Report Industry Investment Rating - Not provided Core Viewpoints - The domestic supply - demand pattern of plastics has improved, and there are still expectations for the chemical industry to counter - involution.

Attention should be paid to the resumption progress of downstream industries after the festival and the development of the Middle East situation [1] Summary by Relevant Catalogs Market Analysis - On March 27, new parking devices such as Qilu Petrochemical's HDPE Line 1 were added, and the plastic operating rate dropped to around 80%, which is at a relatively low level.

After the Spring Festival, the petrochemical inventory has been reduced and is currently at a neutral level in the same period in recent years.

New production capacities of 500,000 tons/year of BASF (Guangdong) FDPE and 300,000 tons/year of Yulong Petrochemical LDPE/EVA were put into operation in January 2026, and there are no plans to put new production capacities into operation in the first quarter. The downstream factories have increased their resumption of work after the Lantern Festival, and the rigid demand has been released intensively, causing the prices of agricultural films in North, East, and South China to continue to rise.
