は満足するものが得られなかった。In Comparative Example 2, only Al vapor was used.
In addition, since the OD was low, the water vapor barrier property was poor, and the metallic luster was slightly inferior.

劣ったものとなった。In Comparative Example 3, since the OD was as high as 4.3, the vapor-deposited film was discolored and unevenly deformed due to heat loss, and the vapor-deposited surface was inferior in beauty. Probably because of pinholes due to blocking at the time, the water vapor barrier property was also inferior, and the vapor deposition film adhesion was also inferior.

る。The vapor-deposited film of the present invention having the above-mentioned constitution has the following effects. (1) Since vapor-deposited aluminum and metals with atomic numbers 12 to 30 and non-metals, the vapor-deposited film is beautiful and has excellent water vapor barrier properties. (2) Since the vapor-deposited film has an optical density (OD) of 1.0 to 3.0, the vapor-deposited film has a beautiful vapor-deposited surface with no omission due to blocking or the like, and has an excellent water vapor barrier property. (3) Water vapor transmission rate 0.025 (g / 100cm 2 · 2
It is easy to obtain a vapor-deposited film of 4 hr / 18 μ) or less, which is suitable as a packaging material for snack foods and baked confectionery.
