Abstract

As a sealant film for laminates that is superior in heat resistance, low-temperature sealability, and impact resistance, there is provided a sealant film for use in a laminate in which the percentage of polypropylene is 80% by mass or more. The sealant film includes at least a first layer positioned at one surface of the laminate and a second layer in contact with the first layer. The first layer contains a first matrix resin component constituting 51% by mass or more and 90% by mass or less and at least one first dispersed component, and has a sea-island structure in which the first dispersed component is dispersed in the first matrix resin component. The second layer contains a second matrix resin component constituting 51% by mass or more and 85% by mass or less and at least one second dispersed component, and has a sea-island structure in which the second dispersed component is dispersed in the second matrix resin component. The first matrix resin component is a propylene-ethylene random copolymer, and the first dispersed component includes 5% by mass or more polyethylene. The second matrix resin component is block polypropylene, and the second dispersed component includes 5% by mass or more polyethylene.
