This week (September 8th to September 12th, 2025), the overall price of polyester bottle chips showed a weak downward trend. As the mainstream market, the average price of polyester bottle flakes in East China was 5885 yuan/ton on September 12th, a decrease of 10 yuan/ton from the beginning of the week. The quotation range for goods from September to November is between 5800-5980 yuan/ton, and the delivery range is between 5790-5830 yuan/ton, with relatively few market inquiries.
Insufficient cost support: This is the main pressure for the weakening of prices this week. The international crude oil market fell due to concerns about OPEC+launching new production plans. At the same time, although the operating load of PTA, the main raw material, is not high (69.11%), the spot market is sufficient, and its market is weak and volatile, making it difficult to effectively support the cost of bottle chips.
The supply side has contracted slightly, but inventory pressure still exists: mainstream producers maintain their production reduction strategy, and the weekly operating rate of the industry remains at 70.9%. However, with sufficient spot supply in the market and a relatively high inventory availability of 16.97 days in the polyester bottle chip factory, high inventory continues to suppress the room for price rebound.
Weak demand side: Downstream terminals (such as the soft drink packaging industry) are mainly focused on rigid procurement, and the sustainability of centralized replenishment is limited, resulting in a lack of market momentum for increasing volume. End users often adopt a strategy of on-demand procurement, resulting in fewer market inquiries.
Business Society believes that in the short term, under the pattern of “weak cost and demand”, the market mentality is generally cautious and the trading atmosphere is average. The price of PET spot market is expected to fluctuate weakly within the range of 5800-5950 yuan/ton in the short term, mainly due to narrow fluctuations on the cost side. The actual trend still needs to pay attention to changes in external news, equipment changes, and demand recovery.
