As the title suggests, 1. Which expert is aware of the main manufacturers of LDPE in China? I can help answer. 2. Additionally, LDPE blown films have a strong odor.

Thank you for the answer. Are there any names of relevant manufacturers? I only know Maoming Petrochemical, Yanshan Petrochemical, etc. Could you provide a few more? It has a strong odor; aside from the role of additives, are there any suggestions for adjustments in the manufacturing process? Regarding the difficulty in untwisting, how should the manufacturing process be adjusted under the same MFI? Please advise?
Qilu, Jinshan, Yangzi, Lanzhou Petrochemical, Jihua, Daqing, Huizhou, Fujian United, Wuhan Sino-Korean Petrochemical, Dushanzi, Sichuan Petrochemical, Tianjin Petrochemical, Zhenhai Refining & Chemical, Panjin, Guangzhou Petrochemical,....... The last two questions are too technical; it’s best to ask a PP/PE process engineer.
