3M Barrier Films are designed to provide a barrier to water and oxygen transmission while maintaining the optical transmittance characteristics of the base films. These films are used in both display and flexible electronic applications where water and oxygen sensitivities are present. In the area of flexible photovoltaics most of the emerging technologies like CIGS, OPV and perovskites require ultra barrier films to protect them from degradation in the field.
3M has the unique capability to make roll to roll barrier films in wide format allowing for large scale barrier film volume. We will provide an introduction to ultra moisture barrier film construction and performance as well as highlight the features and characteristics of the barrier film products that are currently commercialized.
