い。2. Description of the Related Art Packaging materials are required to prevent gas permeation in order to protect and preserve their contents, and various attempts have been made so far. For example, attempts have been made to provide an inorganic coating layer such as silicon oxide or aluminum oxide, laminate a gas barrier resin layer such as polyvinylidene chloride, or laminate a metal film of aluminum foil. In addition to this, JP-A-3-183
No. 759 discloses that a plastic film is coated with the same synthetic resin as the plastics in a thin film form by vacuum deposition or sputtering to form an organic material layer, and an inorganic material is deposited thereon to form a mixed layer of the organic material and the inorganic material. A laminated film formed and having an inorganic layer formed thereon is shown. Since this plastic is a substance that is completely different from the inorganic substance of the coating layer and has a poor affinity, the plastic is coated with the same synthetic resin, and in order to improve the fixing property of the inorganic coating, the synthetic resin and the inorganic substance are in the middle. Although the blend layer is formed, since the surface of the blend layer has not only the surface of the inorganic material but also the surface of the synthetic resin, the fixing property of the inorganic material layer is not improved as expected. In addition, 2 synthetic resin and inorganic
The vapor deposition in the process cannot be applied to, for example, a molded body other than the sheet-shaped material. Further, when the synthetic resin is vapor-deposited, the molecular weight is lowered, so that the workability of the plastics material is deteriorated.
Because of this problem, it is not completely satisfactory.

Even in the above example, the plastics material provided with the inorganic coating layer has a small barrier property and cannot sufficiently prevent the deterioration of the contents. Further, when polyvinylidene chloride is laminated, the gas barrier property is good, but when the packaging material is discarded, chlorine is sometimes generated, which is a problem. When aluminum foil is laminated, it becomes opaque and the contents become invisible, and since microwaves are blocked, it cannot be heated by a microwave oven. The present invention has solved all of these problems.

乗効果によってガス遮断性が著しく向上する。The first feature of the present invention is that a polymer coating layer of an organic silicon compound containing silicon, carbon and oxygen is provided on a plastic material. This layer is not itself gas barrier. The second feature of the present invention is that a silicon oxide layer is provided on the first layer. Even if the silicon oxide layer is directly provided on the plastics material as described above, it does not have a sufficient effect of blocking gas permeation. However, when the second layer is provided on the first layer, the synergistic effect of the two significantly improves the gas barrier property.

となるからであると考えている。The reason why such special effects are exhibited when these two layers are laminated in this order is not necessarily scientifically elucidated, but the present invention has the effect of repetitive reproduction. The inventor believes that the gas barrier effect of the silicon oxide layer is largely due to the stable fixing property of the silicon oxide fine particles supplied onto the coated substrate. That is, the supplied particles move on the plastic substrate and are stabilized and fixed at the most stable place. In this case, when a polymer film of a silicon compound containing silicon, carbon and oxygen is formed on the plastic substrate, the silicon oxide fine particles are well stabilized and fixed. It is considered that the distribution becomes uniform, and the particles are stabilized and the oxide fine particles are further stacked on the silicon oxide particles to form a silicon oxide coating, resulting in a tight coating.

If the thickness of the coating layer is thicker than this, the gas barrier property deteriorates.

用に使用することが出来る。The second layer is a layer made of silicon oxide, and this layer is a metal compound other than silicon oxide, such as Mg.
It may also contain O, MgF2, CuCO3, or the like. However, this second layer is mainly composed of silicon oxide, which should preferably be present in an amount of 60% or more, more preferably 65% or more. The silicon oxide coating of the second layer can be formed by the PVD method using silicon oxide such as silicon dioxide and other metal compounds. The third feature of the present invention is that the plastics material provided with such a gas blocking layer has no problem in disposal and can be recycled. Examples of the plastics material for disposing the gas barrier layer of the present invention include polyester resins such as polyethylene terephthalate, polyolefin resins such as polyethylene and polypropylene, nylon, polyvinyl alcohol,
Examples thereof include polyvinyl chloride resin and polycarbonate resin.
Since the plastics material provided with the gas barrier layer of the present invention does not have good moldability, it is preferable to cover the molded container such as a bottle, bag or box with the gas barrier property. The plastic film provided with the gas barrier layer can be processed into a bag by laminating a protective layer on the gas barrier layer. Since the gas barrier plastics of the present invention have good fixability of the gas barrier layer, they withstand hot water sterilization and can be used for retorts.
