  • Patent number: 11851551
    Abstract: The present invention provides: a sealant film for packaging liquid contents, which is excellent in manufacture suitability, exhibits the effect of being highly adsorptive against an eluting organic substance that a packaging material inherently contains, and odors generated by decomposition of a package-constituting resin and the like, at the time of sterilization/disinfection treatment, and is excellent in resistance to an odor-taste change for the liquid contents; and a package for liquid contents, produced using the sealant film. A sealant film for packaging liquid contents includes at least an odor adsorption layer, wherein the sealant film is formed from a resin composition containing low-elution polyethylene, the odor adsorption layer is formed from a resin composition containing the low-elution polyethylene and an odor adsorbent, a concentration of eluting TOC contained in a film formed from the low-elution polyethylene is 1.

  • Patent number: 11597824
    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, ? 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.
