Manufacture
The Product Life Cycle Of Paper
- Logs are converted to wood pulps and are filtered to remove foreign objects.
- The pulp is then put through a pounding, squeezing process called beating.
- Sizing is also added at this point, which affects the way the paper will react with various inks.

- The dried paper is wound onto large reals and smoothed and compacted by going through metal rollers called calenders.
- The paper may go though a vat of sizing material and receive a coating before getting cut into desired size.

- The paper is then pressed between rollers of wool felt ( Remaining water are removed).
