Paper Porosity §

Group: 4 #group-4

Relations §

• Printing Quality: Paper porosity affects the ink absorption and print quality on the paper surface.
• Air Permeability: Air permeability is a measure of the porosity and openness of the paper structure.
• Surface Roughness: The surface roughness of paper is related to its porosity and fiber structure.
• Liquid Absorption: The porosity of paper influences its ability to absorb and hold liquids.
• Fold Endurance: Porous paper can be more susceptible to weakening and tearing during folding, negatively impacting fold endurance.
• Filler Content: The addition of fillers like clay or calcium carbonate can affect the porosity of paper by filling in the pores between fibers.
• Packaging Performance: The porosity of paper can impact its performance in packaging applications, such as moisture and gas barrier properties.
• Pulp Refining: The degree of pulp refining affects the fiber structure and porosity of the resulting paper.
• Fiber Structure: Paper porosity is influenced by the structure and arrangement of fibers in the paper sheet.
• Sizing Agents: Sizing agents added to paper can modify the porosity and liquid absorption properties.
