A simplified approach to predict the mass transport properties of micro-perforated films was presented. It was based on a second-degree polynomial function. To the aim, different films with and without various micro-perforations were tested for gas and water vapor permeability, under proper conditions. Surface response plot of interactions between hole diameter and number of holes per area, relative to gas and vapor permeability were determined. The mean relative deviation modulus between experimental and predicted data assessed the model.
