Shanghai Guangfa Paper Mill Successfully Produced Moisture-proof Corrugated Paper

Shanghai Guangfa Paper Mill is specialized in the production of corrugated paper companies. The main papermaking raw materials come from imported American waste, daily waste and social recycling old cartons, and carton factory paper, with an annual output of 7000 tons of corrugated paper. The corrugated paper of this factory is of good quality, its physical properties are up to the national standards, its moisture content is around 8%, and it is highly favored by users of carton boxes in Shanghai, and its products are in short supply. Last year, it also invested 8 million yuan to add a 2362-type 2.4 m-watt webbing machine and water treatment equipment. With an annual output of 15,000 tons of corrugated paper, it has been put into production to meet the needs of users.
Based on the existing corrugated base paper, the plant cooperated with the University of Shanghai for Science and Technology in the development of moisture-proof corrugated base paper. After repeated trial production, the company successfully trialed the moisture-proof corrugated base paper in early July this year. Under the guidance of a professor from the University of Shanghai for Science and Technology, several chemical additives were added to the papermaking raw materials to increase the degree of drying and moisture resistance, and to solve the problem of corrugated paper playing a damp-proof role in a humid climate or in a cold store. This moisture-proof corrugated base paper can resist moisture absorption into the corrugated base paper. Applicable to food, fruits, vegetables into the cold, also applies to product moisture. At present, all regions are developing honeycomb paperboard. This moisture-proof corrugated base paper is suitable for making honeycomb paperboard cores, which can prevent the moisture of export paper trays from affecting the quality of products. The moisture-proof corrugated paper is the first in the country. The use of moisture-proof corrugated base papers greatly improves the quality of cartons. Use, there is a broad prospect for development.
