Abstract

To provide a laminate having high impact resistance after retort treatment when used for a packaging bag, such as a retort pouch. A laminate including: a second substrate; a second adhesive layer; and a sealant layer in this order in a thickness direction, wherein the laminate includes only one substrate, the second substrate has a multilayer structure including a first surface resin layer, a polypropylene layer, and a second surface resin layer in this order in a thickness direction and is disposed such that the second surface resin layer faces the second adhesive layer, the second surface resin layer contains a random copolymer of propylene and an α-olefin other than propylene in an amount of 50% by mass or more based on a total amount of the second surface resin layer, the second adhesive layer has a thickness of 1 µm or more and 4.5 µm or less and a modulus of elasticity of 20 MPa or more and 50 MPa or less, and the sealant layer is an unstretched polypropylene film and has a composite modulus of elasticity of 900 MPa or less.
