August is divided into the first half of the month and the second half of the month. LLDPE East China market rose in the first half of the month and fell in the second half of the month. It was greatly affected by Liansu futures during the month. Although the overall focus moved upward, it was not much compared with the beginning of the month. LDPE East China market adjusted sideways in the first half of the month and rose in the second half of the month, mainly due to tight market supply, obvious market speculation atmosphere and sharp price rise. Due to high supply pressure, insufficient follow-up of downstream demand and contradiction between market supply and demand, HDPE fell unchanged in August, decreased significantly in the first half of the month and continued to be weak in the second half of the month.

Due to the rapid rise of high-pressure prices in the early stage, the downstream has limited ability to accept high prices, has a cautious attitude, and the market transaction atmosphere is poor. At the end of the month, there was a correction in the price of polyethylene. In the future, in September, agricultural film ushered in the peak demand season, and the demand is expected to increase. However, in terms of supply, the overall supply pressure of the market is large. In general, it is expected that the PE spot market will fall first and then rise in September.
