In a general sense, the structure of a multilayer coextruded film depends on the functional requirements of the film. On the premise of meeting process requirements, through the combination of different polymers, the functional requirements of packaging materials such as barrier, heat seal, body strength, thermal puncture, environmental resistance, secondary processing characteristics, extended storage and shelf life, etc. From the analysis of functional requirements, a combination of five polymers is sufficient. However, co-extruded composite films with seven, nine, eleven, or even more layers have begun to be used in the market, making it a trend and rapidly developing. The structural design of co-extruded films is gradually required to systematically achieve the ideal state of integrating functions, technology, cost, environmental protection, safety, and secondary processing.
