1. A laminate for packaging liquid contents, comprising a substrate layer and a sealant layer, wherein
the sealant layer comprises at least an odor adsorption layer,
the sealant layer 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 comprises a hydrophobic zeolite of which a molar ratio of SiO2/Al2O3 is 30/1 to 10000/1, wherein an increment of TOC concentration of filling water (1000 g, 65° C.) filled in a package of a pouch bag (15 cm×44 cm) produced with the laminate, where an inner surface of the pouch bag was previously subjected to sterilization treatment by UV irradiation (wavelength 253.7 nm for 10 seconds at 25° C.), after storage at 35° C. for 2 weeks is 0.26 ppm or more and 0.70 ppm or less.
