PROBLEM TO BE SOLVED: To provide an easily separable laminate film which has excellent properties, i.e., has excellent water resistance as a substrate for concealing seals, replacement preventive labels, etc., and does not require any special processing for starting the separation. SOLUTION: This easily separable laminate film comprises a base layer (A) formed of a thermoplastic resin, a delamination layer (B), and a surface layer (C) stacked on top of one another in that order. In the easily separable laminate film, the peel strength of the delamination layer (B) is 5 to 150 g/cm- width, and the breaking strength of the surface layer (C) is not more than 500 g/cm-width. In another construction of the easily separable laminate film, the delamination layer (B) contains 10 to 80 wt.% inorganic. fine powder and/or organic filler and 90 to 20 wt.% thermoplastic resin. In a further construction of the easily separable laminate film, the thickness of the base layer (A) is 10 to 500μm, the thickness of the delamination layer (B) is 0.1 to 10μm, and the thickness of the surface layer (C) is less than 10μm.
