Laminate

Abstract: The purpose of the present invention is to provide a laminate which comprises a propylene polymer as a main component, has excellent low-temperature heat sealability and heat seal strength, and has a high peeling energy by controlling a peeling mode. The present invention relates to a sealant film having a heat-fusible layer and an adjacent layer adjacent to the heat-fusible layer, the sealant film being characterized in that the sealant film satisfies the following requirement (1), the heat-fusible layer includes an olefin-based polymer (B) satisfying the following requirement (2) and a propylene-based polymer (A) satisfying the following requirement (3), the adjacent layer comprises 1-70 mass% of the propylene-based polymer (A) satisfying the following requirement (3) and 30-99 mass% of the olefin-based polymer (B) satisfying the following requirement (2), and contains 0-70 mass% of a propylene polymer (B2) in the olefin-based polymer (B) (where, (A) + (B) = 100 mass%). Requirement (1): the sealant film is a stretched film or a non-stretched film. Requirement (2): melting point is less than 120 °C or not observed. Requirement (3): melting point is 121 °C to 170 °C.
