Paper Calendering Machine


Paper calendering machine is used for calendering the paper or paperboard with a certain moisture to improve the paper smoothness and gloss for printing and writing, as well as of a consistent thickness for capacitors that use paper as their dielectric membrane. So what’s the effect of paper calendering machine on paper quality?

Calender Machine Effect On Paper Quality

1. The effect on paper thickness and permeability: The thickness is reduced and the air permeability is reduced.

2. The effect on paper smoothness: Paper smoothness is improved.

3. The effect on paper gloss: Improve the line pressure, increase the filler content, improve the paper into calendering moisture, and increase the calender roller surface temperature, help to improve the gloss. But the increase of transparency make the reduce of whiteness measured by the reflection method.

4. The effect on strength:

a. Tensile strength: The roller heating, can reduce the paper strength; Reduce residual pressure, can further improve the paper strength.

b. Tearability: Reduced after calendering.

c. Elongation: The longitudinal elongation slightly reduced after calendering.

d. Bursting strength: Bursting reduced after calendering.
