Volumetric paper

-

Volumetric paper - is a special type of offset paper with a significant volume (over 1.3). The volume paper structure is loose to increase the thickness of the paper. This paper usually has a basis weight of 60-100 g / m³ and a volume of 1.5-2.2 cm³ / g. Production technology

Volumetric paper is currently produced from bleached cellulose, a method of injecting paper pulp between paper machine screens. Once the web is formed, the paper is surface-glued and, at the end, smoothed or satin. In order to increase whiteness, optical brighteners are added to the pulp.

Formerly, volumetric papers were obtained by the selection of suitable raw materials - mostly from a blend of cellulose obtained from esparto grass and wood cellulose - mostly coniferous. Application

Volumetric paper is often used to produce books and brochures that, despite the small number of pages, look great.

An important use is also the production of publishing series that have a fixed, constant thickness of the back. By selecting the appropriate paper volume, you can achieve the book's thickness without changing the number of pages.

Another application is mail advertising, where using this type of paper reduces shipping costs while maintaining a certain paper thickness. Bibliography Stefan Jakucewicz: Paper in printing. Warsaw: The Invention, 1999, p. 156-157. ISBN 83-911435-0-3.
