Abstract. Polymeric films play a vital role in food packaging, offering protective barriers that preserve the quality, safety, and shelf life of food products. Their performance depends on properties such as mechanical strength, thermal stability and permeability. Permeability is particularly important as it regulates the transfer of gases from the environment to food. Thus, permeability affects the shelf life, taste and safety of food products. The interaction between nanoscale surface features and permeability is a critical but under-explored aspect of film design. This study aims to test capability of surface topographical characterization as an alternative quality inspection tool for permeability in commercial polymer films. Advanced techniques such as Atomic Force Microscopy (AFM) are used to characterize surface features including roughness and morphology. The results will provide an alternative route for the permeability quality control in manufacturing processes of state-of-the-art commercial polymer films for food packaging.
