: If bright white paper is needed, the pulp is bleached with chemicals. Brown pulp is left unbleached for products like grocery bags or cardboard. 2. The Forming Stage
: It is more accurate to say paper is "made from wood" rather than "made of wood," as the chemical structure changes entirely during the pulping process.
This is where the liquid pulp begins to take the shape of a solid sheet. dimmi_cose
The wet sheet must have almost all remaining moisture removed to gain strength.
: This slurry is sprayed onto a moving mesh screen at high speed. : If bright white paper is needed, the
: Bark is removed from logs, which are then chopped into small wood chips.
: The paper passes through "calendar" rollers to smooth the surface and ensure uniform thickness. The Forming Stage : It is more accurate
: The finished paper is wound into massive "parent rolls," which are then slit into smaller rolls or cut into standard sizes like A4.
