PROBLEM TO BE SOLVED: To improve adhesion and resistance to blocking of printed material by providing, on at least one film surface, a specified amount of a primer layer composed of resin and a surface-active agent. SOLUTION: On at least one surface of a biaxially oriented polyamide film composed of a linear high-molecular compound having amide bond in a molecule such as polycaprolactam, a polyamide film is applied so that a primer layer is 0.01-0.03 g/m<2> after orientation of the polyamide film. The primer layer may be a solvent type, however a layer composed of a nonionic surface active agent composed of water-dispersed polyurethane resin, and polyethylene glycol alkyl alcohol ether, etc., used, for easy controlling of the crosslinking degree of polyurethane resin, and in consideration of environmental problems in a manufacturing site. |
