-
First generation technology
The "blown film method" is adopted, which belongs to the earliest synchronous film method.
-
Second generation technology
By adopting the " 1. Sequential biaxial stretching method", the performance of film has been significantly improved, and the industrialized production level of film has been greatly improved.
-
Third generation technology
The "mechanical simultaneous stretching technology " has a good balance, and the application limitations caused by the arch effect can be solved.
-
Fourth generation technology
The " 3. The state-of-the-art LISIM simultaneous stretching technology " is adopted to control the stretching ratio more flexibly to obtain functional film products with stronger comprehensive performance. It can meet the customized and personalized market demand
-
Fifth generation technology
Adopting "low-carbon biaxial stretching technology", on the one hand, it breaks through the limits of width and speed, On the other hand, through multi-dimensional innovation such as formula research, film structure design and process technology, reduce carbon emissions in the process of production and reduce the carbon footprint of products.
