How it is made. Before diving right in, it is important to know some background information about trees. Trees are made up of layers. These layers are bark, cambium, phloem, xylem, and heartwood. All of these layers are made up of tiny cellulose strands called fibers; these fibers are stuck together by a natural adhesive called lignin. It is only by harvesting and separating these that we are able to make paper.
Paper is used all over the world. You will find it almost in every moment of your life. It is one of the most important and useful items ever invented by mankind. Paper is also one that a lot of us take for granted.
In making a piece of paper, not all materials are the same though. The trees as the raw material to make papers can be categorized into either hardwood or softwood; which category the wood falls into effects the properties of the product created.
These days, in your daily life, like in schools, offices or other places, you must use papers in any forms. One of the most used ones is notebook paper. Usually, a notebook paper will come in red, blue or grey lines. Those lines are to help writers to maintain a straight line when writing. This does not seem like it should be that hard to visualize and understand. These cold colors are light on the paper and have very low contrast, so they would not interfere with the written and would put less strain on the eyes.
