1. Report Industry Investment Rating - No relevant content provided. 2. Core Views of the Report - The polyolefin price trend was divided this week. The continuous decline in the PE agricultural film operating rate led the L main contract to seek the bottom unilaterally. The PP operating rate was decent, and the slight increase in the BOPP operating rate supported the PP main contract price. Overall, the fundamental situation remained one of strong supply and weak demand, and there was significant upward pressure on polyolefins as a whole. It is expected that the PE main contract will fluctuate weakly, with attention on the 6300 support level. The PP main contract will fluctuate within a range, with attention on the 6200 support level. The LP spread is expected to narrow [9]. 3.
