HOW IS PAPER MADE
Once the wood is made this is sent to the factory for its proccesing.
This proccess can be carried out by one of those methods
Mechanical Method
In mechanical processing, the machines grind the chips into pulp. The paper that is obtained is not as strong as chemical one is.
This kind of paper is usually used for telephone and press directory paper
Chemical Method
The chemical process is the most common in which different methods are used to convert wood into pulp with selective products.
Soft wood planks like pine have longer fibers and give a stronger paper
Hard wood fibers are shorter, but tend to serve better as printing and writing papers.
Once the pulp is done they must remove the liquid part of this and dry it, when the paper has approximately 50% of the water removed, it is heated to get the water content between 5 and 8%
Recycled and Natural peper
Recycled
it is paper used previously, which has been given a new use.
Natural paper is that which is extracted directly from the forests and does not need so many chemicals to clean them.
