In July, the price of the mainstream market of 50μ jumbo adhesive tape rose from 9600-9800 yuan / ton to 9900-10100 yuan / ton, a cumulative increase of 300 yuan / ton, an increase of 3.09%. In the case of sufficient supply of raw materials, the price increase was mainly due to the fact that PP futures continued to rise at the beginning of the month, which favored the raw material jumbo bopp packing tape market. The raw material jumbo roll cello tape accumulated up 200 yuan/ton; the other raw material butyl acrylate market suffered a serious loss, which was accumulating by the rising price of raw material propylene. Rising 450 yuan / ton; both raw materials rose during the month led to a rebound in the price of the packing tape jumbo roll. The increase in the price of the jumbo bopp packing tape stimulated a small amount of replenishment downstream of the market, and the order of the jumbo roll cello tape manufacturers improved, which also supported the high price after the rise.
