Abstract: Multilayer films consisting of a core layer of nylon 6 sandwiched between two linear low density polyethylene films were produced using a semi-industrial cast film extrusion line. The core layer of the films was produced from non-nylon and nylon / clay nanocomposite resins. The films were consequently uniaxially stretched in machine direction. The effect of stretching on crystalline structure as well as mechanical and permeability properties of the samples was investigated. The orientations of the films for both layers: polyethylene and nylon were evaluated by FTIR (Fourier Transform Infrared Spectroscopy) and it was found that clay inclusion hindered the orientation of the core nylon layer. The interaction of nylon molecules with clay influences the crystalline transformation of the nylon / clay nanocomposite film during the stretching.
