In recent years, Vietnam's paper industry has been developing strongly, meeting the increasing demands of consumers. One of the new trends of the paper industry is producing low-density paper. Low-density printing paper is highly porous, lightweight, low volume, natural whiteness, and is environmentally friendly. In order to meet the demand for producing low-dumpling paper, the Institute of Paper Industry and Cellua Industry has implemented the topic "Completing technology and equipment producing low-specific printed paper". The topic has achieved important results, contributing to the sustainable development of Vietnam's paper industry.

The trend of using low-specific print paper:

Today, Vietnamese consumers are increasingly interested in cultural paper products that are beneficial to health and environmentally friendly. Low-density printing paper with highly porous, lightweight, low volume, and natural whiteness meets this demand.

Low-density paper is a paper with lower density than conventional paper, often used in printing books. The raw materials for producing low-density paper are often used mainly as mechanical powder such as grinding wood pulp, BCMP powder, BCTMP powder, APMP powder, and part of bleaching chemical powder.

In addition to raw materials, factors that directly affect the quality of low-volume paper also have accessories, fillers, and grinding modes.

Researching the technology of producing low-density printing paper:

In 2017, the Paper Industry and Cellulino Institute was assigned by the Ministry of Industry and Trade to implement the topic "Researching the technology of producing low-volume printed paper" with the goal of establishing the process of producing low-volume printed paper technology for printing books.
