Zusammenfassung:The purpose of the present invention is to provide a laminate which contains a propylene polymer as the main component, has excellent low-temperature heat sealability and heat sealing strength, has a controlled peeling pattern, and has high peeling performance, and is characterized by having a heat-fusion layer and an adjacent layer adjacent to the heat-fusion layer, the sealing film satisfies the following requirement (1), the thermal fusion layer contains an olefin polymer (B) satisfying the following requirement (2) and a propylene polymer (A) satisfying the following requirement (3), and the adjacent layer is formed from 1-70 mass% of the propylene polymer (A) satisfying the following requirement (3) and 30-99 mass% of the olefin polymer (B) satisfying the following requirement (2). The olefin polymer (B) contains 0-70 mass% of a propylene polymer (B2) (wherein (A) + (B) = 100 mass%). ). Requirement (1): the sealing film is a stretched film or an unstretched film. Requirement (2): the melting point is low
