摘要: 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 1.5 ppm or higher and 250 ppm or lower, and the odor adsorbent is an inorganic porous material carrying a chemical adsorbent thereon; and a packaging material for liquid contents and a package for liquid contents are produced using the sealant film.
