Later, driven by the unexpected maintenance of polyester raw material units and the resulting cost increase, factory offers rose by 20-50 yuan. However, the willingness of buyers to follow up on the price increase was insufficient, leading to a decline in transactions by the end of the day. Offers for goods delivered from August to October ranged from 5,930 to 6,120 yuan/ton, with counteroffers between 5,890 and 6,030 yuan/ton.

5. Price Forecast

The current market is characterized by the core contradiction of "cost support" and "weak demand": the supply side remains stable, with previously tight factory supplies gradually easing, weakening supply-side support. Downstream demand continues to be weak during the peak season, with "weak chasing of price rises" becoming the norm. Purchases are only made on a just-in-time basis when prices are low, and the trading atmosphere is subdued, making it difficult to push prices upward. In the short term, although the market is dominated by cost logic, the overall range is weak under the influence of weak supply and demand. 。 The spot price of polyester bottle-grade chips in the East China market is expected to be 5880-5950 RMB/ton tomorrow, slightly lower at 5870-5890 RMB/ton, and slightly higher at 6030-6400 RMB/ton, with weak fluctuations in the range. Future attention should focus on changes in raw materials.
