A sealant for polypropylene consisting essentially of a composition comprising a high-pressure-processed low-density polyethylene (A) having a density of 910 to 930 kg/m3 and an MFR of 0.5 to 20 g/10 min; and an ethylene/alpha-olefin copolymer (B) having a density of 860 to less than 890 kg/m3, an MFR of 0.5 to 40 g/10 min and an Mw/Mn of 1.5 to 3, and/or a linear low-density polyethylene (C) having a density of 890 to 940 kg/m3 and an MFR of 0.2 to 30 g/10 min. In this composition, the component (A) is contained in an amount of 10 to 85% by weight, the component (B) in an amount of 50% by weight or less, and the component (B) and component (C) in a total amount of 15 to 90% by weight, based on the total weight of components (A), (B) and (C).
