The grey board paper and black paper board mill all over the country were similar, the price was up 400-500 yuan / ton, and the price of grey board paper and black cardboard has gone through the highest price after the price rise. According to insiders, the price has risen, on the one hand, because of the excessive gap in domestic waste paper, the Sino US trade war, and the state tightening to the ocean. The domestic waste paper is not coming in, causing the domestic waste paper to rise one day and some paper factories to stop production, which leads to the shortage of the original paper. On the other hand, the large paper mills are desperately plling the price of waste paper,causing the price of the original paper to remain high.
