FILM FOR INDIVIDUAL PACKAGING BODY OF SANITARY NAPKIN

摘要

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 <=25kgf/mm<2> in both directions of length and width and controlling the melting temperature measured by DSC 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 <=40wt.% content and molding these components. The thickness of the film is preferably 15-50μm. Pigment such as titanium oxide is preferably added thereto so as to have >=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.
