In the past half month, the price of polyester bottle chips has shown a trend of first suppressing and then stabilizing. In the early stage, it fell due to the drag of costs and demand, and in the later stage, with the increase of production rate and supply, the price fluctuated at a low level.

In early October, the overall performance of the polyester bottle chip market was weak, with prices fluctuating downwards. 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, prices continued to run at a low level. On October 14th, polyester bottle chip factories lowered their quotes by 20-50 yuan. As of October 16th, the market price of polyester bottle chips has increased due to the influence of raw materials. Overall, the price of polyester bottle chips has remained stable after fluctuating and falling in the past half month.
Significant weakening of cost support
The ceasefire agreement reached between Palestine and Israel has eased the geopolitical situation, and international oil prices have fallen. The PTA and ethylene glycol markets, which are direct raw materials for polyester bottle chips, have also shown weakness, causing polyester bottle chips to lose important cost support, which is an important factor in the price decline.
From the perspective of the industrial chain, the absolute price of bottle flakes mainly follows cost fluctuations. Against the backdrop of the collective weakening of upstream raw materials, it is inevitable that the price of bottle chips will fall accordingly.
Supply pressure persists
Although mainstream factories have taken joint production cuts since the middle of the year, and the industry’s capacity utilization rate has remained at 73.37% recently, the market’s spot supply is still sufficient.
In addition, overcapacity is a long-term pressure faced by the industry, which continues to suppress the rebound space of prices.
Weak performance on the demand side
From January to August 2025, the production of soft drinks decreased by 4.8% year-on-year. In October, the weather turned cooler, and the demand for soft drinks and catering declined narrowly. The demand side lacked support for bottle tablets, and downstream end users’ procurement strategies mainly focused on cautious follow-up according to demand, lacking enthusiasm for large-scale stocking, resulting in a shift in the market transaction center.
Overall, Business Society believes that the polyester bottle chip market is expected to continue its weak and volatile pattern in the short term.
