Multilayer packaging films are becoming increasingly complex due to the expanding number of layers, types of polymers and blend components that a typical structure contains. Designing or modifying today’s multilayer films usually requires expensive, time-consuming trials on commercial or pilot film lines. A mathematical model that accurately predicts critical performance properties from component materials and basic principles could potentially reduce trial costs and accelerate structure development. Developing such a model however, is very challenging due to the broad range of possible structures and conditions and the fact that many film properties are non-additive and/or non-linear.
