、特開昭６３−２２３１６３号公報に記載されている。However, since the aluminum oxide vapor deposited film is porous,
Its gas barrier properties were also not sufficient. In order to improve this gas barrier property, a method of subjecting an aluminum oxide vapor-deposited film to a wet heat treatment is described in JP-A-63-222849 and JP-A-63-223163.

ヤ−性が向上する。According to this method, a film on which aluminum oxide is vapor-deposited is stored under high temperature and humidity such as 40°C, 180% R, H0, or immersed in water at room temperature to 40°C to adsorb moisture, and then stored at 40°C to 40°C. Heat treatment to 180°C. The moist heat treatment produces aluminum hydroxide, which seals the pores and improves gas barrier properties.

パラツキが生じるという問題があった。(Problems to be Solved by the Invention) However, such moist heat treatment is performed directly on the aluminum oxide vapor deposited surface. That is, since various treatments are performed while the deposited film is exposed to the outside air, the deposited film is easily damaged or contaminated with impurities, and the film thickness also varies. Therefore, although the gas barrier properties are improved as a whole, there are problems in that the gas barrier properties vary, and the adhesive strength with the vapor deposition substrate also varies.

The plastic film, which may contain a lubricant, a colorant, etc., is preferably a stretched film in terms of strength, elongation, thermal properties, dimensional stability, etc., but may be unstretched.

ツキを生じる結果となる。If the thickness is less than 300 angstroms, the gas barrier properties will not be sufficient. If the thickness exceeds 3000 angstroms, the deposited film becomes hard, the flexibility of the transparent plastic film substrate is impaired, and cracks are likely to occur in the deposited film. The occurrence of cracks results in deterioration and variation in gas barrier properties.

While the lamination strength is extremely excellent, Comparative Example 1
In Examples 1 to 4, the oxygen permeability falls within a width of 0.6cc/rrr-day-arm and the moisture permeability falls within a width of 0.4g/%・day, with extremely small variations. On the other hand, in Comparative Examples 1 and 2, the oxygen permeability was 2.
