PURPOSE:To provide the title compsn. excellent in deodorizing properties, adsorptivity, germicidal action, purifying properties, etc., by dispersing porous fine particles of dellenite in a crystalline high-molecular material and molding the mixture into a film. CONSTITUTION:Dellenite which is a kind of a rock belonging to rhyolite and composed of about 70% silicon dioxide, about 15% aluminum oxide MgO, K2O, Na2O, CaO, FeO, Fe2O3, TiO, anhydrous titanium oxide, phosphoric anhydride, MnO and adherent moisture is crushed and then ground for 1-24hr to obtain porous fine particles (B) having a diameter of 0.1-100mu, pref. 0.1-20mu. 0.1-5wt.% component B is dispersed in a crystalline high-molecular material (A) (e.g., PE) which is a carrier. The mixture is molten, oriented 1.5-5 times as long and molded into a film or a sheet.
