Recently, the plastic film is used as wrapping and industrial materials in a wide field. Especially the demand of a contractility heating plastic film increases because this film can adjust to wrapping the varied merchandise. In this research, the deformation of the plastic film was simulated when the plastic film is stretched by the internal pressure and tension in both machine direction and transverse direction of the film. Then, it reports on the result of doing a basic examination by finite element method (FEM) considering tensile characteristic in which temperature dependency.
