Report Industry Investment Rating - Not provided Core Viewpoints - On January 28, the plastic operating rate remained at around 89%, at a neutral level. As of the week of January 23, the downstream operating rate of PE decreased by 1.4 percentage points to 39.53%, still at a relatively low level in the same lunar period in recent years. Near the end of the month, petrochemical inventory reduction was fast, and the current petrochemical inventory was at a relatively low level in the same period in recent years. Driven by low valuation, cold weather and the geopolitical situation in Iran, the sentiment of the chemical sector improved, and plastics followed the market sentiment to fluctuate strongly in the short term. However, the improvement of the plastics supply - demand pattern was limited, the spot follow - up was limited, the basis weakened, and the sustainability of the plastics rebound should be treated with caution. Due to the new production capacity of plastics put into operation recently, the operating rate was higher than that of PP, and the concentrated demand for mulch film had not started yet, so the L - PP spread was expected to decline [1].
