1. A gas-barrier aluminum deposition film comprising:
a thermoplastic base film;
a seed coating layer which is laminated on one surface of the thermoplastic base film and includes 1.0e+5 to 1.0e+10 functional groups of at least one type selected from the group consisting of a hydroxyl group (—OH), an amine group (—NH), and a carboxylic acid group (—COOH) within an area of 300 μm×300 μm; an aluminum deposition layer deposited on the seed coating layer; and wherein the seed coating layer is coated with a copolymer polyester-based coating composition, wherein a water vapor transmission rate (WVTR) of the gas-barrier aluminum deposition film is in a range of 0.01 to 0.5 g/m2·24 hr, and wherein an oxygen transmission rate (OTR) of the gas-barrier aluminum deposition film is in a range of 0.1 to 1.0 cc/m2·24 hr·atm.
