Abstract: A thermoplastic film is provided that includes a biaxially-oriented polyethylene terephthalate (PET) layer, a tensile strength in the longitudinal and transverse directions of about 2000 kg/cm2 or 3000 kg/cm2 or more, and a tear force in the longitudinal direction that is about 1.5 times as large as a tear force in the transverse direction. Such a film can include two or more layers. Processes for producing the thermoplastic film are also provided.
