Report Summary 1. Report Industry Investment Rating No relevant content provided. 2. Core Views - The polyolefin market is gradually shifting to a pattern of strong supply and demand. New production capacities are being released, and maintenance devices are restarting, leading to a significant increase in production. Although social inventories are accumulating, they are still at a relatively low level compared to the same period. The start - up rate of agricultural film has improved for three consecutive weeks. Attention should be paid to the restocking rhythm [4]. - The PP market maintains a pattern of weak supply and demand. The upstream operating rate has remained at around 77% for six consecutive weeks, and downstream demand is at the transition point between the off - season and peak season. The inventory structure of the upper and middle reaches continues to diverge, with enterprises and traders' inventories accumulating, while downstream maintains low inventories. Attention should be paid to the restocking rhythm during the peak season [8]. - The propylene market may show a pattern of "both supply and demand increasing", and the price trend is more likely to be range - bound. In August, the weak pattern of the propylene market is difficult to change, and the monthly average price is expected to fluctuate around 6350 yuan/ton [11]. 3.
