PROBLEM TO BE SOLVED: To provide a laminated film for a liquid packaging bag which accommodates various things such as a liquid food, a condiment, a cleanser, chemicals, permanent lining liquid, motor oil and the like, can be hot-melt bonded efficiently for stable lamination without using an adhesive agent or an AC agent at all, and shows excellent various resistances to the accommodated thing. SOLUTION: The laminated film for the liquid packaging bag is obtained by hot-melt bonding a sealant film 3 of a linear low-density polyethylene polymerized with the laminate face on a base film 2 polymerized using a metallocene-based olefin polymerization catalyst or a sealant film 3 composed of a resin blend containing 10 wt.% or more of the linear low-density polyethylene polymerized using the metallocene-based olefin polymerization catalyst on one surface or both surfaces of the base film 2 of a polyester, nylon or the like.
