[Industrial Application Field] The present invention relates to a packaging bag for nutrient liquid that has excellent drop resistance and is capable of retort processing. [Prior Art] For example, packaging bags for nutrient solution containing nutrient solutions including infusions used in hospitals and other medical facilities are made from vinyl chloride film.
In this case, since the vinyl chloride film is sensitive to heat, the packaging bag containing the nutrient solution cannot be retorted, and the nutrient solution that can be stored is limited because it lacks oxygen barrier properties. In addition, the packaging bag for the nutrient solution has an inner bag made of vinyl chloride film, an inner bag made of a laminate film made of stretched polypropylene film and unstretched polypropylene film, and a laminate film made of polyester film coated with vinylidene chloride, stretched nylon film, and unstretched polypropylene film. It is also known that the outer bag is triple-layered, but in this case, the oxygen barrier property is improved, but it is still not sufficient, and there is a similar restriction on the nutrient solution that can be stored, and even in this case, Packaging bags containing nutrient solution cannot be retorted. Therefore, the packaging bag for the nutrient solution is constructed from a laminate film of polyester film, polyvinylidene chloride film, and unstretched polypropylene film.
A product was created that had good oxygen barrier properties and could be processed in a retort. In this case, the above-mentioned problems could be solved, but this packaging bag for nutrient solution lacks impact resistance, so if the packaging bag containing the nutrient solution was dropped, the bag would tear and the nutrient solution would scatter. A problem arose. [Problem to be solved by the invention] As mentioned above, the packaging bag for nutrient solution composed of a laminate film of polyester film, polyvinylidene chloride film, and unstretched polypropylene film has good oxygen barrier properties and is suitable for retort processing. However, on the other hand, it has the disadvantage that it lacks so-called drop resistance, which causes the bag to tear if it is dropped. This idea was made in view of the above points,
The purpose of the present invention is to provide a packaging bag for a nutrient solution that has excellent drop resistance and is capable of retort processing. [Means for Solving the Problems] The packaging bag for nutrient solution of the present invention has a composite film in which a stretched nylon film is provided between polyvinylidene chloride films, a stretched nylon film is bonded to one side of the composite film, and an unstretched polypropylene film is bonded to the other side. This laminated film and a laminated film in which aluminum foil is placed between a polyester film and an unstretched polypropylene film are stacked so that the unstretched polypropylene film is in contact with the film, and the peripheral portions are heat-sealed. [Function] The nutritional solution packaging bag of the present invention has a laminated film in which a stretched nylon film is bonded to a polyvinylidene chloride film on one side, and an aluminum foil is placed between a polyester film and an unstretched polypropylene film. is used on the other side, so the stretched nylon film compensates for the easily tearing property of polyvinylidene chloride film, which has good oxygen barrier properties, and has excellent drop resistance and can be retorted, while also being able to handle the nutrient solution contained in it. There are no restrictions and the scope of use is widened. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings. Figure 1 shows a packaging bag for nutrient solution according to the present invention.
This nutrient liquid packaging bag 1 is constructed by overlapping two laminated films 2 and 3 and heat-sealing the surrounding area 4 using a normal heat-sealing machine. The upper end opening 5 of this nutrient solution packaging bag 1 is sealed after being filled with the nutrient solution. Further, a nozzle (not shown) is attached to the spout 6 provided at the lower end of the nutrient solution packaging bag 1. As shown in FIG. 2, the laminated film 2 has the following features:
A composite film 10 with a thickness of 15 μm is provided on one side of a composite film 10 in which a stretched nylon film 9 with a thickness of 15 μm is provided between polyvinylidene chloride films 7 and 8 with a thickness of 15 μm.
A micron stretched nylon film 11 is bonded to the composite film 10, and an unstretched polypropylene film 12 having a thickness of 110 microns is bonded to the other surface of the composite film 10. As shown in FIG. 3, the laminated film 3 has the following features:
Stretched polyester film 13 with a thickness of 25 microns
and 20 micron thick aluminum foil 14 and thickness
110 micron unstretched polypropylene film 1
It is composed of three layers: 5. To make the nutrient solution packaging bag 1, the laminated films 2 and 3 are replaced with unstretched polypropylene films 12 and 1.
Laminated films 2 and 3 are stacked so that 5 are in contact with each other.
This is done by heat sealing the surrounding area. In the packaging bag for nutrient solution made in this way, the laminated film 2 is transparent, so the contained nutrient solution can be confirmed from the outside, and a stretched nylon film 9 is arranged between the polyvinylidene chloride films 7 and 8. This results in a structure that is strong against impacts and has excellent drop resistance. The drop resistance test results are shown in the table below. Condition 1 Sample: Bag 2 containing 1000 c.c. of water Dropping conditions: Naturally dropped onto a concrete floor from a height of 1.8 meters.
以上述べたように本考案によれば、酸素遮断性
にすぐれるので収容される栄養液に制限がなく利
用範囲が広くなり、また耐衝撃性にすぐれるので
不用意に落とした場合にも袋が破れて栄養液が飛
散ることがない。
As described above, the present invention has excellent oxygen barrier properties, so there are no restrictions on the nutrient solution that can be stored, allowing for a wide range of uses.Also, since it has excellent impact resistance, the bag can be used even if it is accidentally dropped. The nutrient solution will not scatter due to the rupture.
