Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patch bag for patches, and more particularly, a patch bag for patches suitable for filling and packing patches such as poultices containing medicinal components, such as analgesic and anti-inflammatory agents. It is about.

[0002]

2. Description of the Related Art Conventionally, various types of patch bags for patches have been developed and proposed. Generally, at least the heat seal property is improved from the inner surface contacting the contents to the outer surface. A packaging material composed of a resin film layer, a metal foil layer, and a paper material layer, which are laminated in this order, is laminated with the film layer surfaces of the resin having the heat-sealing properties facing each other, and the polymerized end of the outer periphery thereof is superposed. A bag body in which a part is heat-sealed is used. By the way, in the above bag body, a metal foil layer rich in gas and water vapor barrier properties is usually used in order to prevent entry of oxygen, water vapor, light rays and the like from the outside air. As a typical metal foil layer having excellent gas and water vapor barrier properties as described above, an aluminum foil or a vapor deposition film thereof is usually used.

[0003]

However, it is difficult to separate the aluminum foil or the like from the packaging material having the aluminum foil or the vapor deposition film thereof as described above, and it is often combustible. It is incinerated in the same way as. When incinerated while containing the aluminum foil or its vapor-deposited film, the burning calorie at the time of incineration becomes high, which may damage the incinerator and the like. However, there is a problem in that the residual remains and causes environmental damage. Further, as described above, it is difficult to separate and remove the aluminum foil and the like from other materials, and therefore it is not suitable for recycling. Therefore, the use of the aluminum foil and the like is from the viewpoint of resource protection. Is also unfavorable. It is conceivable to use a film of a resin having a gas barrier property, such as a film of polyvinylidene chloride resin, a film of a saponified product of ethylene-vinyl acetate copolymer, instead of the aluminum foil or the vapor deposition film thereof. However, these films are inferior in function to metal foils and the like, and are not yet sufficiently satisfactory. Therefore, the present invention is easy to incinerate waste,
Another object of the present invention is to provide a packaging bag for medicated patches which is excellent in protection of the contents.

When a patch such as a poultice was filled and packaged in the patch bag, the content of the patch was sufficiently protected and the bag could be sufficiently used as a patch bag for the patch, and after use. The present invention has been completed by finding that the waste can be incinerated in the same manner as ordinary flammable substances.

That is, the present invention has a constitution in which a film layer of a resin having at least a heat seal property, a metal foil layer, and a base material layer are laminated in this order from the inner surface side in contact with the contents to the outer surface side.
