Abstract
The present invention provides a laminated film having a heat-sealing layer that exhibits adhesion, easy peelability, anti-fogging, blocking resistance, and migration resistance to an A-PET substrate. The laminated film has two layers: a substrate layer and a heat-sealing layer, wherein (i) thickness of the heat-sealing layer is 1 µm or more and 5 µm or less; (ii) the heat-sealing layer comprises a water-soluble polyester resin (A), a water-soluble polyester resin (B), and inorganic particles (C), wherein Tg of (A) is -15°C or higher and less than 20°C, Tg of (B) is 40°C or higher and 70°C or lower, mass ratio of (A) / (B) is 90/10 to 50/50, and a content of (C) in the heat-sealing layer being 0.6 to 10% by mass; (iii) when 1 µL of distilled water is dropped onto the surface of the heat-sealing layer of the laminated film under conditions of 23°C and 50% R.H., water contact angle, as measured 1 second after the dropping is 30° or higher and 60° or lower; (iv) Tg of the heat-sealing layer is 10°C or higher and 25°C or lower; and (v) haze value of the laminated film is 15% or less.
