According to reports, the project adopts the leading technology of asynchronous biaxial stretching with a width of 6.6 meters in China, and builds two asynchronous biaxial stretching nylon production lines with a single-line production capacity of 12,000 tons/year. The total investment is 397 million yuan and the total construction area is 18670.49 square meters. Rice, which will be completed and put into operation in 2023 and 2024, respectively, when Tianjin Changlu Haijing biaxially oriented nylon film will have one-tenth of the domestic market share, which will play a supporting role in promoting the development of the domestic nylon industry.

Biaxially oriented nylon film is a new type of high-grade packaging material. Compared with traditional polyvinyl chloride film and polyester film, it has good high and low temperature resistance, rupture resistance, impact resistance, puncture resistance and odor barrier properties. It is used for packaging materials in food processing, medical and health, chemical products and other industries, especially suitable for frozen packaging, vacuum packaging and retort packaging, and has a good effect on food preservation and aroma preservation.
