According to the price data from Shengyi Society, on September 19, 2025, the average selling price of PET was 5870 yuan/ton, a decrease of 0.35% from the beginning of the week. The overall price of polyester bottle flakes (PET) is showing a weak downward trend.
Cost support significantly weakened: The international crude oil market fell due to market concerns caused by poor economic data in the United States, while the PTA market remained weak and volatile, making it difficult to effectively support bottle costs.
Supply pressure still exists: domestic polyester bottle production increased by 1100 tons to 330300 tons compared to the previous period, and the capacity utilization rate slightly increased by 0.23% to 72.31%. The ample supply of spot goods in the market continues to suppress the potential for price rebound.
The demand side continues to be weak: downstream terminals (such as the soft drink packaging industry) are mainly focused on rigid procurement, and it is a seasonal off-season with a lack of market momentum and fewer inquiries.
Market sentiment cautious: In the pattern of “weak cost and demand”, the trading atmosphere in the market is generally average, and the mentality is generally cautious.
Business Society predicts that the price of polyester bottle chips is expected to fluctuate weakly within the range of 5750-5900 yuan/ton. Whether the market can stabilize largely depends on whether the cost side (crude oil and PTA prices) can stop falling and rebound, as well as whether downstream demand has substantially improved.
