To provide a laminated film capable of being subjected to stable lamination processing not causing separation failure at the time of transfer and peeling such as "a problem of non-separation", "a problem of the interlayer separation of a transfer layer" or the like caused by high speed processing due to high temperature heating when a base material is peeled using the "stiffness" of the paper sheets of printed matter after lamination.
In the laminated film wherein a protective film layer is provided on a heat-resistant base material in a peelable manner, the peel strength F of the protective film layer from the heat-resistant base material is set to 1-50 N/m when heat treatment at 200°C is applied to the laminated film from the surface opposite to the protective film layer of the heat-resistant base material.
