(57) [Abstract] (Correction) [Problem] A laminated film and a packaging bag which are excellent in strength, moisture resistance, transparency and the like and are suitable as a packaging material for protecting electronic parts from moisture and static electricity. SOLUTION: This is a laminated film, wherein (1) the outermost layer is a stretched nylon film (A) or a vapor deposition film (B). And (2) the innermost layer is the heat seal layer (D), (3) The vapor-deposited film (B) is a transparent inorganic vapor-deposited film b on at least one surface of the transparent polymer film substrate b1. 2 is formed, and (4) the gas barrier layer (C) is provided on at least one surface of the transparent polymer film substrate c1 via the transparent inorganic vapor-deposited film c2 and polycarboxylic acid or its partial neutralization. A gas barrier layer comprising at least one composite vapor deposition film (C 1 ) having a water resistant film c3 formed by heat treating a coating film of a mixture containing a substance and a saccharide. |
