The paper manufacturing industry is concerned with pulp
paperboard making and paper for printing purpose. Both virgin and recycled-fibre pulping
and paper manufacturing technology is used for the process.
First we would have a look on the raw materials utilised by
the pulp and paper companies, to manufacture paper and paperboard;
- Fiber: Wood and Bamboo are the ideal options for paper making pulp creation. The organic glue ligitin is a complex one that binds cellulose fibers together. Non-wood fibers of kenaf, flax, wheat straw and sugar cane fiber are also used in pulp making.
- Energy: Pulp and paperboard making equipment runs on steam and electricity depending on the energy resources that are easily available.
- Chemicals: Sulphite pulping with Kraft is used as chemicals as well as caustic soda and chlorine with oxygen-based chemical bleaches are essential for the pulp and paper making industry.
- Water: Water is one among most exclusive raw materials for paper manufacturing by the pulp and paper companies.
Now step into the world of paper making techniques;
- The cellulose fibers of wood, waste paper recovered along with plants in making paper.
- Foremost the raw material is collected for making the pulp; this pulp is used for fiber production.
- Then the process of bleaching is done, if white paper is required, as the pulp is bit dull for white paper.
- Then the real process of paper making is started.
- Application of bleach brightens the pulp, then glue and chemicals are mixed with the pulp to make it slurry.
- Using the products of manufacturers of paper making machinery, the pulp is pressed, dried and then rolled into huge rolls.
- The end product is then cut into desired rolls of paper and sent to the market for selling.
