Concealable film, laminate, and packaging material

A concealable film wherein on at least one surface of a layer A comprising 1 to 40% by mass of an amorphous polyamide resin, 10 to 60% by mass of titanium oxide and 0 to 89% by mass of a crystalline polyamide resin, with a proviso that the total content of these is 100% by mass, the crystalline polyamide resin being one selected from a group consisting of nylon 6 and polymetaxylylene adipamide, the amorphous polyamide resin including terephthalic acid and isophthalic acid as a dicarboxylic acid component and hexamethylenediamine and 4,4′-diamino-3,3′-dimethyl-dicyclohexylene methane as a diamine component, a layer B constituted with a polyamide resin and not including titanium oxide is laminated, the polyamide resin constituting the layer B including 80% or more by mass of nylon 6, the concealable film being stretched and having a thickness of 10 to 30 μm and the concealable film having a multilayer structure that is one of B/A/B and B/A/B/A/B wherein each layer A directly contacts each layer B.
