The achievement will be transformed by self investment and will be successfully transformed in 2021. The result improves the toughness of the end face of the film roll, prevents the end face damage caused by collision, and has good fall resistance. At the same time, the breaking tensile rate of the winding film is improved, and the protection of the packaging product is greatly improved in actual use.

At present, this achievement has been successfully transformed into our high-tech product - polyethylene blown film for packaging, which has brought considerable economic benefits to our company.
