2. Description of the Related Art Conventionally, plastic films, metal foils,
One or more kinds of cellophane, etc. are laminated to produce a laminated material, and then the laminated material is used to make a bag into a bag-shaped container body, and then the bag-shaped container is produced. A container semi-finished product is manufactured by filling and packaging desired foods and drinks in the container body, and then the semi-finished packaging product is heated at 110 ° C to 130 ° C for 3 hours.
Heat-pressure sterilization treatment is performed for about 0 to 50 minutes to produce retort-processed packaged foods in various forms. Thus, as the laminated material constituting the bag-shaped container body,
Specifically, for example, as a laminated material for producing a transparent pouch for retort, for example, a biaxially stretched polyamide resin film having a thickness of 15 μm and a low density polyethylene film having a thickness of 50 to 80 μm are used. Or three layers of a biaxially stretched polyester resin film having a thickness of 12 μm, a biaxially stretched polyamide resin film having a thickness of 15 μm, and a low density polyethylene film having a thickness of 50 to 80 μm, or a thickness of 15 μm There is known a laminated material including three layers of the biaxially stretched polyamide resin film, the biaxially stretched polyester resin film having a thickness of 12 μm, and the low density polyethylene film having a thickness of 50 to 80 μm. As a laminated material for manufacturing a pouch for a retort having a barrier property, for example, a biaxially stretched polyester resin film having a thickness of 12 μm, a biaxially stretched polyamide resin film having a thickness of 15 μm, and an aluminum film having a thickness of 7 to 9 μm are used. Laminated material consisting of four layers of foil and low-density polyethylene film having a thickness of 50 to 80 μm, or 2 having a thickness of 15 μm

However, in the transparent pouch for retort as described above, since it has transparency, for example, sunlight or fluorescence from the sun or a fluorescent lamp is transmitted, This is not preferable because there is a problem that the transmitted light affects the contents, for example, the contents are decomposed or altered, or photo-deterioration such as fading or the like is caused. Further, in the retort pouch made of the barrier material as described above, when a metal foil such as an aluminum foil or an aluminum vapor-deposited film is used as the barrier material, it has excellent barrier properties and light-shielding properties. It is extremely useful because it has a metal foil such as an aluminum foil or an aluminum vapor deposition film, but since it lacks in bending resistance and the like, pinholes are likely to occur, and there is a problem that its barrier property is significantly impaired. In addition, when used as a packaging container and then disposed of as waste, for example, when discarded by incineration or the like, metal such as aluminum remains, which may damage the incinerator, and its disposal suitability is lacking. At the same time, it causes problems such as environmental destruction and lacks environmental suitability.

There is a problem. On the other hand, by combining a colored layer with a barrier base material having a structure in which a vapor deposition film of an inorganic oxide such as aluminum oxide or silicon oxide is also provided on one surface of the base material film made of the above resin film or the like, However, in this case, the vapor-deposited film of an inorganic oxide such as aluminum oxide or silicon oxide, which constitutes the above-mentioned barrier base material, is an inorganic one. And, because it is made of glass and is extremely inert, therefore, even if a colored layer is provided simply on the surface of the vapor deposition film of an inorganic oxide such as aluminum oxide or silicon oxide, both of them are Laminates containing a barrier base material and a colored layer described above are no longer suitable for packaging containers because they lack affinity, etc., and are inferior in their dense adhesion properties, for example, phenomena such as delamination between layers occur. Materials for packaging etc. To work Eze, it is that no use things. Therefore, the present invention has strength,
Moreover, it has excellent physical properties such as weather resistance, heat resistance, pressure resistance, water resistance, heat seal, pinhole resistance, puncture resistance, and other properties, and especially prevents the permeation of oxygen gas, water vapor, etc. It has excellent barrier properties and light blocking properties, and withstands the heat and pressure treatment associated with the retort treatment process consisting of heat and pressure sterilization treatment, and has suitability for filling and packaging of contents, suitability for storage, etc.
