Abstract: The determination of dry tensile properties of a paper wrapping plastic film was performed as well as the percent strain at break, the elongation in mm, in both directions, the machine direction, and the counter machine direction. We observed a correlation between stress and tensile strain in % by linear function. Also, the thickness of the plastic film was measured and was found to be 0.16mm. The dry tensile strength in the machine direction increased linearly with decreasing film thickness. The tensile strain at break in % increased linearly with increasing film thickness in the machine direction. The dry tensile strength across the cross-machine direction increased linearly with increasing film thickness. Also, the geometrical mean of the tearing resistance in mN was calculated and was correlated linearly with film thickness. The elongation at break in % in both directions increased as the film thickness increased. Finally, the plastic film was considered isotropic.
