Basic properties The basic properties of any type of paper or board include moisture content grammage thickness (calibre) density bulk and filler content. These are all very important descriptors of the paper. Since paper and board trades mostly on a weight basis, grammage is the link connecting weight of the material to its surface area.

Basic properties
After reading this article you will..
- know the difference between single sheet thickness and bulking thickness.
- know that especially strength properties are influenced by the anisotropy of the machine made paper and thus it very important to mention the test direction of the sample, machine or cross direction.
