Abstract

The invention provides a laminated film. The laminated film includes a polyester substrate film, and a coating layer on/over at least one surface of the substrate film. The coating layer includes a resin composition including a resin having an oxazoline group. The laminated film has an inorganic thin-film layer on/over the coating layer, and a protective layer that has a urethane resin and has an adhesion amount of 0.15 to 0.60 g/mon/over the inorganic thin-film layer. The laminated film shows a total reflection infrared absorption spectrum having a ratio P1/P2 ranging from 1.5 to 3.5 wherein P1 is the intensity of a peak having an absorption maximum in a range of 1530±10 cm, and P2 is that in a range of 1410±10 cm. The laminated film further has an oxygen permeability of 5 ml/m·d·MPa or less under conditions of 23° C.×65% RH.
