5. Price Prediction

Recently, the processing fees for polyester bottle chips have been continuously squeezed and are at a low level. The market may see a surge in covering short positions, and downstream buyers are also engaging in rigid restocking at low prices, collectively supporting the short-term market bottom price. However, the positive news on the cost side has gradually been absorbed, and the cost support is weakening. In the short term, the market will be primarily driven by cost logic, showing a weak consolidation trend. It is expected that tomorrow, the spot price of polyester bottle-grade chips for water bottles in the East China market will be between 5860-5950 yuan/ton, fluctuating weakly within this range. Subsequent focus should be on changes in raw material prices.
