Raw materials weaken and demand is weak, the market focus of polyester bottle chips in September shifts downward

On September 28, the price of polyester bottle chips in September 2025 showed a generally weak downward trend. According to the commodity market analysis system, in the first half of September, the price continued to decline, with the average selling price of PET falling to 5840 CNY/ton, a decrease of 0.35% from the beginning of the week. In the last week of September, the price rebounded, and the market price in East China rose to 5900 CNY/ton.

The cost support weakened: the international crude oil market fell due to poor economic data from the United States, causing market concerns, and at the same time, the PTA market was weak and volatile, unable to provide effective support for the cost of bottle chips. As an upstream raw material for polyester bottle chips, the fall in the price of crude oil led to a reduction in the cost of polyester bottle chips, which in turn drove down prices.

Supply-side pressure persists: the production of polyester bottle chips in China increased by 0.11 million tons to 33.03 million tons compared to the previous period, and the capacity utilization rate slightly increased by 0.23% to 72.31%. Although some companies have reduced production, the overall supply remains high, continuously suppressing the space for price recovery.

Demand remains weak: downstream industries such as soft drink packaging mainly rely on rigid demand procurement, and it is currently in the seasonal off-season, leading to a lack of momentum for market volume, and fewer inquiries. End-users mostly adopt a strategy of purchasing as needed, without large-scale procurement activities, which fails to provide upward pressure on prices.

Market sentiment is cautious: under the "dual weakness" of costs and demand, the trading atmosphere in the market is generally lukewarm, and participants are generally cautious. Both buyers and sellers show low enthusiasm for transactions, and the market activity is low, making it difficult for prices to show significant fluctuations, and the overall trend remains weak and downward.

Affected by factors such as weakening cost support, weak demand, and persistent supply pressure, it is believed that the price of polyester bottle chips will maintain a weak fluctuation within the range of 5750-5900 CNY/ton.
