[Chinese Packaging Network News] In Baishan Hongqiao Paper Co., Ltd., the new production of fresh fruit and vegetable wrapping paper, can make the preservation of fruits and vegetables from 8 days to half a month, nearly doubled the time, and production costs No increase. The demand for products is not satisfied, and the price has increased by 10%. An ordinary wrapping paper, after adding the elements of science and technology, will glow with vitality and vitality. Li Lin, deputy general manager of Hongqiao Paper Co., Ltd. pointed out one of the mysteries: adding a carton of diatomaceous earth can extend the freshness of fruits by one week.
By the end of 2013, Hongqiao Paper had completed a total investment of 271 million yuan and added an annual production capacity of 100,000 tons of high-strength corrugated paper production lines (including a set of ancillary facilities such as papermaking wastewater treatment). The production line adopts advanced facilities such as hydraulic headboxes and double stacking nets, which can fully guarantee the quality of the fibers, ensure the formation of the paper, and increase the strength of the paper. The UNO dryer was selected in the front section of the paper machine to ensure the production efficiency and product quality of low-quantitative paper. This is the only company in the country that can make use of diatomaceous earth for papermaking. Through pulping, forming, drying and other processes, it will “land”. Made of fruit wrap. In order to meet the requirements of environmental protection, papermaking wastewater is first treated by the papermaking wastewater treatment plant. After reaching the requirements, it will enter the urban sewage treatment plant for reprocessing, reaching the standard returning paper mill for recycling, and a virtuous circle of water resources will be formed.
The third grade diatomite abandoned by others became a “treasure” for Hongqiao Paper Company in Northeast Asia. The company continued to increase scientific and technological research and development efforts, making full use of the diatomite-rich resources in Baishan City, Jilin Province, adopting new technologies and new processes, and using diatomite, peripheral waste paper, and purchased whiteboard paper as raw materials to develop new types of packaging paper. - Diatomaceous earth white paper. The product has characteristics of large porosity, strong adsorption, small bulk density, heat and sound absorption, stable chemical properties, non-toxic and tasteless, and can be used for special industrial paper packaging, such as food health product packaging, refrigerator deodorant paper, etc. The characteristics of printing paper and production operability have broad market prospects, which greatly enhance the competitiveness of enterprises.
"Using 'earth' papermaking saves wood and does not produce harmful substances such as formaldehyde," said Li Lin. Next year, Hongqiao Paper will invest 100 million yuan to add a 100,000 tons per year diatomaceous earth whiteboard production line. After the project is put into production, it can increase annual sales income by 300 million yuan and profits and taxes by 30 million yuan.
