Demand enters the off - season with declining downstream开工率. Inventory is accumulating, and the de - stocking pressure is large. The cost support has increased, but the supply - demand contradiction suppresses the price [3]. - PP: Short - term supply - demand fundamentals have limited changes. Supply is still under pressure, but there may be a slow reduction in supply due to potential production cuts. Demand has limited order follow - up, and only BOPP provides some support. Inventory is high. The cost support has increased, and the short - term price rebound drive is limited [4]. 3.3 Strategy - Single - sided: Cautiously short - sell LLDPE for hedging at high prices; wait and see for PP with short - term weak bottom - side fluctuations [5]. - Inter - period: No strategy [5]. - Inter - variety: Shrink the L05 - PP05 spread when it is high [5].
