According to the price data from SunSirs, on September 19, 2025, the average selling price of PET was 5,870 RMB/ton, a decrease of 0.35% from the beginning of last week. The overall price of PET 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 PET bottle production increased by 1,100 tons to 330,300 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.

SunSirs predicts that the price of PET bottle chips is expected to fluctuate weakly within the range of 5,750-5,900 RMB/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.
