Paper Density §

Group: 4 #group-4

Relations §

• Printability: The printability or ink receptivity of paper is affected by its density, surface roughness, and porosity.
• Folding Endurance: The folding endurance or ability of paper to withstand repeated folding is related to its density and fiber composition.
• Dimensional Stability: The dimensional stability or resistance to shrinkage or expansion of paper is influenced by its density and fiber composition.
• Stiffness: The stiffness or rigidity of paper is related to its density, with denser papers generally being stiffer.
• Basis Weight: Basis weight is another term for grammage, which is a measure of the density or mass per unit area of paper.
• Fold Endurance: Higher density paper tends to have better fold endurance, as the fibers are more tightly packed and can better distribute stress during folding.
• Tensile Strength: The tensile strength or breaking strength of paper is affected by its density and the strength of the fiber network.
• Surface Roughness: The surface roughness of paper can be influenced by its density and the compressibility of the fibers.
• Opacity: The opacity or transparency of paper is affected by its density, with denser papers generally being more opaque.
• Filler Content: The amount of fillers like clay or calcium carbonate added to the paper can increase its density.
• Compressibility: The compressibility of paper fibers during the papermaking process can affect the final density of the paper.
• Caliper: Caliper is the thickness of paper, which is influenced by its density and compressibility.
• Moisture Content: The moisture content of paper can affect its density, with higher moisture levels generally resulting in lower density.
• Environmental Impact: The density of paper can influence its environmental impact, as denser papers may require more resources and energy to produce.
• Brightness: The brightness or reflectance of paper can be influenced by its density and the types of fibers and fillers used.
• Pulp Type: The type of pulp used, such as chemical or mechanical pulp, can influence the density of the resulting paper.
• Fiber Composition: The types of fibers used in papermaking, such as wood pulp or recycled fibers, can affect the density of the final paper product.
• Grammage: Grammage, or basis weight, is a measure of the density or mass per unit area of paper, directly related to its density.
• Tear Resistance: The tear resistance of paper is influenced by its density and the strength of the fiber bonds.
• Porosity: The porosity or air permeability of paper is related to its density, with denser papers generally having lower porosity.
