The daily production proportion of raffia increased by 2.97% compared to last week, reaching 30.94%. This is mainly due to Beihai Refining's 200,000 tons per year, Gulei Petrochemical's 350,000 tons per year, and Jineng Chemical's 900,000 tons per year units switching to raffia production, with an expected increase in raffia output of 4,350 tons per day.

③、（20250919-0925） The supply-demand balance in this period remains tightly balanced. ， The supply-demand gap has narrowed somewhat, continuing to support market sentiment. The supply-demand balance gap for the next period is expected to narrow due to increased supply, which is anticipated to weaken the support for prices.

2. Spot Overview

As a benchmark for the East China region, today's polypropylene filament closed at 6,762 yuan/ton, down 2 yuan/ton from yesterday. The national average price of filament decreased by 2 yuan/ton from yesterday, down 0.03% from last week, in line with the morning forecast.

Futures opened lower and fluctuated today. In the morning, market quotations remained stable with some areas seeing a decrease of 10-20 yuan/ton.

The supply and demand fundamentals are in a state of stalemate and contention. The market is expected to experience narrow fluctuations in the near term. As of midday, the mainstream price for East China raffia is between 6,750-6,850 yuan/ton.

5. Market Sentiment

With the National Day holiday approaching, downstream buyers are mostly purchasing on demand, while upstream producers are pre-selling resources in advance to mitigate the risk of holiday inventory. Intermediaries are mainly maintaining low inventory to promote transactions.

6. Price Forecast

The National Day holiday impacts have accelerated the pre-holiday destocking process in the industry chain. Due to the prominent long-term oversupply contradiction in polypropylene, upstream production enterprises are conducting maintenance and reducing load to avoid market risks. On the demand side, there is weak pre-holiday restocking intention, with post-holiday on-demand procurement mode, leading to a weak and fluctuating market situation. Recently, there are limited variables on the supply and demand side, and it is expected that the short-term market will weakly fluctuate around 6750-6850 yuan/ton.
