DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail. A laminated film is used as the front and back synthetic resin films constituting the packaging bag of the present invention. Usually, the inner layer is a laminated film composed of a polyolefin-based resin layer having thermal adhesiveness, such as polyethylene or polypropylene (CPP), and is relatively mechanical such as biaxially oriented polyester, biaxially oriented polyamide, and biaxially oriented polypropylene. Using a film with strength as a base material, in order to further add necessary performance to these base materials, for example, aluminum foil, aluminum vapor-deposited film when light shielding is required, silica vapor deposition when air-proofing is required A packaging material in which a film and an ethylene-vinyl alcohol copolymer film are laminated is preferably used. Further, various selections are made depending on the type of the stored chemical solution. If the chemical solution requires retort treatment, it is necessary to select a material that can withstand the retort treatment.

[0006] The chemical liquid packaging bag of the present invention may be in any form such as a flat bag, a gusset bag or a self-standing bag, but from the viewpoint of resource saving, a gusset bag or a self-standing bag is preferable. In the case of a gusset-type chemical solution packaging bag, at least one synthetic resin film in the folded portion of the gusset uses a transparent film such as a silica-evaporated polyester film to reduce the contents such as the remaining amount of the chemical solution during administration. This is preferable because the state can be confirmed. In the case of a self-standing bag-type chemical liquid packaging bag composed of a light-shielding synthetic resin film, the contents can be confirmed while maintaining the light-shielding property by using a transparent film for the bottom gusset. The thickness of the packaging material used in the present invention is not particularly limited, but is generally 30 to

The hanging portion in the present invention is a portion for hanging the chemical solution packaging bag of the present invention. For example, when the hanging portion is hung on a hanging hook, the peripheral portion of the synthetic resin film is heat-welded to the packaging bag. At this time, one end is formed as a wide heat-welded portion, and a circular or elliptical through hole is formed at the center thereof to form a suspended portion. Further, the planned opening portion in the present invention may be any portion distant from the position where the spout of the packaging bag is provided, and a portion (projection) protruding from the packaging bag may be provided as the planned opening portion. It is preferable that these opening portions are provided with opening assisting means formed of a continuous or intermittent thin portion in the laminated film so that the opening can be easily opened by hand. As the opening assisting means, the continuous thin portion is preferably formed by a laser beam, and the intermittent thin portion is preferably formed by laminating another film on a perforated film. If a notch is provided in these opening portions as an opening start portion, the opening can be made easier by hand.

In manufacturing the chemical packaging bag of the present invention, the peripheral edge of the synthetic resin film is heat-welded. At this time, a circular or elliptical through-hole is formed in the heat-sealed portion at the end, and the synthetic resin film is suspended. Form a part. Further, when manufacturing the packaging bag by heat-welding the peripheral portion, a spout member is inserted between the front and back synthetic resin films, and heat-welded to form a spout. The spout member is made of a heat-adhesive resin such as polypropylene or polyethylene, and becomes thinner as the heat-adhered portions are located on the left and right ends so that it can be completely heat-adhered when installed in a packaging bag. Molded ones are preferred.

The present invention will be described more specifically with reference to the drawings. FIG. 1 is a plan view of a gusset-type chemical solution packaging bag of the present invention, and FIG. 2 is a perspective view of the packaging bag filled with a chemical solution and suspended.
