The Process of Making a Good Quality Paper and the Importance of Testing Them

At the point when is the last time you utilized something that was made out of paper? Most likely not particularly lengthy time-frame back in fact. In the present time where individuals are endeavoring to have paperless workplaces, how regularly that is valid actually?

It is hard to imagine a paperless world or office which does not use a single piece of paper, as we use it for so many different things. In fact the two most important things for which we use paper is for printing and writing. Paper is probably one of the most important inventions by man, and for this we need to have wood pulp to thank it for all.

The use of paper states back to the ancient Egyptians. It was at that time called papyrus. Since those days the production of paper has come a long way. The process in which paper is made from pulp is discussed below in brief.

How Paper is made from Pulp?

Although paper is made from pulp, there are many that are made from recycled paper, special cloth and sometimes from grass. However, most of the paper is made from wood.

There are farms that are particularly set up to plant trees for the sole motivation behind delivering paper items and they grow two different types for these items, softwood and hardwood. The main reason for growing these two types of tress is because these woods will make a very good quality of paper.  Few other common type of trees grown for paper is spurce and pine. These trees are well maintained until they reach the right age and after that they are cut down and bought in the paper industry to make and produce paper.

Paper industry uses various paper making instruments such as pulp testing equipments like beating & freeness tester, wood dust maker, wood chipper, rapid sheet dryer etc.


Process of Making Paper from Pulp

At first the bark of the tree is removed and is washed. Once it has been washed then it is chopped into small blocks. The next thing that is done is testing of wood for any type of particles that might be metallic. This is done by using a strong magnet to run over the blocks of wood and then they make sure all meal is removed from it.

Once the wood has been deemed free of all non wood materials the next step is processed. This step is done to remove the pulp from the wood. There are several different ways to do this. One way is by using grinder, another way is to extract it with the help of a digester. Many a time chemicals are used to extract it from wood blocks. Even steam and water is also used to help remove it from wood. The pulp contains wood fibers along with cellulose which is important for the production of paper.

Once the cellulose and all of the fibers are ready the next step will begin. In the next step the bleaching of it is done to purify it before the paper is actually produced. After it has been purified the actual making of the paper is begin.

Paper Quality Testing

Paper has always been a favorite alternative of plastic. There are many industries where plastic is not fit for use in such industries paper fills the space. As plastic packaging of many products would increase the cost, thus in such places paper packaging is done to complete the job. Apart from this, paper packaging is widely used as toilet rolls, kitchen towels, for making paper cups etc. Paper has countless applications in diverse industries, but how can you decide whether it is suitable for a particular application?

Quality analysis is the exact answer for this question. Testing is an imperative and qualitative procedure. It is physical process that involves laboratory experiments and personal evolutions. Another important factor is documentation which includes standard test methods, test results in report format, videos, etc. The testing of Paper and packaging comprise of the assurance of different qualities of paper and distinctive properties required with packaging. Paper and packaging testing is done to ensure the safety and quality of products during storage and transportation.

Various industry standard organizations have ruled out different testing procedures as per the industrial requirements. The properties of materials vary as per the composition of raw materials.

Use of Bursting Strength Tester: With the digital model of bursting strength tester hydraulic pressure on the paper is applied via a rubber diaphragm.

Moisture Analysis Test: This test is done to know how much moisture a paper absorbs from the surroundings. This test tells the operator about the original moisture content, when it is exposed to a moist environment for predefined time. It also has a scale that measures the weight of the sample paper. Once the weight difference is calculated, it shows the moisture content in the sample.

Measuring of Gloss:  Numerous paper assortments have natural gloss on the surface while other have matte finish. Because of contrast in texture of the surface, the printability shifts and last print has extensive distinction than sample. On the off chance that before printing, the gloss is estimated, it helps in keeping the difference to the minimum. This estimation is imperative while amid printing of limited promotional materials.
