(VEN) – Low brightness paper brings about immeasurable benefits. Using high brightness paper with ISO brightness from 80-82 percent can cause eye refraction while low brightness paper with ISO brightness from 73-75 percent is the most suitable with pupil’s eyesight.
Due to consumer preconceptions that the brighter paper is, the better, the position of low brightness paper in the market remains modest. However, recent research has shown the benefits of this kind of low brightness paper.
According to a research project conducted by the Institute of Paper and Xenluylo Industry Co. Ltd under the Vietnam Paper Corporation, low brightness paper with ISO brightness from 73-75 percent has more advantages compared with high brightness paper (ISO brightness from 80-82 percent) in terms of product quality, economic efficiency and environmental friendliness.
More importantly, paper producers can apply traditional bleaching technology and popular ECF, TCF bleaching technologies to produce low brightness paper. This means paper enterprises will not have to change the current entire production technologies.
Low brightness paper also brings about immeasurable benefits, to consumer health. According to Doctor Nguyen Dang Quang, director of the project on studying impacts on pupil’s eyesight implemented by the Education Publishing House and the Military Medical Institute, using high brightness paper with ISO brightness from 80-82 percent can easily cause eye refraction while low brightness paper with ISO brightness from 73-75 percent is the most suitable with pupil’s eyesight.
Obstacles due to consumer psychology
The benefits of low brightness paper have been clearly proved by scientific research. In reality, some paper enterprises have pioneered in producing low brightness paper such as Van Diem and Bai Bang Paper Plants and they have recognized the efficiency in the production of low brightness paper. In the first half of this year, the Vietnam Paper Corporation conducted trial production of 2,200 tonnes of low brightness paper. Statistics showed that the costs on chemicals and other necessary materials to produce low brightness paper have decreased by VND700,000 per tonne.
Despite the obvious benefits, few paper enterprises have taken the risks of producing and trading low brightness paper. Director of Van Diem Paper Plant, Phan Hung said high brightness paper with ISO brightness from 80-85 percent is favored in the market while consumption of low brightness paper remains slow, resulting in capital stagnation and shortage for production.
According to Vu Ngoc Bao, the Chairman of the Vietnam Paper and Pulp Association, the fact that low brightness paper has made little progress is due to customer preconceptions that the brighter the paper is, the better quality. However, this is not true in reality. As for producers and businesses, they still have to follow the supply – demand rule therefore the market share of high brightness paper still dominates.
Vu Ngoc Bao also said to expand the market share for low brightness paper requires state-owned agencies and enterprises working together and consumer support. The benefits of low brightness paper need to be highlighted and firms should be encouraged to produce this kind of paper by offering them preferential taxes within 10 years. As for closely-related bodies such as the Ministry of Education and Training, there should be regulations on the paper brightness used for pupils’ books and notebook./.
