main gases studied as permeants in packaging applications; they diffuse through the film modifying product quality and shelf-life. Water vapor barrier property of film packaging is important for products whose physical and chemical deteriorations are related to
equilibrium moisture content (Siracusa, 2012). Concerning to oxygen impermeability, it is relevant since this gas promotes a lot of food degradation mechanisms, such as corrosive phenomena, oxidations, and organoleptic properties modifications (Russo, Simon,
& Incarnato, 2006).
