Sealant film for packaging liquid contents, laminate including same, packaging material for liquid contents, and package for liquid contents

A laminate for packaging liquid contents, which comprises a substrate layer and a sealant layer, wherein

• the sealant layer comprises at least an odor adsorption layer, and has a single-layer or multi-layer structure,
• a resin component of a layer furthest from the substrate in the sealant layer consists of low-elution polyethylene and optionally a high-elution thermoplastic resin, the high-elution thermoplastic resin being at least one selected from the group consisting of polyethylene, polypropylene, methylpentene polymer, and an acid-modified polyolefin resin,
• the odor adsorption layer comprises low-elution polyethylene and an odor adsorbent,
• a concentration of eluting Total Organic Carbon (TOC) contained in a film formed from the low-elution polyethylene is 42 ppm or higher and 99 ppm or lower,
• in a film formed from a single layer of the low-elution polyethylene and having a thickness of 50 μm, the number of pinholes generated after 5000 times of Gelbo Flex at 23° C. is 6.5 or more and 150 or less,
• in the laminate, the number of pinholes generated after 5000 times of Gelbo Flex at 23° C. is 1 or more and 48 or less,
• 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 (wave length 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, and
• the odor adsorbent is an inorganic porous material carrying a chemical adsorbent thereon.
