writing, but these techniques were not very feasible, since they complicated the task of writing, in addition to being a problem when wanting to save for posterity to these writings. Later, with the appearance of the hair brush, several attempts were made to make paper from different materials such as rice, silk, straw and cotton, despite this, the first process where paper was made from from the bark of a tree is attributed to Cai Lun who was an adviser to the emperor of the eastern Han dynasty.
The traditional elaboration to make paper consists of placing a set of fibers to soak in water, to then be dried in what is known as a sieve, all this with the purpose that a layer of fibers joined randomly is formed, subsequently they finish draining the fibers using the drying and pressure method, resulting in a very thin layer of interlaced fibers.
At present, the paper market is quite large and diverse, offering a large number of types of paper which are made to adjust as much as possible to each of the consumer demands. What makes the difference between one type of paper and another is:
- Durability: property to remain through the years.
- Stability: that maintains the correct dimensions regardless of the different environmental conditions where it is.
- Resilience: property that allows the paper to recover its shape after it has been modified.
