Jiujiang Petrochemical polypropylene packaging bags are thinned to achieve a double harvest of environmental benefits

　　On January 15, it was learned from Sinopec Jiujiang Petrochemical Company that since 2023, Jiujiang Petrochemical has been focusing on market demand, repeatedly investigated, and continued to tackle the problem of thinning and sprinkling of packaging bags, and the thinning of polypropylene packaging bags has successfully achieved a two-level jump, and the thickness of film packaging bags has been reduced from 0.16 mm to 0.14 mm and 0.12 mm.

　　At first, in response to market demand, after thinning the packaging bag, due to the softness of the film bag, the packaging machine grabbed the bag unsteadily and was easy to spill. To this end, the company set up a research team to analyze the reasons, further optimize the parameters of the packaging line, transform the packaging manipulator, and optimize the packaging film formula. After many tests, the stiffness and strength of the film bag do not decrease when the film bag is thinned, which solves the problem of sprinkling materials from the source and reduces packaging waste, which is of great significance to the environmental protection and efficiency of the enterprise.
