It is understood that stone paper is based on limestone mineral resources with large reserves and wide distribution as the main raw material. After a special process, it is made of environmentally friendly paper with the same writing and printing effect as plant fiber paper. Because it does not consume plants in the production process Fiber and no trees are cut down, so stone paper has a very cost advantage. According to the introduction of the staff of stone paper production enterprises, the cost of stone paper is 20% to 30% lower than that of traditional paper, and the market advantage is obvious.
According to the staff of printing and packaging companies that have used stone paper for production, because stone paper does not contain wood fiber, the unit density of paper is higher. Compared with ordinary paper, the weight of paper of the same area and thickness increases by about 30%. Calculated at a price of 9,000 yuan/ton sold to a printing and packaging factory, the amount of paper actually obtained is equivalent to a price of 12,000 yuan/ton compared with traditional paper, and the price advantage is not obvious.
Comment: The main raw material of stone paper comes from limestone. Compared with the traditional paper whose main raw material is plant fiber and the price is rising, its cost must have certain advantages, but the related technology is not mature enough, market monopoly and price positioning are not clear, etc. The reason is that the current market price advantage has not fully emerged. However, with the continuous maturity of related technologies and the breaking of market monopoly, the price of stone paper will definitely decline.
