Abstract

A laminate includes at least a substrate layer and a sealant layer. A seal surface of the sealant layer after the laminate is subjected to moist heat treatment has a surface softening temperature of 140°C or higher and 150°C or lower, as measured by local thermal analysis, and the substrate layer and the sealant layer contain a polypropylene-based resin. In the laminate, the seal surface of the sealant layer may have a surface softening temperature of 110°C or higher and 140°C or lower, as measured by local thermal analysis, and the sealant layer may have a fusion strength of 2.0 N/15 mm or lower when heat-sealed to an identical sealant layer under conditions of 121°C, 0.05 MPa, and 30 seconds.
