Description of the Related Art Conventionally, various liquid packaging containers for storing various products such as foods and drinks, liquid detergents, etc. have been proposed, and as the liquid packaging container, a paper pack, a standing pouch, etc. are available. Are known. However, in the above liquid packaging container, there is a problem that the inclusions undergo photodegradation such as fading during long-term storage. Therefore, as a liquid packaging container for preventing the optical deterioration of the inclusions, there has been proposed a container in which the inner surface of the container is formed of a metal layer such as an aluminum foil. The container using this metal foil has the effect of completely blocking the permeation of oxygen, but it is difficult to separate the metal layer from the other layers, and it is difficult to incinerate, which is not preferable in terms of environmental problems, etc. . Therefore, it has been proposed to use a plastic film having a metal oxide vapor deposition layer such as an aluminum oxide vapor deposition layer. The aluminum oxide vapor deposition layer is a thin film with a maximum thickness of 800 Å or less and is also transparent, so it is handled like printing ink and does not require separate incineration, so environmental problems do not occur. However, oxygen transmission cannot be completely prevented, and a small amount of oxygen invades. In addition, as a liquid packaging container having a light-shielding property without having a metal foil layer such as an aluminum foil, an actual container is used.
Japanese Patent No. 5445 proposes a liquid paper container having a light-shielding laminated structure of paper / direct color layer / paper. However, in the liquid paper container, it is particularly necessary to provide a light-shielding layer made of a synthetic resin. However, since it is difficult to separate the light blocking layer from the paper, recycling is difficult and there is an environmental problem. Further, Japanese Patent No. 3017399 discloses a container formed of a sheet in which a gray ink layer having a hue of 5B to 5P, a saturation of 0, and a brightness of 6 to 7 is provided on the outer surface of a resin sheet. However, in such a container provided with a gray ink layer, the content of the contents looks like a black and dirty color, which gives an unpleasant sensation and thus has a problem of deteriorating the commercial value.

A pouch made of a plastic film having a light-shielding layer of 5 to 6.0% and the remaining white color formed by a printing ink. Pouches made of plastic film have been widely used because they can easily see the contents inside when food is included, which attracts consumers' attention and increases the commercial value, but when oxygen permeates the film. Since the contents of the inclusions are altered, the oxygen barrier film is used to suppress the passage of oxygen as little as possible. As the oxygen barrier plastic film, a film provided with a metal oxide vapor deposition layer such as an aluminum oxide vapor deposition film is preferable. Ethylene-vinyl alcohol copolymer is widely used for oxygen barrier layer, but since water resistance is poor during retort and deteriorates, the oxygen barrier layer is not preferable for pouches used for retort and aluminum oxide vapor-deposited layer, etc. The metal oxide vapor-deposited layer is also preferable in terms of environmental resistance.

価値が著しく損なわれる。As the metal oxide deposited layer, a silicon oxide deposited layer other than an aluminum oxide deposited layer may be used. However, the SiO 2 vapor deposition film does not have an oxygen barrier property, and the SiO vapor deposition film has an excellent oxygen barrier property, but is unstable.
Moreover, since it becomes yellowish brown and the appearance deteriorates, SiO and Si
A preferable effect is obtained by using SiO x blended with O 2 and x = 1.7 to 1.8. Further, a good effect can be obtained by forming a silicon oxide layer on the aluminum oxide vapor deposition film to protect the aluminum oxide vapor deposition film. However, if a metal oxide vapor deposition layer is used, even if the amount of oxygen permeation can be reduced, some oxygen intrusion occurs. Further, the inclusions are deteriorated by the light passing through the film, but according to the research by the present inventor, the deterioration due to light and the deterioration due to oxygen have a synergistic effect, and therefore the deterioration cannot be prevented unless the passage of light is prevented. Moreover, the photodegradation occurs not only in the ultraviolet region but also in the visible wavelength region. In order to prevent the transmission of ultraviolet light, the plastic film forming the pouch can be cut almost completely by coloring it in white, but the visible light cannot be cut completely. On the other hand, if a black or gray colored layer is arranged, it is possible to prevent the transmission of visible light, but if such a color is added, the food and drink contained in the pouch will look dark and dirty, and it will be unpleasant. Because it gives an impression, the product value is significantly impaired.

ない。The present invention prevents the color of the inclusions from appearing black by providing the laminate film forming the pouch with an ink containing a white color. As described above, in the present invention, it is important that no black color is arranged on the outer surface side of the laminate film forming the pouch. A light-shielding layer made of an ink containing white, black, red and / or yellow is formed on the inner surface side of the white ink layer. The ink layer arranged on the inner surface side of the white ink layer contains 0.5 to 6.0% of black, 0.5 to 6.0% of crimson and / or yellow, and the remaining white color, and optionally other colors. Must be a layer of printing ink. Outside this range, transmission of light cannot be prevented and light deterioration occurs. The ratio of the colors of white, black, red and / or yellow contained in the light-shielding layer disposed on the inner surface side of the white ink layer may be a layer formed of one kind of mixed ink or one kind or two.
A layered layer containing a mixture of two or more species may be in this range in total. This is because light is blocked by the layer containing this proportion of color. The light-shielding layer made of an ink containing 3 to 4 kinds of colors on the inner surface side in a specific ratio can block light in the visible region from the ultraviolet.

れる。That is, the barrier pouch of the present invention is provided with at least one white ink layer, and on the inner surface side thereof a light-shielding layer of an ink containing white, black, crimson and / or yellow colors and the pouch. The hue according to the Munsell system must be 5.5 P to 5.0 GY and the saturation must be 0.2 to 5.0. If the hue and saturation are out of the range, even if the colors of white, black, crimson and / or yellow are used, it is not possible to prevent the color of the inclusions from appearing black and dirty. Hue by Munsell system is 5.
From 5P to PB side, the visible light is transmitted,
There is also a problem that the tendency to transmit ultraviolet light increases from GY to BG. To explain in more detail the layer containing the color of black, white, crimson and / or yellow on the inner surface side of the laminated film constituting the pouch in a specific ratio, it may be a layer in which these colors are mixed, or a layer containing one color each. At least three layers may be stacked, or a layer containing two colors and a layer containing the remaining one kind may be stacked. Also, colors other than black, white, and crimson may be added, but the hue is 5.5P or more depending on the Munsell system.
Do not add an amount such that 5.0 GY has a saturation outside the range of 0.2 to 5.0. The pouch of the present invention has a light transmittance of 15% or less in the ultraviolet region of 390 nm or less and 450 n in the visible region.
When m is 27% or less, 600 nm is 35 or less, 700 nm is 38% or less, and the oxygen permeability is 40 cc / m 2 day or less, a very excellent deterioration preventing effect is exhibited. As the plastic film, PET film is preferably used on the outer surface side because it has good bag-making properties, printability, and gloss. Impact resistance is improved by using nylon film as the intermediate layer. The inner surface is preferably an olefin film such as polyethylene or polypropylene because of its heat sealing property. As a particularly preferable constitution of the laminated film, from the outer surface, aluminum oxide vapor-deposited PET / white ink layer / white ink layer / light-shielding layer / nylon / polypropylene can be mentioned.

が存在しないことがわかる。Examples of the form of the barrier pouch of the present invention include a self-supporting pouch called a standing pouch, a three-way seal bag, a four-way seal bag, and a pillow type bag. In particular, in the case of a self-supporting pouch, two body members and a bottom member are composed of the laminated film having the above layer structure,
Replace only the bottom material with the laminated film with the above layer structure,
It is possible to use a laminated film of aluminum oxide vapor-deposited PET film / white ink / white ink / nylon / polypropylene from the outside, or a laminated film of PET film / aluminum foil / nylon / polypropylene from the outside. . Next, Table 1 shows the constitution of a typical laminate film used in the present invention, the composition of a typical light-shielding layer formed by a printing ink, and the composition of the ink. It can be seen that the left side of Table 1 is the outer surface side of the film, the layer containing the white color is arranged, and there is no black on the outer surface side.
