Zusammenfassung:	PROBLEM TO BE SOLVED: To prepare the subject thin product having specific properties and excellent in heat resistance in sptie of flexibility by applying silicone to a polypropylene-based film. SOLUTION: This film is obtained by applying silicone to at least one face of a polypropylene-based film, controlling tensile modulus of the polypropylene- based film to which silicone is applied to =130 deg.C. The polypropylene-based film is obtained by mixing, e.g. 20-40 pts.wt. polypropylene with 5-20 pts.wt. ethylene-propylene copolymer having >=55wt.% ethylene content and 40-75 pts.wt. ethylene-propylene copolymer having 20 to =40% opacity. Pigment in an amount of >=2 pts.wt. is preferably added to 100 pts.wt. film raw material when the pigment is titanium oxide.
