price trend
In early October, the overall performance of the polyester bottle chip market was weak, and prices fluctuated downward. According to data from Shengyi Society, on October 10th, the market price in East China closed at 5812 yuan/ton, a decrease of about 40 yuan/ton compared to before the holiday. Subsequently, most polyester bottle chip companies lowered their prices by 20-50 yuan/ton.
Mid low stable: On October 14th, polyester bottle chip factories lowered their prices by 20-50 yuan, and on October 16th, some brands’ prices rose by 30 yuan due to the impact of raw materials. Overall, prices remained stable after fluctuating and falling in the middle of the month.
In the second half of the year, it first fell and then rose: According to data from Shengyi Society, on October 24th, the average selling price of PET was 5755 yuan/ton. At the beginning of the week, the price of polyester bottle chips fell due to the weakening of crude oil. Subsequently, geopolitical risks drove oil prices to rebound, cost support rebounded, and prices stopped falling and rebounded. On October 29th, the market experienced a slight correction, and on October 30th, the market rose narrowly again.
market analysis
Cost factor: In early October, international oil prices fell due to the easing of geopolitical tensions such as the ceasefire between Palestine and Israel, and the PTA market also showed weakness, resulting in the loss of important cost support for bottled tablets, which is the main pressure for price decline. In mid to late October, geopolitical risks once again pushed up oil prices, coupled with favorable policy releases: the Raw Materials Industry Department of the Ministry of Industry and Information Technology announced that it will hold a symposium on the development of the PTA and bottle grade polyester chip industry on October 29th. This move aims to prevent and resolve industry competition, greatly boosting market confidence and becoming an important force in promoting cost expectations and bottle chip price rebound
Supply and demand relationship: In terms of supply, the industry’s capacity utilization rate remained around 72.59% this week, and mainstream factories continued to implement production reduction plans. However, the market’s spot supply is still abundant, and overcapacity is a long-term pressure faced by the industry, which has suppressed price increases. In terms of demand, currently in the off-season of seasonal demand, the cooling weather has led to a narrow decline in demand for soft drinks and catering. Downstream end users mostly adopt the strategy of “on-demand procurement” and lack enthusiasm for large-scale stocking.
Export situation: According to customs statistics, the total export volume of polyester bottle flakes from January to September 2025 reached 4.81 million tons, a year-on-year increase of 14%. Among them, the export volume in September was 468000 tons, a year-on-year increase of 7% but a month on month decrease of 10%. Affected by upstream raw materials, the export quotation of polyester bottle chip factories has been raised, and the negotiation range for mainstream bottle chip factories in East China has been extended to $750-770/ton FOB Shanghai Port.
Business Society believes that the future market will be warm and volatile. The cost side is expected to strengthen under the support of geographical factors, which will provide cost support for bottle flakes. However, due to stable supply and abundant spot goods, as well as seasonal off-season demand, the upward space for bottle flake prices is limited, and it is expected to fluctuate within the range of 5600-5800 yuan/ton.
