聚烯烃日报：传统旺季将来临，关注需求端启动-20250829

Report Industry Investment Rating - Unilateral: Neutral; Inter - period: None; Cross - variety: None [3] Core Viewpoints - The traditional consumption peak seasons "Golden September and Silver October" are approaching. The demand for PE downstream agricultural films and greenhouse films is gradually starting, and the packaging film industry is stocking up in advance. The plastic products industry is recovering with the seasonal demand growth of home appliances and automobiles. The number of PE parking and maintenance devices has increased, slightly alleviating the supply pressure. However, the overall current operation is still at a relatively high level, with production enterprises accumulating inventory and upstream facing certain de - stocking pressure. The PP operation rate is flat month - on - month, and the inventory in the upstream and mid - stream links has decreased slightly. New PP production capacity is continuously being released. The international oil price shows a weak trend, the oil - based production profit is acceptable, the propane price has increased slightly, and the PDH - based PP profit is near the break - even point [2] Summary by Directory 1. Polyolefin Basis Structure - It includes the trend of plastic futures' main contracts and the basis between LL East China and the main contract, as well as the trend of polypropylene futures' main contracts and the basis between PP East China and the main contract [8][11] 2. Production Profit and Operation Rate - For PE, it involves LL production profit (crude oil - based), PE operation rate, PE weekly output, and PE maintenance loss. For PP, it includes PP production profit (crude oil - based), PP production profit (PDH - based), PP operation rate, PP weekly output, PP maintenance loss, and PDH - based PP capacity utilization [19][22][29] 3. Polyolefin Non - Standard Price Difference - It covers the price differences between HD injection molding - LL East China, HD blow molding - LL East China, HD film - LL East China, LD East China - LL, PP low - melt copolymer - drawn wire East China, and PP homopolymer injection molding - drawn wire East China [28][35][36] 4. Polyolefin Import and Export Profit - For LL, it includes LL import profit, the price difference between LL US Gulf FOB and China CFR, the price difference between LL Southeast Asia CFR and China CFR, and the price difference between LL Europe FD and China CFR. For PP, it involves PP import profit, PP export profit (to Southeast Asia), and the price differences between PP homopolymer injection molding from different regions and China CFR [43][53][61] 5. Polyolefin Downstream Operation and Downstream Profit - It includes the operation rates of PE downstream agricultural films, packaging films, and winding films, as well as the operation rates and production profits of PP downstream plastic weaving, BOPP, and injection molding [62][63][71] 6. Polyolefin Inventory - It includes the inventories of PE oil - based enterprises, PE coal - chemical enterprises, PE traders, PE ports, PP oil - based enterprises, PP coal - chemical enterprises, PP traders, and PP ports [73][78][83]
