WebMar 9, 2024 · The differences between filter paper and normal paper can be summarized as follows. Porosity: Filter paper has a specific porosity that allows it to filter out certain particles, while normal paper does not have this property. Pore size: The pore size of filter paper is carefully controlled, while normal paper has a random distribution of pores. WebPaper is a highly porous material and contains as much as 70% air. Porosity is a highly critical factor in Printing Paper, Laminating Paper, Filter Paper, Cigarette Paper, Bag Paper, Anti-tarnish Paper and Label Paper. Porosity is the measurement of the total connecting air voids, both vertical and horizontal, that exists in a sheet.
