摘要：

PROBLEM TO BE SOLVED: To provide a laminated sheet, a molded product, a lid, a container, and a package which have excellent sealability.SOLUTION: A laminated sheet 1 has at least a base material layer 2 and an easy-seal layer 3. The thickness of the base material layer 2 is 90 to 1990 μm inclusive. The thickness of the easy-seal layer 3 is 10 to 1000 μm inclusive. The base material layer 2 contains a propylene homopolymer or a propylene random copolymer having an isotactic pentad fraction of 85 to 99% inclusive, a melt flow rate (MFR) of 0.5 to 10 g/10 min inclusive, and a melting point of 150°C or higher. The easy-seal layer 3 contains a propylene random copolymer which is polymerized using a metallocene catalyst and has a melting point of 100 to 120°C inclusive.
