Abstract: A polyester multi-layer film of the present invention comprises: a substrate layer comprising polyester; and a skin layer located on at least one surface of the substrate layer, wherein the polyester multi-layer film suppresses generation of oligomers in the film and migration to the surface even in a high-temperature treatment process by satisfying a predetermined correlation between the concentration of cyclic oligomers in the film and a haze value before and after heat treatment, thereby maintaining transparency and visibility of the film in the long term.

Abstract: In a gas-barrier aluminum deposition film according to one embodiment of the present invention, a seed coating layer containing functional groups of at least one type selected from among a hydroxyl group (—OH), an amine group (—NH), and a carboxylic acid group (—COOH) is formed on a thermoplastic plastic base film to form a seed molecular layer that enables uniform deposition of aluminum, such as AlOx or AlNx, through chemical reaction, on a surface of the coating layer, with aluminum atoms vaporized at the initial stage of aluminum deposition, thereby inducing uniform deposition of an aluminum layer to be subsequently deposited. Therefore, it is possible to provide a deposited film having superior oxygen and water vapor barrier properties compared to existing aluminum deposition films.
