Abstract:
An object of the present invention is to provide a resin composition for an odor-adsorbing molded article that is excellent in manufacturability, eliminates odor by exerting a high adsorbing effect on odorous organic matter originally contained in packaging materials and odor generated by the decomposition, etc. of resins constituting packages during disinfection/sterilization treatment such as UV irradiation, hot packing, boiling, γ ray irradiation, or EB irradiation, is less likely to desorb the odor once adsorbed and capable of efficiently adsorbing odor and therefore exerts a high adsorbing effect over a long period without reducing the ability to adsorb odor, and is excellent in resistance to change in taste and odor of contents, and an odor-adsorbing molded article prepared from the resin composition for an odor-adsorbing molded article. The present invention provides a resin composition for an odor-adsorbing molded article comprising at least thermoplastic resin A and an odor adsorbent material, wherein the odor adsorbent material comprises hydrophobic zeolite having a SiO2/Al2O3 molar ratio of 30/1 to 8000/1, and a melt flow rate of the thermoplastic resin A is 5 g/min or more and 100 g/min or less, and an odor-adsorbing molded article prepared from the resin composition for an odor-adsorbing molded article.
