透明性が悪くなるという新たな問題点が生ずる。Conventionally, for the purpose of improving the gas barrier properties of plastic films, silicon oxide is deposited on the film surface, as disclosed in Japanese Patent Publication No. 12953/1983. In addition, the silicon oxide vapor-deposited plastic film obtained by semi-continuous winding vapor deposition by the same method has a moisture permeability:
3.0 glm”・24Hrs, below, oxygen permeability:
2. Occ/m"・24Hrs, the following value was obtained, and it is known to be effective. However, moisture permeability: 1.Oglm"-24Hrs,
Below, oxygen permeability: 0.5 cc/m2・2411r
In industrial scale production of silicon oxide vapor-deposited plastic films having the following values, it has been difficult to produce stable products. The reason for this is that a mixture of Si:SiO*=1:l (molar ratio) is used as the evaporation material, and a film of 510 m is formed in the evaporation process. On the other hand, if SiO is used as the evaporation material, generally satisfactory performance can be obtained, but the production cost is high and there are problems in putting it into practical use. In addition, in the case of a single silicon oxide vapor-deposited plastic film, moisture permeability, for example: 2. :1g/s"・24Hrs, Oxygen permeability:
It usually shows a value of 1.8cc/a"・24Hrs, etc. Furthermore, in order to obtain an excellent transparent film with low moisture permeability and low oxygen permeability, the thickness of the silicon oxide vapor deposited film may be increased. Although attempts have been made, the practical problem is that simply increasing the thickness does not improve defects such as minute pinholes and minute cracks, and the resulting film only becomes unsightly colored and has poor transparency. A new problem arises.

つぎに実施例をあげて本発明を説明する。In the present invention, two silicon oxide vapor-deposited plastic films each having a silicon oxide vapor-deposited film provided on one side of the plastic film directly or via an undercoat layer are bonded together so that the side with the silicon oxide vapor-deposited film is on the inside. This is a transparent high-barrier plastic film that is characterized by: That is, in the present invention, two silicon oxide vapor-deposited plastic films each having a silicon oxide vapor-deposited film provided on one side of the plastic film directly or via an undercoat layer are bonded together so that the side with the silicon oxide vapor-deposited film is on the inside. By this, transparency,
Excellent gas barrier properties and retort sterilization resistance, food and drink,
The present invention makes it possible to provide a transparent high-barrier plastic film that can stably be used as a packaging material or gas barrier material in fields such as medical products and electronic materials. As the plastic film in the method for producing a transparent high barrier plastic film of the present invention, any film can be used as long as it has sufficient self-retention properties.
For example, polyethylene terephthalate, polyamide, polyamide, polyethylene, polypropylene, cellulose acetate, polycarbonate, polyvinyl chloride,
A film-like material or a sheet-like material such as a fluororesin is used as appropriate. In particular, as the plastic film, it is preferable to use a film-like material of the above-mentioned resins with a thickness of about 3 to 100 μs because it allows continuous mass production of transparent high-barrier plastic films without wrinkles or cracks. . Further, the plastic film may be -axially stretched or biaxially stretched, and from the viewpoint of gloss 1 strength, etc., biaxially stretched is preferably used. Furthermore, the plastic film may be subjected to surface treatment such as corona discharge treatment or low-temperature plasma treatment, which is generally preferable because it can improve the adhesion between the film and the deposited silicon oxide. Furthermore, the plastic film may have an undercoat layer provided on its surface, and examples of the resin for forming the undercoat layer include thermoplastic resin, 8-curing shelf fat, and electron beam curable resin. , UV-curable resins are used, such as acrylic resins, vinyl chloride-vinyl acetate copolymers, polyvinyl butyral, polycarbonate, nitrocellulose, cellulose acetate, urethane resins, urea resins, melamine resins, and urea. - Preferably used are melamine resins, epoxy thread resins, alkyd resins, aminoalkyd resins, rosin-modified maleic acid resins, etc. alone or in mixtures, and silane coupling agents. To form the undercoat layer, an organic solvent solution, aqueous solution, etc. of the resin for forming the undercoat layer and a coupling agent are applied using a conventional coating method such as a roll coating method, a gravure coating method, a reverse coating method, a spray coating method, etc. This is done by coating the resin by a method and drying (curing in the case of thermosetting resin, electron beam curing resin, ultraviolet curing resin, etc.). The undercoat layer may be colored with a coloring agent such as a general-purpose dye or pigment. A coloring material such as a dye or a pigment is appropriately selected from a range of about 30% of the resin for forming the undercoat layer. The evaporation raw material in the transparent high-barrier plastic film of the present invention is -silicon oxide alone. A mixture consisting of approximately equimolar % of silicon and silicon dioxide, a mixture consisting of approximately equimolar % of silicon and silicon dioxide, and 1 mol% or more and less than 30 mol% of silicon monoxide are used, and the known method is used. It is formed by vapor deposition using a vacuum evaporation method. When 1 to 30 mol% of silicon monoxide is added to a conventional evaporation material containing equimolar amounts of silicon and silicon dioxide, Si+SiO,
42510m...In the reaction system of (1), -silicon oxide plays the role of an initiator to promote the reaction, and the above (1)
) plays a role in ensuring smooth reactions. Therefore, it is a preferred evaporation feedstock in terms of economy and resulting product quality. In the present invention, there is no particular restriction on the thickness of the silicon oxide vapor deposited film, but it may be selected and determined as appropriate depending on the intended use of the product and desired performance. It is usually selected from the range of about 10 to 1000 n-, preferably from about 50 to 200 n. There are no particular limitations on the adhesive and bonding method for the transparent high-barrier plastic film of the present invention, and conventional lamination methods and adhesives may be used. As the adhesion method, for example, an extrusion lamination method, a dry lamination method, a solvent-free lamination method, etc. are used as appropriate. Examples of adhesives include acrylic-vinyl chloride-vinyl acetate,
Adhesion of acrylic, ethylene-vinyl acetate, epoxy, styrene-butadiene, polyester-isocyanate, polyethylene, vinyl chloride-vinyl acetate, vinyl chloride, vinyl acetate, chlorinated polypropylene, urethane, etc. These agents may be used alone or in an appropriate blend. The thickness of the adhesive layer is usually selected from the range of 2 to 100 JJIs, preferably from the range of 3 to ton. If the thickness of the adhesive layer is less than 2 .mu.s, sufficient adhesive strength cannot be obtained, which is undesirable.On the other hand, if the thickness exceeds 100-, no change is observed to the extent that it contributes to the adhesive strength. In addition, the plastic film surface should be protected using the usual method! In addition to an I coating film, a protective film, a heat-sealing layer, etc., a printed layer such as a character design may be provided, thereby expanding its uses. Next, the present invention will be explained with reference to Examples.
